Abstract

PURPOSE: To prevent effect to dynamic stability generated by feeding back quantity to be limited to an automatic voltage regulator by changing the output of limiter at speed that directly does not correspond to the alteration of the quantity to be limited.
CONSTITUTION: In an underexcitation limiter 6, an adder 6g adds reactive currents Iq, active currents Ip and therminal voltage et, and emits signals Is. Comparators 6j, 6k each puts out fixed value e1, -e2 when the signals Is are lower than a set value L1 and when the signals are higher than a set value L2 under rhe situation when the set values are L1<L2. Intergrator 61 increases output toward the direction which augments exitation when input is e1, and when input is -e2, decreases its input, but its signals of inverse direction are of monoway nature which do not make output. Output a of the intergrator 61 is supplied to the AVR as a limitting signal.
