摘要
Abstract
A new method is put forward to assess power system security via a cascading model. Compared with the traditional N-k, the method considers all factors that affect the process of cascading, including the trip of overloading line, the automatic security equipment and the hidden failure of line protection. And the paper focuses on the multiple hidden failure of line protection, and adopts Bayesian network to identify the probability of every fault series. And the paper defines two risk indices, the line risk and the node risk. The simulation on IEEE 30 system proves the effectiveness of the method.关键词
