Fault Type Diagnosis Method of Transmission Lines Based on Multi-Source Information Fusion of Operation Inspection and Control Platform
摘要
Abstract
Different types of faults on transmission lines seriously threaten the safe and stable operation of the system.At present,most transmission line fault diagnosis methods refer to a single fault information parameter,and often only consider the zero sequence current information in the fault record.Therefore,this paper proposes a fault type diagnosis method of transmission lines based on multi-source information fusion of operation inspection and control platform,constructs the actual waveform database and related information database under various fault causes of transmission line,uses wavelet packet analysis to extract the fault eigenvalues of different transmission line fault types,and uses machine learning algorithm to complete the fault diagnosis of multi-source informa-tion fusion.Based on the fault characteristic value of the historical tripping line in Hunan area,the simulation results show that the correctness and effectiveness of the method in this paper are verified by actual calculation examples.关键词
