摘要
Abstract
Cascading overload trip often occurs on the fault line's parallel transmission section. This paper gives the risk assessment indicator of line overload trip in parallel transmission section and takes corresponding lines as a set-High Risk Lines Set. By comparing the indicators, we can discriminate the occurrence of cascading overload trip and narrow the range of power system security analysis objects. The assessment indicator takes the interaction and accumulation between failures before and after into consideration. It also overcomes defects of the traditional N-1 system security criteria and N-m system security criteria. At last, the validity of proposed method is verified by the calculation result of CEPRI36 test system.关键词
