Analysis of Incorrect Operation of 220 kV Line Protection Power Converse and Its Improving Measures

摘要：

　　This paper analysis a mal-operation event of power converse protection. By deeply analyzing the link between time and mal-operation of power converse protection from theoretical analysis and protective logic, it sums up behaviors of 220 kV line protection tripping behavior under power converse situation,concludes that the reason for mal-operation is power converse protective logic can not adapt to the fault fast removal of the operating conditions. This article presents three measures to these problems. The application results prove the effectiveness of these methods.
