Abstract

PURPOSE:To diminish the current interrupting capacity of an initial excitation contactor, by opening the circuit of the initial excitation contactor, when specified current is detected by a self-exciting current detector and current is set in a state that it is not detected by an initial current detector. CONSTITUTION:When the rotational frequency of a generator 1 comes to almost rated rotational frequency, then the circuit of a field breaker 7 and an initial excitation contactor 12 is closed, and from a battery 15, initial exciting current is fed. Besides, when a pulse generator 11 comes to the output power of the generator 1 for enabling controlling motion to be performed, then the circuit of an automatic/manual change-over contact 18 is closed, and the input of the output signal of an automatic voltage regulator 5 to the pulse generator 11 is provided. Then, specified current is detected by a self-exciting current detector 23, and at a time point when current is set in a state that it is not detected by an initial current detector 24, then circuits are opened together at the initial exciting contactor 12 and the automatic/manual change-over contact 18. After this, a voltage setting unit 17 is operated and set voltage is changed.
