Abstract
A static reactive-power compensating apparatus in which transients having a frequency below a predetermined frequency are not compensated for while all other variations are fully compensated for. A reset filter circuit is connected between the output of a rectifier circuit and a thyristor control circuit, the latter controlling the firing of thyristors which couple a reactive energy storage bank to the power system for compensating for voltage variations in the system. Preferably, the reset filter has a transfer characteristic of sT.sub.1 /(1+sT.sub.1).
