POWER MONITORING CONTROL SYSTEM, AND METHOD OF TAKING OVER REMOTE MONITORING CONTROLLER

摘要

PROBLEM TO BE SOLVED: To smoothly take over the contents of control to the other monitoring control server when the monitoring control server in a control mode is stopped.

SOLUTION: A power system monitoring control system includes: a monitoring control server 30; a first TC 10 which controls power transformer equipment by transmitting and receiving control signals 53 to and from the monitoring control server 30 via a wide area network 40; and a second TC 20 which controls the power transformer equipment when the first TC 10 fails and stops. The control signals 53 include: an instruction signal 53a which is used by the monitoring control server 30 to instruct a control process to the first TC 10; and an instruction response signal 53b which is used to notify the result in response to instruction of the instruction signal 53a. A second TC 20 can detect the control signal 53, which is transmitted or received by the first TC 10 just before the first TC 10 stops. Thus, control can be implemented via a process based on the next control signal 53 scheduled to be transmitted or received by the first TC 10.
