PROBLEM TO BE SOLVED: To maintain a power system in stable voltage by judging the bus that a transformer is connected, from the opening and closing information of a switch stored in a switch information storage part, and selecting a transformer which does not fall in single-bus supply by stop operation. SOLUTION: When a remote monitor 3 remote-controls the facilities of a power system, if a transformer economic operation means 6-1 provided at an electronic computer 4 is started, it judges the economical efficiency of the transformer first, with the joint use stop power flow set value as the criteria of judgment, and judges whether to stop the transformer in operation or not from the result. When it is judged that the stop operation should be performed, this judges the system bus where the transformer is connected, by the opening and closing condition of the switch of the transformer 2 stored in a V-shaped transformer storage 5-1, and judges whether it is biased to the bus connection on one side or not. Next, this decides the machine of No. to stop operation, giving priority to the machine of No. where the number of times of operation stop is smaller, and performs the stop operation, and finishes the processing. |
