Abstract

In order to solve the problems of ground fault line selection in distribution network, the article presents a fault line selection method based on the similarity of the wavelet packet energy spectrum. After extracting a certain data of transient fault zero-sequence current by the wavelet packet decomposition, we can get the energy spectrum distribution and energy spectrum matrix of all lines. Comparing the similarity of the energy spectrum distribution of all lines, a minimum similar principle as the criterion of the fault line is selected. Simulation results verified that this method can accurately and fast select the fault line with good adaptability.
