Impact Analysis of Ubiquitous Access of High Peretration Distributed Power Supply on Power Quality of Distribution Network
摘要
Abstract
Aiming at the problems of low accuracy and poor real-time performance of traditional power quality analysis and fault detection methods for distribution network,a fault node detection method for distribution network based on measurement infor-mation of feeder terminal unit(FTU),empirical mode decomposition(EMD)and improved whale optimization algorithm(WOA)is proposed.The proposed method uses FTU information to construct current coding,switching function and fitness function,which can effectively deal with the problem of changeable power flow direction after distributed power supply is con-nected,and realize the initial identification of node status.At the same time,the EMD decomposition of current signal is com-bined to enhance the ability of fault feature extraction and further improve the positioning accuracy.The improved WOA is used to optimize the search process,which significantly improves the efficiency of model operation.The experimental results show that the single-node fault position accuracy of the proposed method is up to 5％higher than that of the original algorithm,the running time is significantly shortened,and the number of iterations required for convergence is the least,which shows that the proposed method has good comprehensive performance and strong robustness.关键词
