When the transmission lines fault occurred due to lightning strike, and the lightning strike point is not the same as flashover point, double ended traveling wave fault location device will locate out lightning strike point rather than flashover point. So traveling wave location accuracy will be adversely affected. Based on the fault information of the first head that double ended felt in subsequent wave heads which polarity is the same as first wave head, this paper identifies the consistency of lightning strike point and flashover point, and proposes the method of “distance consistency comparison” to locate flashover point when lightning strike point and flashover point are inconsistent. Meanwhile, the applicability and influencing factors of the location method are analyzed. Simulation experiment and real data verify the reliability and validity of proposed new method.
