Then, the rotor of the second variable speed generator-motor is excited and controlled, and the second variable speed generator-motor is connected in parallel with a second power system so that the phase, frequency, and magnitude of the stator-side voltage are made to match with the system in parallel. Then, the rotor of the first generator- motor is demagnetized, and the stator current is reduced to near zero. Thereafter, normal exciting current is applied, and the phase, frequency, and magnitude of control stator-side voltage are made to match with a first power system. Then, the first generator-motor is connected, in parallel with the first system.
