PURPOSE:To rapidly control delivery and reception of power between systems in response to setting of a target power signal by individually rapidly controlling an AC exciting current flowing to an AC exciting winding with two rotary machines as wound-rotor type induction machines. CONSTITUTION:A wound-rotor type induction machines 1A, 1B are coupled directly by a direct-coupling shaft 2. Frequency converters 4A, 4B control amplitudes, phases, frequencies of AC exciting currents flowing to AC exciting windings 3A, 3B. If an error occurs from a target value at terminal voltage or power of the machines 1A, 1B, power control signals 10A, 10B and voltage control signals 14A, 14B are respectively input to the converters 4A, 4B, which are controlled in amplitudes of AC exciting currents flowing to the windings 3A, 3B and phases to a terminal voltage based on voltage detection signals 11A, 11B. Thus, the amplitude and phase of an inner induced voltage formed of a magnetic flux of a secondary circuit of a rotor can be controlled at a high speed. |
