Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a supervisory control system for supervising and controlling the operation state of a complicated and large-scale industrial system such as an electric power system and water supply and sewerage using a computer.

[0002]

2. Description of the Related Art In recent years, a monitoring and control system for monitoring and controlling the operation status of an industrial system such as an electric power system and water supply and sewage has recently been developed.
The area of monitoring and control has been widened and scaled up, and the monitoring control function has been advanced, and there has been a demand for the construction of a system that can cope with such widening, large scale and advanced functions.

[0003] In addition, due to the progress of the advanced information society, it is no longer necessary to supply power stably in daily life. It is also important to continuously operate the monitoring and control system to ensure high reliability.

[0004] In this regard, the conventional monitoring and control system controls a huge number of control target facilities distributed over a wide area, so that a part controlling these facilities (hereinafter referred to as a business office) has a role and a workload. In such a manner as to be hierarchically divided and arranged according to.

[0005] For example, in a power system monitoring and control system for monitoring and controlling a power system, a central power supply command center is set as a business of a highest control hierarchy, and a plurality of main power supply control stations are hereinafter set as a next control hierarchy. The supervisory control system is configured as a business establishment located, and a plurality of power plants and a plurality of substations as business establishments located in the next control hierarchy.

[0006] Each business establishment in the monitoring and control system stores information (system information) relating to system equipment such as the status and operation of the equipment and equipment handled by the business establishment as an equipment database, and the system information and the configuration of the business establishment itself. A business application program unique to a business site designed based on information (operational information) related to an operation system for operating the business facilities, such as its scope and its jurisdiction; objects such as state change data (SV) of equipment and telemeters It refers to a monitoring business object for monitoring a value (TM), an operation business object for performing a start / stop operation, an opening / closing operation, and the like of a facility device. Note that an application program is simply referred to as an application.
To be executed.

Further, in order to realize high reliability against the above-mentioned failure, computer systems in each business office are multiplexed (usually duplicated). That is, each business office has a regular (active) computer system having a business application and a standby computer system having the same business application, and the regular computer system and the standby computer system store an equipment database. The shared disk and the shared memory that are held can be accessed. Therefore, when a failure occurs in the regular computer, it is possible to switch from the active computer to the standby computer and continue the business.

[0008]

Since the above-mentioned wide-area and large-scale monitoring and control functions and the sophistication of the monitoring and control functions are continuously progressing, new introduction / extension of the system equipment and change of the operation method of the system equipment are required. There is a demand for a highly scalable monitoring and control system that can flexibly cope with such situations.

[0009] However, in the conventional monitoring and control system, information is shared between offices and information is transmitted in cooperation with each other even though the offices distributed are arranged hierarchically in a network. Due to the fact that little is done and that business applications rely on system information and operation information, new installation and expansion of system equipment and changes in the operation method of the system equipment, etc.
It was not possible to flexibly respond to expansion and modification of the entire system.

For example, in a conventional power system monitoring and control system, when newly introducing or expanding a system facility, the facility database of a plurality of establishments related to the extension facility is changed while maintaining consistency, and each of the plurality of establishments is changed. Since it is necessary to modify business applications related to input / output processing of signals (SV data) representing the state of equipment and equipment and operation signals while maintaining consistency with each other, a great deal of human labor is required for the modification and modification work. The result was spending.

In a conventional monitoring and control system, operation information such as the configuration of a business establishment itself and its jurisdiction is
It was not physically stored as a component within a business establishment, but was fixedly treated as additional information at each business establishment. In other words, the business application designer uses the business-specific operation information stored by himself / herself, for example, based on the name of the business office and its jurisdiction (such as a group of subordinate business offices or a superordinate business office under control). A business application corresponding to the operation information is created, and the operator (operator) performs an operation related to the business application while empirically using the stored operation information.

Therefore, for example, when the operation system such as the jurisdiction of a certain business establishment is changed in accordance with the expansion of the business establishment, all the business applications and design in the business establishment are changed according to the operation information based on the changed operation system. Since it is necessary to make a large-scale change in the entire system such as a database in the office, even when a small-scale operation system change is made, the cost and human burden associated with the change work have increased.

Furthermore, in the conventional monitoring and control system, the configuration of the computer system at each business office, the connection form (network) between the business offices (computer systems) distributed and arranged in a wide area, and the computer system at each business office Are fixedly set, and the business application of each office is designed according to the set contents. This means that in the conventional monitoring and control system, it is possible to cope with a change in the system configuration and business expansion only within a certain limited range (for example, on a business unit basis).

Therefore, the system configuration is changed (for example, the execution position of the business application is moved to another business office, etc.) and the business is expanded (for example, the jurisdiction range) beyond the restriction range. It is very difficult to monitor and control offices that exceed the limit, or perform system simulation in cooperation with multiple offices, etc.), and temporarily change or expand the system configuration beyond such a limited range. In order to do so, it is necessary to review the system configuration over the entire monitoring and control system and make design changes for a large number of existing business applications, resulting in enormous changes and expansion costs, and significant human labor. Needed.

According to the conventional monitoring and control system, the computer systems in the office are multiplexed in order to realize high reliability. However, in all offices, the same standby computer system as the active computer system is used. A computer system had to always be prepared, and it could not be said that computer resources were used efficiently. In addition, since all the multiplexed computer systems have offices, the system becomes very expensive.

[0016] Further, the conventional high reliability measures in the monitoring and control system are limited to high reliability within the business establishment, and all the multiplexed computer systems in the business establishment are stopped due to a wide area disaster or multiple failures. If it did, the business would have to stop working, which was not a radical measure of high reliability.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and its overall purpose is to separate and independence of business applications from system information and operation information, thereby newly introducing and expanding system equipment and installing the system equipment. An object of the present invention is to provide a monitoring and control system that can flexibly cope with expansion and modification of the entire system such as a change in an operation method.

Next, a description will be given of the overall operation when the main power supply dispatching station 4a performs the monitoring work of the system equipment of the other establishments (the power plant 5, the substation 6a).

The substation monitoring service execution unit 52a of the substation monitoring service execution unit 52 uses the substation data transmitting / receiving
A command is sent to the substation d for requesting substation data including the operating state and the TM value of the predetermined substation equipment 2d in order to execute a monitoring control task with the target of monitoring and control. The substation data transmission / reception unit 50d responds to the transmitted substation data request command by the substation data storage unit 50d.
The substation data of the equipment 2d to be monitored and controlled is read from b and sent to the substation monitoring task execution means 52a.

The substation data sent from the substation data transmission / reception unit 50d by the processing of the substation monitoring service execution unit 52a is sent to the display data creation unit 52c. On the other hand, display regulation data is sent from the data file unit 52b to the display data creation unit 52c.

The substation data is stored in the display data creating means 52c.
Is read through the data reading means 60 and sent to the preprocessing means 61 for preprocessing. The preprocessed substation data is sent to the display data composing unit 65 together with the display prescription data. Based on the substation data and the display prescription data, the data associating unit 64 performs processing, for example, on the monitored equipment 2d itself and its status. System monitoring screen data in which the abnormal state, the TM value, and the like are represented by graphic symbols, display colors, character data, and the like are created as display data. This display data is sent to the display unit 6d3 via the display data external I / F 66. As a result, a system monitoring image including the substation equipment 2c to be monitored and controlled is displayed on the display screen of the display unit 6d3. As a result, the operator of the computer system 6A3 monitors the system monitoring image on the display unit 6d3, and thereby the substation equipment 2 of the substation 6a.
The state of d, the TM value, and the like can be recognized.

Similarly, the power generation monitoring service execution unit 55a of the power generation monitoring service execution unit 55 sends a command to the power generation data transmission / reception unit 53d requesting the power generation data for the predetermined power generation equipment 2c to be monitored and controlled. Power generation data transmission / reception means 53d, power generation monitoring task execution means 55
a, display unit 5d by processing of display data creation unit 55c
The display screen 3 shows the power generation equipment 2
c is displayed, and the computer system 5A is displayed.
The status of the power generation equipment 2c of the power plant 5, the TM value, and the like can be monitored via the third operator.

Similarly, the system monitoring service execution unit 5
7 by the system monitoring task execution means 57a to the system data transmitting / receiving means 56c.
When a command for requesting the system data for which d is to be monitored and controlled is sent, the display screen of the display unit 4d2 is displayed on the display screen of the display unit 4d2 by the processing of the system data transmitting / receiving means 56c, the system monitoring service execution means 57a, and the display data creating means 57c. A system monitoring image including the target substation equipment 2c, 2d is displayed, and the status, TM value, and the like of the power generation equipment 2c, 2d of the substation 5, 6a can be monitored via the operator of the computer system 4A3.

As described above, in the state where the system monitoring screen is displayed at each of the business sites (the substation 6a, the power plant 5, and the main power supply command center 4), the substation data conversion means 50a of the substation information control unit 50 uses the substation equipment. , The equipment data based on the SV information or TM information of the predetermined equipment 2d is periodically acquired, converted into substation data based on the SV data or TM data, and
c (FIG. 7; step S1).

At this time, the substation data receiving means 50c
The transmitted substation data of the specified equipment 2d is received, and it is determined whether the substation data is SV data or TM data (step S2). If the substation data is determined to be SV data, it is obtained last time. Equipment 2d
Is read out from the substation data storage means 50b (step S3), and it is determined whether the operation state of the previously obtained substation data matches the operation state of the currently received substation data. (Step S
4). As a result of this comparison, when it is determined that the state of the equipment 2d has changed (step S4; NO), the status is transmitted to the substation monitoring service execution unit 52a of the substation monitoring control unit 52 via the substation data transmission / reception unit 50d. To send a notification signal indicating the state change of the equipment 2d (step S5),
The current state of the equipment 2d is stored as substation data in the substation data storage unit 50b (step S6). On the other hand, when the state of the equipment 2d does not change as a result of the comparison determination in step S4 (step S4; YES),
The process ends.

For example, when the predetermined equipment 2d is a circuit breaker, the state of the circuit breaker is "closed" according to the previous transformation data and the state of the circuit breaker is "open" according to the currently received transformation data. When a change occurs, a notification signal indicating a state change of the equipment 2d is transmitted to the substation data transmitting / receiving means 50d.

On the other hand, if the substation data is determined to be TM data, the substation data receiving means 50c reads the rated value information and the permissible range information relating to the equipment 2d from the substation data storage means 50b (step S7).
It is determined whether the substation data corresponding to the rated value information is within the allowable range (step S8). As a result of the comparison, if the equipment 2d indicates a normal value and the TM value of the currently acquired substation data is out of the allowable range (step S8; NO), the TM value of the equipment 2d is abnormal. Is transmitted to the substation monitoring service execution unit 52a of the substation monitoring control unit 52 via the substation data transmission / reception unit 50d (Step S).
9). On the other hand, the equipment 2
If the TM value of d does not deviate from the allowable range (step S8; YES), the process ends.

When an abnormality occurs in the TM value (step S8; NO), the equipment 2d indicates an abnormal value by the above-described comparison processing based on the acquired substation data (TM data), and acquires the abnormal value. If the TM value of the obtained transformation data is within the allowable range (step S10), a notification signal indicating that the TM value of the equipment 2d has returned to the normal value is transmitted through the transformation data transmission / reception means 50d. Substation monitoring service execution means 5 of monitoring control unit 52
2b (step S11), and the current TM value of the equipment 2d is stored in the substation data storage unit 50b (step S12).

Thus, the substation monitoring service execution means 5
When the notification signal is transmitted to the second, the display request data based on the notification signal is sent to the display data creation unit 52c by the processing of the substation monitoring work execution unit 52. On the other hand, display regulation data is sent from the data file unit 52b to the display data creation unit 52c.

The display request data sent from the substation monitoring service execution means 52a is read via the data reading means 60 of the display data creation means 52c and is displayed.
Is analyzed.

That is, for example, when the notification signal indicates a state change of the equipment 2d, the display request processing means 62 creates processing data for changing the color of the graphic symbol of the equipment 2d, and generates the notification signal. Indicates an abnormality in the TM value of the equipment 2d, the abnormality of the TM value is displayed on the screen of the equipment 2d.
Process data for representing the graphic symbol d by flicker display is created (FIG. 8, step S20).

The processing data created by the display request processing means 62 is sent to the display data forming means 65 together with the display regulation data (step S21). The display data composing means 65 changes the display color of the corresponding graphic symbol of the equipment 2d by the processing of the data associating means 64 (in the case of a state change) based on the transmitted processing data and the display regulation data, or the same. Display data for flickering the display color (in the case of an abnormal TM value) is created (step S2).
2), the created display data is transferred to the display data external I / F 6
It is sent to the display unit 6d3 via the terminal 6 (step S23). As a result, on the display unit 6d3, a system monitoring screen is displayed in which the state change of the substation equipment 2d to be monitored and controlled and the abnormality of the TM value can be recognized very easily by the display color change or flicker of the graphic symbol. be able to.

On the other hand, when a notification signal indicating the return of the TM value is transmitted to the substation monitoring service execution means 52, the above-described substation monitoring service execution means 52a and display data creation means 52
By the processing centering on the display request processing means 62c, display data in which the flicker of the display color of the graphic symbol is stopped is created and displayed on the display unit 6d3. As a result,
The return of the TM value of the substation equipment to be monitored and controlled to the display unit 6d1 can be recognized very easily by stopping the flicker of the graphic symbol.

Similarly, the equipment data based on the SV information or TM information of the predetermined equipment 2c in the power generation equipment is transmitted to the power generation data conversion means 5 of the power generation information control unit 53.
SV data or TM acquired periodically by 3a
After being converted into power generation data based on the data, the power generation data is received by the power generation data receiving means 53c.
When the state of the equipment 2c or the abnormality of the TM value occurs in the equipment 2c by the comparison processing of 3c, the power generation monitoring business execution means 5
A notification signal is transmitted to 5a. Then, the display request data based on the notification signal is sent to the display data creating means 55c by the processing of the power generation monitoring task executing means 55a, and the facility equipment is generated based on the processing data and the display regulation data created by the processing of the display request processing means 62. The display data for changing the display color of the graphic symbol 2c (in the case of a state change), flickering the display color (in the case of an abnormal TM value), and stopping the flicker (in the case of returning the TM value) is a display data configuration. It is created by means 65. The created display data is displayed via the display unit 5d3. As a result, through the display screen of the display unit 5d3, the state change of the power generation equipment 2c to be monitored and controlled, the abnormality of the TM value, and its return can be very easily recognized by the display color change and flicker of the graphic symbol. .

On the other hand, the substation data transmission means 50e reads out the substation data based on the current operation state or the TM value stored in the substation data storage means 50b (FIG. 9, step S30), and reduces this substation data. (Step S31).

For example, if the substation data read from the substation data storage means 50b is data (state change data) representing the operating state of the plurality of equipment 2d1 to 2dn (YES in step S31a), the substation The data transmission means 50e is provided with the plurality of equipment 2d1 to 2d.
The state change data of n is logically reduced to the change data of one piece of equipment 2d1 having the logical operation value of the operation state value (open: 0 or closed: 1) (step S31b).

Further, the substation data stored in the substation data storage means 50b stores the TM of the plurality of equipments 2d1 to 2dn.
If the data is the data (TM data) representing the value (NO in step S31a), the substation data transmitting unit 5
0e numerically reduces the TM data of the plurality of equipments 2d1 to 2dn into substation data of one equipment 2d1 having, for example, an average of the respective TM values (step S).
31c).

The power generation data transmitting means 53e also performs steps S30 to S30 on the current operation state or power generation data based on the TM value stored in the power generation data storage means 53b.
By executing the same processing as in step S34, the reduced power generation data is generated.

The substation data and power generation data thus reduced are converted into first system data and second system data having a transfer address corresponding to the main power supply command center 4a, respectively, in the substation operation information management unit 51. And the power generation operation information management unit 54.

The first system data sent to the substation operation information management unit 51 is received by the data receiving means 51b and sent to the judging means 51c. The judging means 51c
Referring to the jurisdiction range data and the command authority data including the higher-level office data stored in the storage unit 51a (see FIG. 1).
0, step S40), whether or not the transfer destination at the transfer address of the transmitted first system data is included in the higher-level business establishment data, that is, the jurisdiction range of the business establishment of the transfer destination (basic power supply command office 4a) The transfer source office (substation 6a)
Is determined (step S41), and if the result of the determination is YES, it is determined whether or not the higher-level office has command authority (step S4).
2). Now, according to the upper-level office data and the command authority data stored in the storage unit 51a, the upper-level office of the substation 6a is the main power supply command station 4a, and the main power supply command station 4a has the command authority. Step S4
1 and the result of determination in step S42 is YES
Then, the data transfer unit 51d transfers the first system data to the system information control unit 56 of the main power supply command center 4a, and ends the process (step S43). If the determination in step S41 or S42 is NO, the process ends.

Each unit of the power generation operation information management unit 54 also executes the same processing as in steps S40 to S42 described above, and transmits the second system data to the main power supply command center 4
A is transferred to the system information control unit 56 of FIG.

The first system data and the second system data transferred to the system information control unit 56 are received by the system data receiving means 56a. At this time, the system data receiving means 56a detects a system change such as a state change of the substation equipment 2d and the power generation equipment 2c or an abnormality in the TM value based on the first system data and the second system data (FIG. 11, step S50), and a notification signal indicating the system change is transmitted to the system monitoring control unit 57 (step S51). In addition, when at least one of the first and second system data is state change data, the system data receiving unit 56a determines at least one of the corresponding substation equipment 2d and the power generation equipment 2c. The current state is stored in the system data storage unit 56b as system data.

When an accident occurs in the substation equipment, for example, the system data receiving means 56a executes step S
In the process of 51, the first system data detects that a plurality of substation equipments (for example, disconnectors and circuit breakers) related to the failed part change from closed to open at the same time, and is separated by the change. Circuit information is also detected. At this time, the system data receiving means 56a transmits a notification signal indicating a circuit (a bus or the like) disconnected due to the state change of the plurality of equipment to the system monitoring control unit 57 in addition to the state change, and transmits Is stored in the system data storage means 56b.

On the other hand, if at least one of the first and second system data is data indicating an abnormality in the TM value, the system data receiving means 56a outputs the first and second system data.
If the data indicating the return of the TM value is transmitted as at least one of the system data (YES in step S52), a notification signal indicating the return of the TM value is transmitted to the system monitoring control unit 57 ( Step S53).

Thus, the system monitoring control unit 5
7, the display request data based on the notification signal is sent to the display data creation unit 57c by the processing of the system monitoring work execution unit 57a, and the processing created by the processing of the display request processing unit 62. The display colors of the graphic symbols of the substation equipment 2d and the power generation equipment 2c are changed based on the data and the display regulation data (in case of state change), the display color is flickered (in case of abnormal TM value), and the flicker is stopped (TM) The display data is generated and displayed through the display unit 4d2.

As a result, the status of the equipment 2d of the substation equipment, which is the business of the substation 6a, and the monitoring of the abnormal value and return of the TM value, etc., and the status of the equipment 2c of the power generation equipment, which is the business of the power plant 5, are performed. Computer system 4A2 of the main power supply command center 4a, which is another business site, for monitoring abnormalities and return of the TM value, etc.
This can be done very easily by changing the display color of the graphic symbol on the display screen of FIG.

In other words, according to this configuration, the monitoring of the equipment 2d and 2c of another business (the substation 6a and the power plant 5) from one business (the main power supply commanding station 4a) is performed by the substation monitoring business application. , Power generation monitoring application and power system monitoring application, etc., can be realized without changing the objects and system configuration (change of communication configuration, change of database, etc.) unique to each business establishment. A high-priced power system monitoring and control system can be provided.

Further, since the display model 32 is realized as a display unit separately from the business application,

Further, by the processing of the consistency assurance means 95, the jurisdiction range data [subordinate office: substation 6a, power station 5) of the data storage unit 82a is changed to [subordinate office: substation 6a]. (See FIG. 19).

On the other hand, the operation information management unit 9 of the power plant 5
At 3, the transmitted jurisdiction range change command is received via the data receiving means 54b and the data consistency assurance means 9 is received.
8 and the content of the jurisdiction range data stored in the data storage unit 54a [upstream office: basic power supply command office 4a] is changed to [upstream office: basic power supply command office 4c] ] (See FIG. 19).

In the above-described example, the change of the jurisdiction range in the expansion of the main power supply dispatching station has been described. However, the jurisdiction based on the expansion of the lower-level offices (substations and power plants) and the expansion of the main power transmission dispatching station is described. A change in the range can be dealt with by changing only the operation information management unit of each office by the same processing.

Further, in the above-described configuration, as an example of the change of the operation system data, the change of the jurisdiction based on the establishment of a new office has been described. Only the operation information management unit of the establishment needs to be changed.

As described above, according to this configuration, each business establishment (basic power supply dispatching station, substation, and power plant) uses the operation information management unit, which models information related to the operation system, as a business application. Because we have it independently,
Data related to the operation system can be changed (for example, change of the jurisdiction of the business establishment) regardless of the business application or the like. That is, the change of the operation system can be realized with low cost and low labor without making a large-scale change over the entire system, and the flexibility of the power system monitoring and control system can be further improved.

Subsequently, in the power system monitoring and control system, a process of detecting that a failure has occurred in at least one of a plurality of computer systems constituting a certain business office, and processing of an object mounted in the computer system. Means for specifically realizing processing for detecting the occurrence of a failure in a subsystem (such as a business application or a system information model) and processing for managing (copying, moving, deleting, etc.) objects in the computer system in object units. Will be described.

In FIG. 20, an office (for example, substation 6)
A plurality of computer systems (two in the figure) constituting a) 6
A1 and 6A2 have configuration management units 100A and 100B as function realizing means of the configuration management subsystem 36 embodied by processing of the CPUs 6a1 and 6a2, respectively.

Further, the two computer systems 6A1, 6A
2 is stored in the memory 6c1 and stored in the CPU 6a.
A plurality of business applications (business objects, shown as objects A, B, and C in the figure) such as a substation monitoring business application 52a and an operation business application 75a, which are embodied by processes such as 1 are mounted. Descriptions and illustrations of other business applications, subsystems, and platforms in the substation 6a are omitted.

The configuration management unit 100A of the computer system 6A1 periodically starts up, checks the execution state of each object (object A, object B, object C) existing in the computer system 6A1, and checks the execution state of the objects A, B. , Object C) to determine the status (for example, normal or abnormal) of the object, and the status of each of the objects A, B, and C obtained by the determination process of the object status determination unit 101 to an object status file. And an object management means 102 for storing the information as an object. The state of the object is, for example, UNI
It can be obtained by using the system function of X.

The configuration management unit 100A is connected to another computer system 6A2 or its own computer system 6A1.
Various kinds of requests and information such as an object state inquiry request transmitted through an input unit of the above are received, and the processing means (for example, the object management means 102) according to the destination information added in the request and information is received. The message receiving means 103 to be transferred, and the object status file stored in the object management means 102 are taken out in response to the object status inquiry command transferred from the message receiving means 103, and the request source (the other computer system 6
A2, or a message transmitting means 104 for returning to the display unit (not shown) of the computer system 6A1.

Further, the configuration management unit 100A performs object operation / management via the object management means 102 based on other requests (for example, a new object registration request, an object deletion request, etc.) sent from the message receiving means 103. It has an object operation mechanism 105 for performing.

As shown in FIG. 21, the object status file stored by the object management means 102 has a structure in which an object name (object A, object B, object C) and its status (normal or abnormal) are paired. ing. Note that the object state determination means 10
1, the object management means 102 and the object operation mechanism 105 are collectively
Call.

The configuration management unit 100A periodically detects that the computer system 6A1 is operating normally, and outputs a message (Alive) indicating the normal operation.
Message) to the configuration management unit 100B of the other computer system 6A2 via the message transmitting means 103, and from the other computer system 6A2, received via the message receiving means 104 and transferred. A computer status storage means 111 for storing the status of another computer system 6A2 as a computer status file based on the received Alive message.

The computer failure detection means 110 is started periodically or each time the above-mentioned Alive message is transmitted and received, and refers to the computer status file stored in the computer status storage means 111 for a predetermined time or more.
If there is a computer system that has not received the ve message, it is determined that a failure has occurred in the computer system, and a failure occurrence command (failure occurrence message) is transmitted to another computer system via the message transmission unit 104. It is supposed to.

As shown in FIG. 22, the computer status file stored by the computer status storage unit 111 includes at least the computer system name (in FIG. 22, the computer system 6A2,
(Computer system 6A3 and computer system 6A4), the computer status, and the last Alive message reception time.

Since the Alive message is always sent when the computer system is normal, the computer system status in the computer status file is all normal at normal times. In this configuration, the Alive message reception time is used. Detects computer system failures.

That is, the computer fault detecting means 110
The Alive message reception time is referred to and compared with the current time. If there is a computer system that has passed a predetermined time from the reception time to the current time, it is determined that a failure has occurred in the computer system and the The computer status is rewritten abnormally, the computer system name is read from the file, and a failure occurrence command is transmitted. Similarly to the computer system 6A1, the computer system 6A2 also has a message receiving unit 103B, a message transmitting unit 104B, a computer failure detecting unit 110B, a computer state saving unit 111B, and an object management operation unit 10.
6B.

For example, the object state determination means 101
When it is determined that the object B in the computer system 6A1 is abnormal, the determination result is stored in the object state management means 102 as an object state file.

At this time, for example, another computer system 6A
2 sends an object state inquiry request via the message receiving means 104, the object state file is extracted from the object file means 102 by the processing of the message transmitting means 104 in response to the object state inquiry request, and the other computer system 6A2 Will be replied to.

The other computer systems 6A2 to 6A4
Failure detecting means 1 started every time an Alive message is received from the server via the message receiving means 103
10 refers to the computer status file stored in the computer status storage unit 111.

At this time, if there is a computer system 6A4 in which the Alive message reception time has passed a predetermined time or more from the current time, the computer failure detection means 11
0, it is determined that a failure has occurred, and a failure generation command of the computer system 6A4 is sent to the computer systems other than the computer system 6A4 by the message transmitting means 1.
04 automatically.

That is, according to this configuration, the failure detection of the object and the computer system can be performed without changing the business object (business application program) or the other object (subsystem) itself, that is, independently of the content of the object. Fault detection can be performed, and the flexibility related to fault detection of the power system monitoring and control system can be improved.

On the other hand, the object operating mechanism 105 of the computer system 6A1 includes an object registration unit 120, an object deletion unit 121, and an object transmission unit 12.
2 and an object receiving means 123, respectively, and by the processing of these four means 120 to 123 and the object management means 102, (1) the monitoring task 20,
Registration of an object such as operation task 21 in the computer system, (2) deletion of the object from the computer system,
Four functions of (3) copying an object from a computer system to a computer system and (4) moving an object from a computer system to a computer system are realized. The object operating mechanism 105B of the other computer system 6A2 also has the object registration means 120B.
B, an object deleting unit 121B, an object transmitting unit 122B, and an object receiving unit 123B.

First, the object registration function will be described.

The object registration means 120 previously holds object execution module information (information having a program module including an object name and a path (Path)) shown in FIG.

At this time, when a request for registering a new object in the own computer system 6A1 is specified, for example, on the own computer system 6A1, the registration request is received via the message receiving means 103 and the destination object registration means is received. 120.

The object registration means 120 receives the transferred object registration request (FIG. 24, step S).
70), it is determined whether or not the requested object exists by referring to the object execution module information (step S71). If the result of this determination is that there is no request object (NO in step S71), the process ends.

On the other hand, when the requested object exists in the object execution module information (YES in the judgment in step S71), the object is generated, additionally registered in the object management means 102, and the processing is ended (step S72). ).

The generation of an object is realized using, for example, fork () and exec () functions which are UNIX system functions. The registration result is sent to the request source (the own computer system 6A1) as required by the message transmitting means 1.
04 may be transmitted. That is, when the object generation is successful, the message data indicating “success” is used. When the request object does not exist in the object execution module information, or when the activation of the object fails, the message data indicating “failure” is used. Is transmitted to the request source via the message transmission means 104.

Here, the object registration request source (computer system) and the computer system that executes registration are as follows.
It is not necessary to limit to the same computer system, and it is possible to operate the object registration means of another computer system. In that case, an object registration request is made to the object registration means on the computer system to be registered and registered in the object management means on the computer system, and the result is the request source as necessary. A reply is sent to another computer system.

Next, the object deletion function will be described.

When a request to delete the specified object on the own computer system 6A1 is received via the message receiving means 103 and transferred to the object deleting means 121 as the destination, the object deleting means 12
1 receives the object deletion request (FIG. 25, step S80), and determines whether or not there is an object to be deleted by referring to the object management means 102 (step S81). If the result of this determination is that there is no object to be deleted (NO in step S81), the process ends.

On the other hand, if an object to be deleted exists in the object management means 102 (YES in the judgment in step S81), the object is deleted from the object management means 102 and the processing is terminated (step S82). The deletion of the object is performed, for example, by UNI.
It can be realized using a kill () function, which is a system function on X, or the like.

The result of the deletion is transmitted to the request source (the own computer system 6A1) as necessary.
May be transmitted via the Internet. That is, when the object deletion is successful, the message data indicating “success” is sent to the message transmitting unit 104 when the request object does not exist or when the object deletion fails. The request is sent to the requester via the.

Here, the object deletion request source (computer system) and the computer system that executes registration are:
It is not necessary to limit to the same computer system, and it is possible to operate the object registration means of another computer system. In that case, an object deletion request is made to the object deletion means on the computer system to be deleted and registered in the object management means on the computer system, and the result is the request source as necessary. A reply is sent to another computer system.

Next, the object copy function will be described. This function is to generate a copy of a certain object on another computer system 6A2, and it is possible to dynamically change the multiplicity of an object.

When a request for copying an object on another computer system 6A2 is sent to the computer system 6A1 in which the object to be copied exists, the copy request is sent to the message receiving means 103 of the computer system 6A1. Received through. The copy request message includes at least an index indicating that the request is a copy request, a target object name, and information for specifying a copy destination computer system. It is also possible to add information for specifying the copy source computer system, but if not specified, the computer system where the target object exists is the copy source computer system.

When the copy request is transferred, the object transmitting means 122 receives the copy request (FIG. 26,
Step S90), referring to the object management means 102, the object to be copied is determined by the computer system 6A1.
It is determined whether it exists in the (copy source computer system 6A1) (step S91).

If the result of this determination is that the copy target object does not exist in the computer system 6A1 (NO in step S91), the process ends.

On the other hand, if an object to be copied exists in the object management means 102 (step S91)
The result of the determination is YES), and information relating to the object (for example, binary (binary) information of a program module corresponding to the target object, a source file, or the like) is specified via the message transmission unit 104 in the copy destination computer system 6A2. The message is transmitted to the message receiving unit 103B of the configuration management unit 100B (step S9).
2).

The transmitted copy object information is stored in the message receiving means 1 of another computer system 6A2.
The data is transferred to the object receiving unit 123B via the server 03B. The object receiving unit 123B generates an object based on the transferred copy target object information (step S93), registers the generated object in the object management unit 102B via the object registration unit 120B, and ends the processing (step S93). Step S
94).

The object can be generated by, for example, copying binary information, using a fork () function or exec () function, which is a system function on UNIX, and copying a source file. After compiling and converting it to an executable form,
It can be realized using an rk () function, an exec () function, or the like. The status at the end of the copy is returned to the copy source (computer system 6A1) via the message transmission means 104B as necessary.

Finally, the object moving function will be described. This function is used to move an object operating on one computer system or an object mounted in the same computer system to another computer system, and realizes a uniform load among a plurality of computer systems. Things.

When a request for moving the target object on another computer system 6A2 is transmitted to the computer system 6A1 in which the target object exists, the request for moving is sent to the message receiving means 103 of the computer system 6A1. Received through. The move request message includes at least an index indicating a move request, a target object name, information for specifying a destination computer system, and the like. It is also possible to add information for specifying the source computer system, but if not specified, the computer system where the target object exists is the source computer system.

When the transfer request is transferred, the object transmitting means 122 receives the transfer request (step S100 in FIG. 27), and refers to the object management means 102 to determine whether the transfer target object is the own computer system 6A1 (the transfer source). It is determined whether or not it exists in the computer system 6A1) (step S101).

If the result of this determination is that the object to be moved does not exist in the computer system 6A1 (NO in the determination in step S101), the processing ends.

On the other hand, if the object to be moved exists in the object management means 102 (step S101)
The result of the determination is YES), information on the object (for example, binary (binary) information of the program module corresponding to the target object, a source file, etc.) is transferred to the destination computer system 6A2 designated via the message transmitting means 104. The message is transmitted to the message receiving unit 103B of the configuration management unit 100B (step S10).
2) The target object is deleted from the object management means 102 via the object deletion means 121 (step S103).

On the other hand, the transmitted object information to be moved is transferred to the object receiving means 123B via the message receiving means 103B of another computer system 6A2. The object receiving unit 123B generates an object based on the transferred target object information (step S104), registers the generated object in the object management unit 102B via the object registration unit 120B, and ends the processing. (Step S105).

The object can be generated, for example, by moving binary information, by using a fork () function or exec () function, which is a system function on UNIX, and by moving a source file. After compiling and converting it to an executable format,
It can be realized using a k () function, an exec () function, or the like. The state at the end of the transfer is returned to the transfer source (computer system 6A1) via the message transmission means 104B as necessary.

Note that the object registration, object deletion, object copy, and object movement of the object operation mechanism described above are performed on one object, but the objects are grouped.
It is also possible to register, delete, copy, and move the group at once. When the object operation is performed in units of groups, a method of describing all the objects belonging to the group in each operation request message, the object management unit 102,
This can be realized by registering not only individual object names but also object groups at 102B and specifying the group name for operation.

As described in detail above, by the processing of the object operating mechanisms 105 and 105B of this configuration, for example, an object operating on a faulty computer system after a fault has occurred can be registered on another computer system, and the load can be reduced. The power system monitoring and control system has high reliability because it is possible to move objects in order to achieve equality, and to easily copy objects to achieve object multiplexing in order to achieve high reliability. Can be provided.

Further, the configuration management units 100A and 100B for performing the object detection such as the failure detection in the computer system and the object unit and the object operation such as object registration, deletion, copy, and movement are independent of the business application (program) such as the business object. Therefore, the business application can be changed independently of the contents of the configuration management units 100A and 100B, and the configuration management units 100A and 100B can be changed independently.
00B can be changed without depending on the business application.

Next, in the power system monitoring and control system, when the occurrence of a failure in at least one of the plurality of computer systems constituting a certain business establishment is detected by the above configuration management unit, the failure is detected. Means for specifically realizing the processing of backing up the processing of the computer system will be described.

In FIG. 28, an office (for example, substation 6)
Each of the computer systems 6A1 to 6A3 of the plurality of computer systems 6A1 to 6A5 constituting the CPU a) has a CPU.
It has failure recovery units 130A1 to 130A3, which are function realizing means of the abnormal failure management subsystem 35 embodied by processes such as 6a1 to 6a3.

The computer system 6A4 includes a configuration management unit 100A and a plurality of business applications (business objects, such as a substation monitoring business application and an operation business application) stored in the memory 6c3 and embodied by the processing of the CPU 6a1 and the like. (Shown as object A and object B in the figure) 23
And

Further, the computer system 6A5 includes the configuration management unit 100B described above. Descriptions and illustrations of other business applications, subsystems, and platforms in the substation 6a are omitted.

Failure recovery units 130A1 to 130A3
(Hereinafter, the failure recovery unit 130A1 will be described as a representative.) The message receiving unit 131 that receives the failure occurrence command (failure occurrence message) sent from the configuration management unit 100B of the computer system 6A5, and the own computer system 6A1 A backup information holding unit 132 holds a computer system name capable of backing up the process (object) when a failure occurs.

In the case of this configuration, the backup information holding means 132 holds at least the computer system 6A4.

The backup information holding means 132 is referred to based on the failure occurrence message received by the message receiving means 131, and it is determined whether or not the own computer system 6A1 backs up the failed computer system (6A4). Backup determination means 13 that outputs a backup command only when performing backup
3, backup object holding means 134 for holding all object names mounted on all computer systems that can be backed up and program module names corresponding to the object names, and mounted on all computer systems that can be backed up The same object group as the object group is held for each computer system as a backup object group, and the program module name of the object to be backed up is obtained according to the held contents of the backup object holding means 134, and the required object is stored in, for example, UNIX. And a backup object registering means 135 for generating, registering, and activating the fork () and exec () functions, which are system functions.

Backup object registration means 135
As shown in FIG. 29, the backup-capable computer system 6A4 and the same backup object group (for example, object A and object B) as the object group mounted on the computer system 6A4, the backup-capable computer system 6An and the computer system 6An The same backup object group (for example, object A, object C) as the object group mounted on the
1 and the same backup object group as the object group mounted on the computer system 6An + 1 (for example, object A, object B, object C)
Holding.

As shown in FIG. 30, the backup object holding means 134 includes an object group (for example, object A, object B, object C) mounted on all the backup-capable computer systems and the object group (object A, Program modules (/usr/object/object-A.exe, / usr / objec) corresponding to each of the objects B and C
t / object-B.exe, /usr/object/object-C.exe).

[0239] Note that the other failure recovery units 130A1,
The configuration of the failure recovery unit 130A1 is also substantially the same as that of the failure recovery unit 130A1 (the storage contents of the backup information storage unit 132, backup object storage unit 134, and backup object registration unit are different).

According to this configuration, an Alive message is periodically transmitted from the computer system 6A4 operating a process (business) based on the objects A and B to the configuration management unit 100B of the computer system 6A5.

At this time, if the reception time of the Alive message sent to the configuration management unit 100B of the computer system 6A5 has passed a predetermined time or more from the current time, the above-described processing of the computer failure detection means 110B of the configuration management unit 100B causes It is determined that a failure has occurred in the computer system 6A4, and the failure recovery units 130A1 to 130A3 of the computer systems 6A1 to 6A3 other than the computer system 6A4 have the same failure.
The failure message of A4 is sent to the configuration management unit 100B.
Automatically transmitted via the message transmission means 104B. The transmitted failure occurrence message is received via the message receiving means 131 and the backup determination means 1
33.

The backup determining means 133 refers to the backup information holding means 132 based on the transmitted failure occurrence message, and determines whether the own computer system 6A1 backs up the faulty computer system 6A4.

Now, since the backup information holding means 132 holds the computer system 6A4 as the backup computer system name, a backup command is sent from the backup judgment means 133 to the backup object registration means 135.

Backup object registration means 135
In the above, a backup object group (object A, object B) corresponding to the failure computer system 6A4 is obtained in accordance with the transmitted backup command. Further, backup object registration means 135
The backup object holding means 13
4 is referenced and the program modules corresponding to the objects A and B (/usr/object/object-A.ex
e, /usr/object/object-B.exe).

Then, the obtained program modules (/usr/object/object-A.exe, / usr / object / object-Be
xe) based on the backup object registration means 13
5, the objects A and B are registered and restarted on the computer system 6A1.

As described above, according to this configuration, the objects A and B operating on the faulty computer system 6A4 are restarted on the other computer system 6A1, and the objects A and B are restarted.
Business processing based on the information can be continuously performed.

The failure recovery units 130A1 to 130A13
By rewriting the contents held by the backup information holding means 132 and the backup object registration means 135 of 0A3, a highly flexible and inexpensive backup configuration can be realized without fixing and using the standby computer system.

(Second Embodiment) FIG. 31 shows an example of the development of the power system monitoring and control system described in the first embodiment, such as the object @ business application (monitoring business, operation business, etc.) FIG. 1 is a block diagram showing a schematic configuration of a power system monitoring and control system in which a system (system information model, operation information model, etc.) is multiplexed over a wide range beyond the framework of a business establishment. Note that, in the present embodiment, a description will be given of, as an example, a western power dispatching center (western office 140A), which is a main power dispatching station, and an eastern power dispatching station (eastern office 140B), which is a main power dispatching center. Further, the hardware (see FIG. 2) of each office and the function of each object (see FIG. 4) are the same as those in the first embodiment, and therefore, description thereof will be omitted below unless otherwise specified.

[0249] The western office 140A has a plurality (3 in the figure).
) Computer systems 4A1 to 4A3. The computer systems 4A1 to 4A3 are equipped with the business applications and subsystems described in the first embodiment.

That is, in the computer system 4A1 of the western office 140A, the monitoring business object (western monitoring)

On the other hand, the computer system 4A1 includes an object for multiplexing the western operation object 21 (the standby operation object 21 waits while the western operation object 21 is performing a predetermined function, and the western operation object 21 fails. In this case, a standby system western operation object 21W is stored in, for example, an external memory area of the memory 4c1 in the standby state (also referred to as a standby state) as a standby system object that takes over the processing.

In the case where the standby system western operation object 21W is stored in the external memory area, the standby system western operation object 21W in the standby state is loaded into the internal memory area when the western operation object 21 fails. Thereafter, the operation processing is continuously performed.

In the computer system 4A2, a standby monitor object 20W is stored in a spare state, for example, in an external memory area of the memory 4c2 as the multiplex object for the western monitor object 20.

Further, in the computer system 4A3, the standby monitoring object 20W is stored in the external memory area or the like in the memory 4c3 as a standby object for the western monitoring object 20, for example, in a standby state.

Similarly to the west office 140A, the east office 140B has a plurality (three in the figure) of computer systems 4.
A4, 4A5, and the computer system 4A4
, 4A5 are equipped with the business application and subsystem described in the first embodiment. The computer systems 4A1 and 4A2 of the western office 140A and the computer system 4A4 of the eastern office 140B are located in the same location L1, and the computer system 4A3 of the western office 140A and the computer system 4A5 of the eastern office 140B have the same computer system. It is located at location L2.

That is, in the computer system 4A4 of the eastern office 140B, the configuration management subsystem 36, the fault management subsystem 35 and the system information model 30 are loaded as operating objects into the internal memory area of the memory 4c4. Further, as a multiplexed object for the eastern monitoring object 20B described later,
The standby eastern monitoring object 20BW is, for example, a memory 4
