摘要：Abnormal condition in a power system generally leads to a fall in system frequency, and it leads to system blackout in an extreme condition. This paper presents a technique to develop an auto load shedding and islanding scheme for a power system to prevent blackout and to stabilize the system under any abnormal condition. In this paper, load shedding is done calculating the rate at which the system frequency is varying during an abnormal condition. The rate of change of frequency （rocof） technique proposes the sequence and conditions of the applications of different load shedding schemes and islanding strategies. It is developed based on the international current practices. It is designed, and an auto load-shedding and islanding scheme is developed which is quick and is highly helpful in obtaining system stability when compared to existing load shedding scheme（traditional scheme）. The effectiveness of the developed scheme is investigated ,simulating different abnormal conditions in Matlab and the results are analysed. The proposed model work better when compared to old existing models.
