Abstract

See full text

A first internal phase difference angle calculator for integrating a deviation between a first frequency command value and a frequency obtained by frequency obtaining device to calculate a first internal phase difference angle, a first internal electromotive voltage command value calculator for proportioning and calculating a deviation between a first reactive power command value and a reactive power obtained based on the value measured by first measuring device, and adding a reference voltage to the deviation so as to calculate a first internal electromotive voltage command value, and a first current command value calculator for calculating a command value of an output current from a first power converter based on the first internal phase difference angle, the first internal electromotive voltage command value, and a voltage measured by the voltage measuring device. The apparatus controls the first power converter based on an output from the first current command value calculator.
