DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. In FIG.
26 is a state change detecting means, 27 is a data storing means, 34
Is stored data, and 35 is data transmission means.

Next, the operation will be described. FIG. 2 is a flowchart illustrating a method in which the protection control device detects a state change. (1) First, in S11, it is determined whether the protection control device 1 operates by the state change detecting means 26 or an abnormality of its own device has occurred by the automatic monitoring function. (2) If there is a state change, the process proceeds to S12, Detailed contents of the state change when the state change occurs by the data storage means (state change information such as the time of occurrence, operation of the apparatus, and abnormality of the apparatus), and the operation state of the apparatus (device setting, input state, output state, etc.) ) Is stored for a certain period of time before or after the occurrence of the state change.

(3) Next, proceeding to S13, it is determined whether or not the data saving is completed. (4) If the data saving is completed, proceeding to S14, the data is transmitted to the predetermined terminal 3 by the data transmitting means 35. Automatically send a copy of the data.

(5) In the state change detection in S11, the determination operation is repeated until the state change is detected.
(6) Similarly, when it is determined in S13 that the data storage is not completed, the determination operation is repeated until the data storage is completed.
According to the above operation, the system operator has an effect that the state change has occurred from a predetermined terminal and the detailed contents thereof can be quickly grasped offline.

Embodiment 2 In the first embodiment, the case where the state change information or the operation state information is automatically transmitted to a predetermined terminal when the state change occurs has been described. However, as shown in FIG.
Destination setting means 33 that can arbitrarily set the destination and data transmission means 35 that copies stored data 34 storing state change information and operation state information to the destination set by the destination setting means 33 and transmits the data. By providing this, it is possible to transmit state change information and operation state information to any terminal.

As a result, for example, a plurality of system operators can grasp the state change information and the operation state information as common information, the contact time between the system operators can be shortened,
There is an effect that prompt response is possible.

Embodiment 3 FIG. In the first embodiment, the case where the state change information or the operation state information is automatically transmitted to a predetermined terminal when the state change occurs has been described. However, as shown in FIG. The transmission content is selected from the stored data by providing the transmission content selection unit 43 for selecting the transmission content from the state change content 41 and the transmission content definition 42 arbitrarily set by the input unit 31. .

Thus, it is possible to select and transmit the transmission content according to the content of the state change. For example,
If the transmission content definition defines that "when a relatively minor status change occurs, only the status change item name is transmitted", unnecessary transmission of large-capacity information is prevented. Can be done. Further, for example, if the transmission content definition is defined as "transmit analog information before and after the occurrence of a state change when a state change related to analog input occurs", the cause of the state change can be quickly investigated. There is.

Embodiment 4 In the first embodiment, the case where the state change information or the operation state information is automatically transmitted to a predetermined terminal when the state change occurs has been described. However, as shown in FIG. 5, when the state change is detected, The transmission destination is selected by providing a transmission destination selection unit 52 for selecting the transmission destination from the contents of the state change and the transmission destination definition 51 arbitrarily set by the input unit 31. Thereby, it becomes possible to select a transmission destination and transmit according to the content of the state change.

For example, by defining in the destination definition that "when a relatively important state change occurs, the state is transmitted to the substation and the power supply station", the cause of the same phenomenon can be identified and recovered at a plurality of locations. Work and the like can be handled. Also, for example, if the destination definition defines that “if the status change is related to the device error, send it to the terminal of the device manufacturer”, the cause of the device error can be investigated by the manufacturer, and the There is an effect that a restoring is possible.

Embodiment 5 In the first embodiment, the case where the state change information and the operation state information are automatically transmitted to a predetermined terminal when the state change occurs has been described.
As shown in FIG. 6, when a status change is detected, a destination selection means 5 for selecting a destination according to the content of the status change.
2 and transmission content selection means 43 for selecting the transmission content according to the status change content, so that the transmission content according to the status change content can be transmitted to the transmission destination according to the status change.

As a modification, a transmission destination selection means 52 for selecting a transmission destination according to the state change content, and a transmission content selection means 43 for selecting a transmission content according to the selected transmission destination
It may be. For example, even if the same state change occurs, it is possible to change the transmission item, transmission content, request item, and the like depending on the transmission destination.

Embodiment 6 FIG. In the first embodiment, the case where the state change information and the operation state information are automatically transmitted to a predetermined terminal when the state change occurs has been described.
As shown in FIG. 7, a file name generation unit 61 is provided to reflect the device name, the content of the state change, and the detected time from the stored data of the protection control device in the file name,
From the file name, the device that detected the status change and the detection time can be identified.

For example, the name of the protection control device that detected the status change is BP (bus protection relay) and the content of the status change is AF.
When the detection time is 10:35 due to (analog circuit failure), the name of the file to be automatically transmitted is, for example, "BP103
5AF ", the receiver can recognize the state change detection device, the detection content, and the detection time by the file name.

Also, when a state change is detected by a plurality of devices at the same time, or when a plurality of state changes are detected by the same device, each phenomenon can be managed with a different file name. In addition, it is possible to prevent the past data from being deleted due to duplicate file names.

[0031]

As described above, conventionally, when a status change occurs, only information for specifying the device operation or the device in which the device abnormality has occurred has been described. There is an effect that detailed information such as recording of the operation state of the device when a change occurs can be transmitted. Further, the transmission destination of the detailed information can be arbitrarily selected, and further, the transmission destination, the transmission content, or the transmission destination and the transmission content can be arbitrarily selected according to the content of the generated state change. There is an effect that the file contents can be grasped by the file name.
