PROBLEM TO BE SOLVED: To provide a transformer reverse power flow control system capable of taking a reverse power flow countermeasure without using a battery.SOLUTION: When reverse power flow generation on the secondary of a second A transformer Tris detected by a reverse power flow generation monitoring unit 12, a bank shift control unit 16 performs bank shift operation on conditions that a Tr overload examination unit 13 determined that "an overload is not generated in the first A transformer Tr(shift side transformer)" based on the first and second bus loads x, yand the first A transformer rated capacity X, and that the voltage variation ΔV calculated by a ΔV calculation unit 14, based on the first and second bus voltage values V, Vand the first and second reactive power values Q, Qis in an allowable range, and the absolute value of voltage difference between the first and second bus voltage values V, Vis a predetermined voltage value or less.SELECTED DRAWING: Figure 1 |
