Abstract

PURPOSE:To conduct a commercial synchronous parallel-off without a power- factor detector by operating the power-factor angle of a motor from a slip frequency and dividing a primary current into flux and torque components to control them. CONSTITUTION:When a synchronous parallel-off is conducted, a motor voltage phase thetaV is computed by a motor voltage phase arithmetic circuit 43 through the use of a position angle theta0 of a flux having an always constant phase relation to a voltage in place of an inverter output voltage, and said motor voltage phase is compared with a source voltage phase thetaP by a phase comparator 10 to output a phase error theta. Said phase error theta is outputted as a torque current component correction quantity IA through a low-pass filter 11. The outputted torque current component correction quantity IA is switched over to the output signal ITR of a speed control circuit 34 by a torque reference switching circuit 44, and said torque current component correction quantity IA is outputted as a torque current component ITRQ.
