ABSTRACT:
A reactive power controller for controlling a reactive power output from a self-commutated inverter capable of eliminating an uncontrolled reactive power at the starting moment of its operation. The reactive power controller includes a device for producing a signal indicating amounts to be adjusted of an amplitude and a phase of an output AC voltage of the self-commutated inverter, in accordance with a DC voltage over a DC capacitor and an AC voltage of an AC system power source, and a device for adjusting the amplitude and the phase of the output AC voltage of the self-commutated inverter in accordance with the indication of the producing device.
