Abstract
Two generation systems,each including inverter,are switched over between series connection and parallel connection by switching section,. Reference waveform signals are mutually communicated between the two generation systems through communication lines,. When a phase difference between these two reference waveform signals is within a predetermined range, the inverters are driven to generate an output alternating current. One of the conduction angles of thyristors,in two converters,which is larger than the other is inputted to a deviation detector,. Based on a deviation of the conduction angle inputted from a target conduction angle, an updated target rotational speed is set in a calculator,. A throttle controller,controls a throttle opening angle so that an actual rotational speed converges into the target rotational speed. A ground fault is judged based on a potential difference across one node point in a first arm, connected to the earth and the other node point in a second arm of a resistance bridge provided across a pair of output terminals of either one of the inverters.
