Investigation of Power System Cascading Failure and the Causes

摘要

Power system is a highly integrated network and due to this the disturbance in one area will spread to another area. Improper operation and late response of control and protective device lead to cascaded events which if not attended properly and timely than blackout condition may arise. The witnessing reports on the past decades blackouts reveal this unavoidable truth. Among the several natural causes, protection system failure is one of them. In the past fifty years, several major blackouts were mandatory and transparently reported to the public. These reports helped researchers in their research paper to study and suggest various solutions for aforementioned problem. This paper tries to make cohesion with the series of events of power outage in human history and try to identify and categorize various causes of power system blackout.
