ABSTRACT:
A motor control unit executes a system voltage stabilization control for suppressing variation in a system voltage by operating reactive power of a motor/generator unit including an AC motor, and executes a conversion power control to control the output power of a voltage boosting converter to a command value. A target power operation amount necessary for stabilizing the system voltage is distributed to a motor/generator power operation amount command value and to a conversion power operation amount correction value. The target power operation amount can be obtained by being shared by the motor/generator unit and the voltage boosting converter, even when the target power operation amount is in excess of a limit value of power control amount of the motor/generator unit.
