The accuracy and reliability of the main components of travelling wave natural frequency is the key of travelling wave in the fault location method based on the natural frequency. To avoid the problem that traditional algorithms rely on a single primary natural frequency are not reliable, a new method considering the global primary natural frequency which is stroked by the fundamental and harmonics is proposed. The calculated fault distance is more accurate and reliable. And the key in the extraction of the natural frequency of the main ingredient adopt the ensemble empirical mode WVD algorithm to improve frequency resolution while effectively suppressing white noise, thus further improving the location accuracy. Simulation experiment by EMTDC show that the method proposed in this paper can get better stability, higher reliability, reduce ambient noise, and the position is not affected by fault distance or other factors.
