Abstract:   (275 Views)

Occurrence of large power deficits are the main cause of black outs in power systems. Usually, large power deficits occure as a result of large generating units or tie-lines outage. Considering the impact of electricity on economic growth of countries and daily life of people, triggering a blackout might be a goal of sabotage or military attacks. Underfrequency load shedding is commonly used to prevent blackout in case of large power defcits. In fact by curtailing part of the loads, load shedding schemes retain the power balance and keep the system stability. In this paper, an underfrequency load shedding method based on wide area monitoring system is proposed. In this load shedding scheme, the amount of load to be shed, in case of large power deficits, to preserve the stability of power system is determined based on the estimated minimum frequency. The effectiveness of the proposed method in different conditions, considering power system parameters variation, is proved using simulation studies.
