When all status change data (hereinafter referred to as status change data) of system information (switches, protection relays) due to the effects of the accident are input to the computer, power outage equipment judgment and accident equipment judgment are performed, and the power outage system due to the accident is restored In this method, a process for creating an operation command procedure for starting the operation is started, and a restoration method that has the same system configuration as the system before the accident with respect to the power failure system after the accident is determined. For this purpose, it is necessary to save the current system state data immediately before reflecting the state change data of the system information determined to be an accident. In the following description,
The stored system status data immediately before the accident is referred to as a pre-accident system.

る。However, if accidents occur simultaneously or consecutively at multiple facilities, the recovery process for the preceding accident that is being executed at the time of detection of the subsequent new accident is stopped, and the system restarts from the pre-accident system saving process. Then, a process of deciding a recovery method for the preceding accident and the new accident collectively is performed.

Preparation operation is performed), and the inside of the power failure system is in a finely divided state. For this reason, simply preserving in the system immediately before the occurrence of the accident may not be able to use the pre-accident system at the time of the new accident as the pre-accident system state that is the basis of the recovery form for the preceding accident . Therefore, when an accident occurs in a plurality of facilities consecutively, there is a problem that the restoration mode of the power failure system for the preceding accident has a different system configuration from the operation mode before the preceding accident.

定処理を行なう。Hereinafter, this point will be described in detail with reference to FIG. First
The figure is a model system diagram showing the state of the system when an accident occurs. In the figure, the transmission line Accident As a result, the switches a and b at both ends of the switch are opened, and the system-1 loses power. Inside the power-failed system-1, an opening operation of the switches c and d is performed as a recovery preparation operation. In parallel with this, a computer system (not shown) performs an accident recovery method determination process.

ある。During the process, the transmission line Accident When the error occurs, the processing for the power outage system-1 being executed is stopped, and the processing is performed again from the creation of the pre-accident system state. At this time, the switches c and d in the blackout system-1 are open, so the Assembled from the recreated pre-accident system state
Before the accident, the transmission line It is not possible to determine whether or not power has been received from the Internet.

要する時間が「大」となり現実的ではない。Therefore, in order to eliminate such problems, it is necessary to prepare a storage area for the pre-accident system for each accident occurrence unit, search for the pre-accident system corresponding to the accident at the time of recovery operation processing, and perform individual processing for each. Although it is possible to recover to the previous operation mode, considering the case where multiple accidents occur consecutively, the processing area is complicated because the storage area becomes enormous, and the area referenced for each accident is different. From these problems, and from these problems, the time required for the recovery method determination processing becomes "large", which is not realistic.

する。First, state change data such as a switch such as a circuit breaker and a protection relay at each of the substations 1 to n in the power system 1 is transmitted from the integrated control station computer system to the first and second data collection and distribution devices.
The information is input to the automatic recovery computer system 6 at the time of the accident via the traditional device 4. In the automatic recovery computer system 6 in the event of inputting the state change data, the current system status data used for various online processes such as the analysis of the accident and the CRT display are updated in the step 61, and in the step S62 for the subsequent processes. The state change data is classified into the following three types by analysis.
作業停止操作、運用操作による状変データ。 Status change data by work stop operation and operation operation.

更新する。If an accident in the power system is detected from the status change data (step S64), the system status data before the accident, that is, the system status before the accident is copied to another file, and the system status before the accident for accident recovery is stepped.
In addition to the creation in S65, the processing mode is set to the “during accident” mode in step S66. In step S63, it is determined whether or not the processing mode of the computer is in an accident during the processing of the subsequently input state change data, and the state change data obtained by the recovery preparation operation of the above classification during the accident is removed (step S67). In step 68, the pre-accident system status data for accident recovery is updated with the data.

First, in the model system shown in FIG. Accident If the transmission line The switches a and b at both ends of the switch trip, and the system-1 loses power. Then, in this blackout system, the switch
c and d are released on site as a recovery preparation operation, and the computer system determines the recovery method of the power failure system-1. New accident during execution of the process If a precedence accident occurs Transmission line as well The switches e and f at both ends of the switch trip, and the system-2 loses power. This new accident In order to determine the restoration method in consideration of the balance of the entire system at the time of detection of, the processing for the power failure system-1 is stopped, and a method of collectively restoring the power failure system-1 and the power failure system-2 is determined. At this time, the switches c and d of the power failure system-1 are in the open state in the modern system state data.
Switches c and d remain closed (FIG. 4). From this, by using the pre-accident system status data for accident restoration, the restoration method for the power failure system-1 to the pre-accident operation mode is a new accident. Can be determined without being affected by Therefore,
By using such pre-accident system status data for accident recovery, even when a plurality of accidents occur, it is possible to easily restore to the operation mode before the accident, which is the basis of the restoration mode.
