Variations in load reactive power are brought down to desires value at any load variations at minimal power of thyristor-reactor group irrespective of particular power of condenser bank of compensator. Automatic selection of working point is effected due to dynamic (at high time constant) storage of peak-to-peak variations in load reactive power. This peak-to-peak value with definite factor depending on deviation from standard supply voltage fluctuations sets up working point of thyristor-reactor group at minimal level. Coefficient computing channel is astatic and maintains minimal initial offset of working point for each phase of thyristor-reactor group in all possible operating conditions of load.
