Single-Point Corona Discharge Location Method of Transmission Line Based on MEM and TS-PSO
摘要
Abstract
With the improvement of the voltage level of transmission lines,the electromagnetic environ-ment problems caused by corona discharge are particularly prominent.In order to obtain the position of the corona discharge point on the transmission line,this article uses an array of four ultra-high frequen-cy sensors to locate it using the time difference positioning principle.We studied the accurate calculation of the arrival time of the detection signal based on the minimum energy method(MEM),constructed a nonlinear programming problem that converts the positioning equation system into solving the discharge coordinates,and proposed the use of tabu search particle swarm optimization(TS-PSO)algorithm to solve the problem.This solved the problem of traditional time difference positioning nonlinear equation system solving algorithm not converging.The problem of non uniqueness and requiring initial values.The experimental results show that the positioning results of the algorithm in this paper are accurate,the algo-rithm's solving speed is improved by 45.7％,and the positioning accuracy is improved by 67％com-pared to traditional algorithms.关键词
