Abstract


In recent years, has become a cascading failure caused by power system blackouts in a wide range of important incentive. In the early stages of the development of cascading failure often present as a run on close to limit the edge of the transmission network, for some low probability accident caused by a wide range of power transfer, resulting in adjacent element overload, form the power system chain overload trip. How to effectively predict chain failure may occur after the subsequent failure to prevent the blackout accident has the important research value. This paper based on the basis of the key transmission section, made a key transmission section in branch overload trip risk assessment indicators, this measures power system happen chain overload trip possibility, on power system, early warning and control to prevent large area blackout accident. A large number of simulation shows the proposed the feasibility and effectiveness of the method.
