The development of frequency relaying algorithm considering a transient stability
과도 안정도를 고려한 주파수 계전 알고리즘 개발
Abstract
A frequency relaying algorithm which is used system separation and load shedding to improve transient stability is proposed. The algorithm can trip the generator and shed load in the abnormal frequency condition. The computer simulations of load flow analysis is used to determine the amount of load to be shed in an under frequency condition. Furthermore dynamic brake energization in the simulation is performed for the control of overfrequency.
