Phase control switching device
In a phase control switching device that controls a closing phase of a three-phase switching device connected between a power-supply-side transmission line and a compensation transmission line having a shunt reactor, a closing-phase control unit operates based on a closing command to the three-phase switching device, generates, for each phase, a closing phase in which the three-phase switching device is closed at zero points, both polarities of which are inverted into the same polarity, among zero points where zero points of a voltage changing ratio and zero points of the shunt reactor current coincide with each other, and controls the three-phase switching device.
