Research on Topology Identification Algorithm Based on Levenshtein Distance and Time Slice
摘要
Abstract
Low voltage distribution network topology is lack of maintenance,it is difficult to support the realization of various advanced applications.Therefore,a topology identification algorithm based on Levenshtein distance and time slice is proposed.Firstly,the topology structure of distribution network is analyzed,and the current characteristics are used to identify the topology.Secondly,the extraction method of current event is described.CUSUM event detection algorithm with improved sliding window is used to extract current event.Then,the Levenshtein distance algorithm and time slice method are described to compare the current sequence of the box substation and the current sequence of the user meter box acquisition equipment,and the sequence matching degree is proposed to describe the user-transformer topology correlation degree in distribution transformer area.Finally,the feasibility and accuracy of the method are verified by calculation and analysis based on the field data.关键词
