    • PURPOSE:To effectively automatically control a synchronization when a generator is connected in parallel with other operating generator by forcibly reducing a frequency before the generator is paused and storing an initial frequency at the time of reuse. CONSTITUTION:If a system controller 11 controls to stop a thyristor inverter type shaft generator (S/G) 12 when a stop signal S3 is input, it outputs an initial set request signal to a frequency control unit 13. When an initial frequency set signal is input to the controller 11, a frequency drop signal S6 corresponding to the set signal is output, and the signal S6 is transmitted through an adder 10 to a DC motor 14. An analog signal generator 15 is driven by the motor 14, a signal value is stored. The signal stored in the generator 15 is input to the unit 13, and the output frequency of the S/G 12 is controlled in response to the signal.
