基于EMT P软件仿真绝缘子串的电压分布
Voltage Distribution of Insulator Chain Based on Electro-magnetic Transient Program Software Simulation
摘要
Abstract
Existence of faulty insulator and zero resistance insulator is dangerous to safe operation of power system. For get-ting know of affect on voltage distribution by faulty insulator and zero resistance insulator at different positions of insulator chain at different frequencies under 220 kV voltage class and in order to detect fault insulators in lines,electro-magnetic transient program software was used for simulation on equivalent circuit of the insulator chain under three different situa-tions including normal and good insulators,faulty insulators and zero resistance insulators. Voltage amplitudes at each insu-lator ends in insulator chain were thus received and experimental result was drawn for analyzing voltage distribution result. Simulation result indicated that voltage of faulty insulator was obviously decreasing,voltage of zero resistance insulator was zero and voltage of other normal insulator was distributing as “U”type. Comprehensive analysis on voltage distribution of insulator chain was proved to be of important significance for optimization design on the insulator and detection on its condi-tion.关键词
