償制御装置。 A reactive power compensator that uses both reactive power control and constant voltage control is used to detect when the grid voltage has become overvoltage, and to detect when the grid voltage has become low voltage, and the operation of these devices. Therefore, a reactive power compensation control device is provided with a switch device that performs a circuit opening operation, and is characterized in that it automatically switches to only grid voltage control when the grid voltage becomes overvoltage or low voltage.
