First, the system failure processing means 2-1 inputs information on the power system status from the information input device @1, and determines whether the switch and relay statuses have changed from before. If this condition is different from before and the changed combination of switch and relay matches, it is determined that an accident has occurred.

For example, the CB of a power transmission line changes from ON to OFF, and the HG (ground protection) relay of the same transmission line turns OFF.
If the switch changes from to ON, it is determined that a power line ground fault has occurred. When it is determined that an accident has occurred, predetermined information is stored in the accident information storage means 2-2.The configuration of the accident information storage means 2-2 is shown in FIG.
-3,5n-3), the date of the accident (51-1,5n-)
1) , Accident occurrence time (51-2, 5n-2), Electrical disconnection display X coordinate (51-4, 5n-4), Electrical place name display Y coordinate (51-5, 5n-5) columns. is provided.

Therefore, when it is determined that an accident has occurred, if the name of the electrical plant is not included in the electrical plant where the accident occurred in the accident information storage means 2-2, the current date, time and name of the electrical plant are stored, and the accident core breakage is displayed. Activate means 2-3 (FIG. 2, steps 21.22.
23.24.25.26).

The electrical station where the accident occurred is the electrical station where the switchgear was damaged. The accident breakage display means 2-3 displays information from the accident information storage means 2-2 in the order of accident occurrence (
51-3.5n-3) and output it to the CR7 display device 3-1.

．． 32.33).

FIG. 6 is a display example of the electrical stations where the accident occurred are displayed on the CR7 display device 3-1, and the electrical stations where the accident occurred 61 to 69 are displayed in the order of accident occurrence.

For example, when two pieces of accident information are registered in the accident information storage means 2-2, the electrical stations are displayed in the accident occurring electrical disconnection display sections 61 and 62 in the order in which the accidents occurred.

This makes it possible to make the operator aware of the occurrence of a system accident.

Also, as is clear from Fig. 6, the accidental breakage display means 2-3
outputs only the electrical disconnection caused by the accident to the CRT display device 3-1, so no matter what kind of screen is displayed on the screen display section 60 in FIG.
It is possible to display the accidental electrical disconnection.

Next, the display of the system diagram screen showing the details of the system accident will be explained. In order to learn the details of the system accident, the operator
The accidental electrical breakage 61 to 69 shown in the figure is
Instruct with 2. With this instruction, the accident flight number receiving means 2-4 is activated, and this accident flight number receiving means 2-4 is used to determine which of the electric breaks 61 to 69 in which the accident occurred was instructed by the light ben. , the light ben indicated X and Y coordinates are input, and the light ben indicated X and Y coordinates and the electrical breakage display X coordinate of the accident information storage means 2-2 (Fig.
4.5n-4), electric station name display Y coordinate (Figure 5 51-5)
．． 5n-5) coincides with the accidental electrical disconnection (Fig. 5 51)
-3.5n-3) and delete its violation and corresponding accident information (Figure 5, 51.5n).

Next, the accidental electrical disconnection 61 on the CRT display device 3-1
69, the accident breakage display means 2-3 is activated, and in order to display a system diagram representing the accident state on the CRT display device 3-1, a screen number is determined based on the instructed electrical breakage. , notifies this screen number to the screen display means 2-5 (
