<p>PURPOSE:To cause an electric power line system stabilization circuit to effectively act, by providing an output control circuit which controls the output of the stabilization circuit to judge whether the circuit is needed or not. CONSTITUTION:A power converter 6, which receives the voltage and current of an electric generator 1 to produce a power signal, and a power line system stabilization circuit 7, which performs phase and gain compensation corresponding to the fluctuation in the power line system by the power signal, are provided to control the field voltage of the electric generator 1. An output control circuit 14, which receives the voltage and current of the generator, is provided to open or close a contact switch 10 to control the output of the power line system stabilization circuit 7. It can be judged from an impedance change looking from a relay whether or not the stabilization circuit 7 needs to be operated. As a result, the circuit 7 can be appropriately operated through a simplified mechanism to attenuate the fluctuation in the power line system.</p> |
