Intelligent Location Method for Single-phase Grounding Fault in Distribution Network Based on Wavelet Packet
In order to reduce the intelligent positioning error of single-phase grounding faults in distribution networks,a wavelet packet based intelligent positioning method for single-phase grounding faults in distribution networks is proposed.This method establishes a mathematical model for intelligent location of single-phase grounding faults in distribution networks using wavelet packets through the study of the principle of wavelet packets.The hidden layer excitation function in this model is mainly wavelet function,and the method of combining wavelet energy with the active and reactive characteristics of transient zero sequence current realizes information fusion in the power system,completes the positioning of system faults,and adds momentum term during the training process,A new weight initialization method has been adopted to improve the learning efficiency of the network and thereby reduce fault location errors.Simulation experiments were conducted using MATLAB,and the results showed that the proposed method is effective and can achieve more accurate fault localization.
