Abstract After setting expected failure during power system operation risk assessment, failure isolation contains two steps, one is to identify breaker that should be disconnected, which is called shift switch, the other is to disconnect the shift switch. This paper proposed a method of identifying shift switch of expected failure isolation, where substation topology and complex connection mode were considered, thus filling the research gap and laying foundation for power system operation risk assessment. First, from the viewpoint of failure isolating result, failure elements were classified into independent element and element group. Second, element group and its composition were obtained according to its structural feature. Then, the method of identifying shift switch of failure isolation for all kinds of failure elements was established. Finally, the proposed method is proved to be valid by applying to classical failures of practical power system.
