The reactive power compensation system used for preventing the power voltage fluctuation includes an inverter which operates in response to a high-frequency PWM signal based on the reactive power determined from the voltage and current at the receiving point to compensate a sharp varying component of reactive power created by the load, and a capacitor which is connected or disconnected with the power system through a semiconductor switch on the basis of comparison of the load reactive power with preset values so as to supply the leading reactive power back to the power system. |
