|
摘要
随着交直交电力机车投入运行数量的增多,由其注入牵引供电系统高次谐波电流所引起的过电压成为影响电气化铁路安全运行的重要因素之一.基于电力机车谐波电流频谱与牵引供电系统谐波阻抗特性的匹配关系,分析了影响牵引供电系统高次谐波过电压水平的主要因素,讨论了高次谐波过电压的一般规律,比较了可应用于抑制牵引供电系统高次谐波过电压水平的技术,讨论了高通滤波器的应用效果,给出了牵引供电系统高次谐波过电压抑制技术的工程实施建议,所提建议对实际施工具有现实的指导作用.
The over-voltage caused by the high harmonic current injected into the traction power supply system is one of the important factors affecting the safe operation of electrified railway with more and more AC-DC-AC locomotives are put into operation.Based on the matching relationship between the harmonic current spectrum of electric locomotive and the harmonic impedance characteristics of traction power supply system,this paper analyzes the main factors affecting the high harmonic over-voltage level of traction power supply system.The general law of high harmonic over-voltage is discussed,and the technique to inhibit the high harmonic overvoltage of traction power supply system is compared.By discussing the application effect of high-pass filter,the engineering implementation proposals for high-order harmonic overvoltage restraining technique in traction power supply system are proposed.The proposals are of practical guidance significance to the actual construction.
