Abstract
PURPOSE: To enable a stabilized supply of power to the prescribed load and a reduction or elimination of labor for the operation, by making an automatic valve changeover from control valve to bypass valve of the main stop valve while operating a frequency control at the time of single operation, and operating a control of prescribed frequency still after the valve changeover.
CONSTITUTION: A difference of generator frequency is detected in such manner with an output voltage v1 of a potential transformer PT, that takes out the terminal voltage of a generator 11, inputted to a frequency detector 2 and a voltage signal v2, proportional to the frequency difference, outputted to a voltage detector 1. The voltage detector 1 works when a frequency of the generator is below the reference frequency, and closes a detecting contact 1a, and a switch X closes to actuate a relay A. And with the voltage detector 1 working, a relay D works, and after the lapse of time more than a limited time till returned to a reference frequency fa under a control of frequency, a time limit operating relay DT works, with a contact DT made open, and a generator frequency difference V2 controls CV9 through a contact B-2.
