| Abstract: | A new fault location algorithm for transmission lines is introduced,the fault location equation is derived from the relationship between the voltages and currents of positive sequence and negative sequence networks when fault happened.This method does not require line parameters,only by means of the GPS synchronization to acquire the voltages and currents data at both ends of the transmission line,and does some related processing about these data,then the location equation can be realized easily.Compared wi... |
