Abstract

PURPOSE: To improve the sysem stability by providing imperfect differential circuit for blocking specific input level at the output of another imperfect differential circuit thereby suppressing the output to AVR to shift to the positive or the negative for long time.
CONSTITUTION: Second stage imperfect differentiating circuit 5 called signal reset is provided at the output of limiter circuit 4, while second stage limiter circuit 6 is further provided at the output and its output is applied as the output of system stabilizer onto the AVR. Here imprerfect differenciating circuit 1 and limiter circuit 4 are used respectively as the first stage. Second stage imperfect differentiating circuit 5 doesn't pass the output applied from first stage limiter circuit 4 when it is constant, and by lengthening its time constant long time shifting of the output signal to the positive or negative due to long period power disturbance or power fluctuation associated with the load control of synchronous machine is suppressed thus to improve the system stability.
