御装置。 In a control device for a reactive power compensator that is connected to a grid and controls the reactor current by controlling the phase of the thyristor to suppress fluctuations in the grid voltage, the positive side and negative side thyristors connected in series and antiparallel to the reactor are It is equipped with a side gate pulse generation circuit and a negative side pulse generation circuit, and a power synchronization circuit and a pulse generated by dividing the power supply frequency from the circuit, and counts a certain number of pulses corresponding to a half cycle at the power supply frequency, and generates a negative side gate. 1. A control device for a reactive power compensator, comprising: a counter that outputs a pulse signal; and a counter control that receives a gate pulse from the positive side gate pulse generation circuit and provides a reset signal to the counter.
