A thyristor control signal is generated based on a variable load reactive power signal of a variable load connected to a bus bar and a voltage signal of the bus bar, and a high impedance transformer or a transformer and a reactor connected to the bus bar are energized and controlled by the thyristor. Compensates for variable load reactive power,
In the reactive power compensator configured to keep the bus voltage constant, an active filter is connected in cascade to the multiplier of the variable load reactive power detection circuit, and an active filter and a square rooter are connected in cascade to the squarer of the voltage control circuit. 1. A reactive power compensation control device characterized in that a thyristor control signal is created based on an output signal obtained by adding the outputs of both.
