<p>PURPOSE:To increase the control characteristic and improve the stability by using the combination of the rotor speed variation signal and the power variation signal. CONSTITUTION:A signal obtained by adding a signal from an uncomplete differential circuit 21 to which a signal DELTAomega proportional to the rotor speed variation of a generator to a signal from an uncomplete differential circuit 22 to which a signal DELTAP proportional to the power variation in comparison with the effective power of the generator is given to an automatic voltage regulator AVR via a limiter circuit LIM for limiting the output of a system stabilizer. In such a way, a stabilizing signal is obtained in the form of the combination of the speed variation signal and the power variation signal, so shortage of each stabilizing signal can be compensated to increase the control characteristic and improve the stability.</p> |
