Abstract
A reactive power compensation apparatus for compensating for voltage fluctuation of an AC power supply system includes a first arithmetic circuit for synthesizing a positive-phase fundamental wave voltage signal from voltages of the AC power supply system, a second arithmetic circuit for synthesizing negative-phase voltage signals from the voltages of the AC power supply system, a third arithmetic circuit, coupled to the first and second arithmetic circuits, for synthesizing current instructions from the positive-phase fundamental wave voltage and the negative-phase voltage signals, and a circuit, coupled to the third arithmetic circuit, for generating a reactive power corresponding to the current instructions.
