And when the power failure notification or the recovery notification is received from each power meter 2, the power failure information management device 5 is identified as the power failure notification or the recovery notification with the date and time when the receiving point identification number is specified and the power failure has occurred or has been recovered. Send.

  The distribution automation equipment 4 has functions such as distribution system monitoring and switch control. When a power failure occurs, the distribution automation facility 4 identifies the location of the accident that caused the power failure and distributes power to distribution lines other than the accident section. It is a system having information including a power outage section of an electric wire. And if a power failure and its recovery are detected, the information (power failure notification or recovery notification) including the fact, the section, and the date and time is transmitted to the power failure information management device 5.

  The power failure information management device 5 is a device that manages (generates, updates, etc.) information related to the power failure of each customer C based on the detection results of each power meter 2 and distribution automation equipment 4, and is configured by a server or a computer. ing. That is, the relationship between the identification information (customer ID 711 described later) of each customer C and the meter number of the power meter 2 installed in this customer C, the relationship between each customer C and the power supply network (which Which customer C is connected to the distribution line). Here, the customer C includes not only the customer C contracted with the first power company P1, but also all the customers C located in the power supply network of the first power company P1. For this reason, even if the customer C who has contracted with the power companies P2 and P3 other than the first power company P1 has a power failure, the power failure of the customer C can be detected and understood.

  Then, when a power failure notification or recovery notification is received from each power meter 2 via the meter management device 3, the identification information of the corresponding customer C, the power failure date and time, the recovery date and time, and the power meter 2 detects a power failure or recovery. Registration information including the fact that it has been recorded is generated, stored, and transmitted to the sharing device 7. Similarly, when a power failure notification or recovery notification is received from the distribution automation facility 4, the customer C included in the received section is determined, the identification information of each determined customer C, the power failure date and time, the recovery date, and the distribution automation facility. 4, registration information including that a power failure or recovery has been detected is generated, stored, and transmitted to the sharing device 7. Thus, the power failure information management device 5 includes, in the information regarding power failure, whether each power meter 2 has detected a power failure or recovery, or whether the power distribution automation facility 4 has detected a power failure or recovery.

  The information providing device 6 is a device that provides various types of information to each customer C, is configured by a server and a computer, and includes information related to a power outage as information to be provided. That is, when the customer C provides a website that the customer C accesses, and the customer C accesses the website and performs a predetermined operation, information on the power failure of the customer C is obtained in cooperation with the sharing device 7 described later. provide. Moreover, the mail address of the customer C who wishes to distribute information related to the power failure is stored in advance, the sharing device 7 is accessed periodically, and information related to the power failure (power failure information 716 described later) is registered and updated. Information about the power failure is transmitted to the mail address of the customer C. For example, a power outage mail including the contents of an occurrence date and time 716b and a power outage type 716d, which will be described later, and a recovery mail including the contents of the recovery date and time 716e are transmitted. Further, the customer C who has transmitted information related to the power failure by e-mail is stored in the “notification mail transmission customer list” referred to by the person in charge at the customer center in order to respond to the inquiry from the customer C.

  The shared device 7 is a device that stores information managed by the power failure information management device 5, and is configured by a server or a computer. That is, in this embodiment, when the information about the power failure, that is, the registration information is received from the power failure information management device 5, the shared information database 71 as shown in FIG. To do. On the other hand, the share information 7 may be accessed from the power failure information management device 5 and the registration information may be updated and stored in the share information database 71.

  In the shared information database 71, contract number 712, customer name 713, location 714, meter number 715, power failure information 716, and others 717 are stored for each customer ID 711. The customer ID 711 stores identification information for identifying the customer C, and this identification information includes information indicating which power company is contracted. The contract number 712 stores information for identifying a contract with the contracted power company, and the customer name 713 stores the name of the customer C. The location 714 stores the location of the customer C, and the meter number 715 stores the meter number of the power meter 2 installed in the customer C.

  The power failure information 716 is registered and stored every time the registration information is received from the power failure information management device 5, and is registered and stored in the power failure information 716 of the customer ID 711 corresponding to the identification information of the customer C included in the registration information. . That is, for each power failure ID 716a, an occurrence date and time 716b, an occurrence flag 716c, a power failure type 716d, a recovery date and time 716e, a recovery flag 716f, and the like are stored.

  The power failure ID 716a stores information for identifying a power failure, and is generated and stored every time a new power failure occurs and new power failure information 716 is generated. The occurrence date and time 716b stores the date and time of the outage included in the registration information from the outage information management device 5, and the occurrence flag 716c stores whether or not a power outage is detected by the power meter 2 or the distribution automation equipment 4 is detected. Is done. That is, when the registration information includes the fact that the power meter 2 has been detected, “1” is stored, and the registration information includes the fact that the power distribution automation facility 4 has detected the power failure. In this case, “2” is stored. Therefore, when both the registration information indicating that the power meter 2 has detected the power failure and the registration information indicating that the power distribution automation facility 4 has detected the power failure, “1” and “2” are stored. The

  The power failure type 716d stores whether the power failure is a power failure due to a high-voltage distribution line or a low-voltage power failure (a power failure due to a transformer failure, disconnection of a low-voltage line or a lead-in line). That is, when “2” is stored in the generation flag 716c (normally “1” is also stored in this case), it is stored as a power failure due to the high-voltage distribution line, and only “1” is stored in the generation flag 716c. If it is, it is stored as a low voltage power outage.

  The restoration date and time 716e stores the restoration date and time included in the registration information from the power failure information management device 5, and the restoration flag 716f stores whether the restoration is detected by the power meter 2 or the restoration automation facility 4 Is done. That is, when the registration information includes the fact that the restoration has been detected by the power meter 2, “1” is stored, and the registration information includes the fact that the restoration is detected by the distribution automation equipment 4. In this case, “2” is stored. Therefore, when both the registration information that the power meter 2 detects the recovery and the registration information that the power distribution automation facility 4 detects the recovery are received, “1” and “2” are stored. The

  And with this restoration flag 716f, it can be confirmed whether or not the customer C has been properly restored. That is, for example, when a power failure occurs due to a high-voltage distribution line and “1” and “2” are stored in the recovery flag 716f, it can be confirmed that the customer C has recovered properly, and the recovery flag 716f indicates “ When only “2” is stored, it can be confirmed that the customer C is not properly restored.

  In this embodiment, the shared information database 71 has such a data configuration, but may have other data configurations or other data storage methods. For example, the power failure information management device 5 generates and stores the shared information database 71 shown in FIG. 3 and stores the data (only data necessary for providing information to the information acquisition device 8 or the like) each time the data is registered and updated. You may make it memorize | store in the shared apparatus 7. FIG.

  The information acquisition device 8 is a device that can acquire information stored in the shared device 7 and is configured by a server or a computer. That is, it is connected to the shared device 7 so as to be able to communicate, and can access the shared device 7 to read data in the shared information database 71.

  Next, the operation of the power failure information providing system 1 having such a configuration will be described.

  First, as shown in FIG. 4, for example, when a power failure occurs in the distribution line of the first power company P <b> 1 (step S <b> 1), the power distribution automation facility 4 detects the power failure and transmits a power failure notification to the power failure information management device 5. (Step S2). Similarly, for example, when a power failure occurs in a low-voltage line or a lead-in line (step S3), a power failure is detected in each power meter 2 and a power failure notification is transmitted to the meter management device 3 (step S4). A power failure notification is transmitted from the power failure information management device 5 to the power failure information management device 5 (step S5).

  Next, based on the power failure notification / detection result received in the power failure information management device 5, information related to the power failure of each customer C is generated and updated, and the registration information as described above is transmitted to the sharing device 7 (step). S6). In response to this, the power failure information 716 of the shared information database 71 is registered in the shared device 7 based on the registered information.

  Subsequently, the information providing device 6 periodically accesses the sharing device 7 (step S7), and a power failure mail is transmitted to the customer C who desires information distribution (step S8). Further, the information in the shared information database 71 is acquired by accessing the shared device 7 from the information acquiring device 8 of the second electric power companies P2 and P3 (step S9).

  Also, as shown in FIG. 5, for example, when a power failure that occurred in the distribution line of the first power company P1 is restored (step S11), the restoration is detected by the distribution automation equipment 4, and the restoration notification is sent to the power failure information management device 5 (Step S12). Similarly, for example, when a power failure that occurred in the low voltage line or the lead-in line of the first electric power company P1 is restored (step S13), restoration is detected by each power meter 2, and a restoration notice is transmitted to the meter management device 3 (step S13). S14) Further, a recovery notification is transmitted from the meter management device 3 to the power failure information management device 5 (step S15).

  Next, based on the recovery notification / detection result received by the power failure information management device 5, the information regarding the power failure of each customer C is updated, and the registration information as described above is transmitted to the sharing device 7 (step S16). . In response to this, the power failure information 716 in the shared information database 71 is updated in the shared device 7 based on the registration information.

  Subsequently, the information providing device 6 periodically accesses the sharing device 7 (step S17), and a recovery mail is transmitted to the customer C who desires information distribution (step S18). Further, the information in the shared information database 71 is acquired by accessing the shared device 7 from the information acquiring device 8 of the second electric power companies P2 and P3 (step S19).

  Thus, according to this power failure information providing system 1, when a power failure occurs in the power supply network of the first power company P1, information related to the power failure of each customer C is stored in the shared device 7, and this shared device 7 can be acquired by the second power companies P2 and P3. That is, since the information regarding the power failure that occurred at a certain power company P1 can be obtained by the other power companies P2 and P3, it is possible to improve the service to the customer C and the like.

  For example, a customer C1 who resides in the power supply network of the first power company P1 has a contract with a second power company (new power company) P2, and the second power company P2 has a contract with the first power company P1. Suppose you are using the power supply network. And when a power failure occurs in the power supply network of the first power company P1, the second power company P2 can acquire information related to the power failure of the customer C1, so that the second power company P2 becomes the consumer C1. Accordingly, it is possible to respond appropriately and promptly and to reduce the burden on the first electric power company P1. In addition, for example, when a power failure occurs near the boundary between the adjacent power companies P1 and P2, the power companies P1 and P2 can both know information about the power failure, so that recovery work can be performed in cooperation with each other. Appropriate and quick response is possible.

  Moreover, since the power failure is detected not only by the distribution automation equipment 4 but also by the monitoring unit 23 of each power meter 2, not only the power failure of the high-voltage distribution line but also the low-voltage power failure (transformer failure, disconnection of the low-voltage line or service line, etc.) (Power failure) can also be detected. For this reason, it becomes possible to improve the service to the consumer C more.

  Furthermore, whether the power failure has been detected by the monitoring unit 23 of the power meter 2 or whether the power failure has been detected by the distribution automation equipment 4 (occurrence flag 716c) is stored in the shared device 7 as information about the power failure, The type 716d) can be obtained, and as a result, it is possible to appropriately and quickly respond to the customer C and recover.

  Further, the restoration of the power failure in the power supply network is also detected, and based on the detection result, the restoration is stored in the shared device 7 as information on the power failure. For this reason, the second power companies P2, P3, etc. can also know that the power failure has been restored at each customer C, and the service to the customer C can be further improved.
