Immediately after confirming the location, examine accident resolution methods and procedures, and contact the necessary locations and give instructions and supervision.

At the time of the alarm display test for each electric station, the monitoring control computer 111 receives the target electric power device (the electric station and electric power to be subjected to the alarm display test) from the _{first to third} consoles 113 _{1 to} 1133. When an alarm display test start instruction signal for the device) is sent, an operation signal in accordance with a predetermined alarm display test procedure (alarm display test sequence) for the target power device at the target electrical station is sent to the first to n-th operation signals. The data is transmitted to the remote monitoring control devices 120 _{1 to} 120 _n via the communication line 1.
For example, if there is a request for an alarm display test for the transformer # 2 installed in the first electric station shown in FIG. 7 from the first electric station, one of several duty staff (hereinafter, “ Is referred to as the "first duty person in charge of the electric power station"), using the _first console 1131, the alarm display test start instruction signal of the transformer # 2 of the first electric power station is sent to the monitoring control computer 111. The operation signal is transmitted to the first remote monitoring control device 120 ₁ via the communication line 1 according to the alarm display test procedure for the transformer # 2 of the first electric station.

Thus, for example, in order to perform an alarm display test at the time of the primary short circuit of the transformer # 2 of the first electric station, an operation signal for interrupting (opening) the primary circuit breakers 150 and 152 is received from the monitoring control computer 111. When through the communication line 1 and the first remote monitor control device 120 ₁ is transmitted to the overcurrent relay (51P) 160, 1 primary breaker 150, 152 is blocked by the overcurrent relay 160, the overcurrent relay 160 device data indicating, for example, the operation contents and state (first device data) is transmitted to the monitoring control computer 111 from the over current relay 160 via the first remote monitor control device 120 ₁ and the communication line 1.

  As a result, the supervisory control computer 111 displays the transformer # 2 (accident occurrence location) of the first electric station in the system monitoring panel 112 so as to be distinguished from the others, and the bell BL of the system monitoring panel 112 is sounded. The duty person in charge of the first electric power station can confirm that the alarm display test result of the primary short circuit of the transformer # 2 of the first electric power station is normal.
