PURPOSE:To obtain a static reactive power generator which improves transiently the response of the DC voltage control and the response of the reactive current control to the fluctuation of a reactive current. CONSTITUTION:A static reactive power generator is provided with a reactive current controller 14 which calculates a circulating angle reference signal, a DC voltage reference deciding circuit 12 which decides a DC voltage reference signal, a DC voltage controller 13 which calculates a phase difference reference signal, and a pulse width modulation control circuit 10 which controls each inverter based on the circulating angle reference signal, the phase difference reference signal, and the phase reference signal obtained by a 1st sensor. Furthermore a phase difference compensating circuit 16 is added to compensate the phase difference reference signal based on the reactive current feedback signals 1. |
