ABSTRACT:
This invention relates to a power system stabilizing apparatus for a synchronous generator, which comprises two power system stabilizers for raising the stability of an electric power system. The characteristics of one stabilizer is preset so as to increase the braking power in the same way as in a conventional power system stabilizing apparatus, while the other one being preset so as to increase the synchronizing power, so that phase compensation elements of both power system stabilizers can be varied in accordance with the drift amount of the generator such as the revolution deviation of the rotor thereof, the output deviation thereof, the frequency deviation of the terminal voltage thereof, etc. thereby realizing high static and transient stability.
