Abstract
PURPOSE:To alleviate the shock applied to a generator at the time of limiting overexcitation by applying an overexcitation limiting signal in a stepwise signal state. CONSTITUTION:A subtractor 16 subtracts a signal with a value equal to the square of the rated field current from a signal which is the square of the field current. An operational amplifier 14 squares the deviation signal between the field current and the allowable field current. If the field current becomes higher than the allowable field current, a relay 11 is operated. Thus, an operational amplifier integrates the outputs of the subtractor 21 and the amplifier 14 in added output. When the output of the amplifier 21 exceeds the set value, a relay 24 is operated, the deviation signal is converted to a stepwise signal, and the stepwise signal thus obtained is then applied to an automatic voltage regulator 4. Thus, the voltage recovery of the system can be contributed up to the limit of the capacity of the generator, and the shock applied to the generator at the excitation limiting time can be alleviated.
