基于实测数据的重载电气化铁路电能质量分析

Analysis of Power Quality of Heavy Haul Electrified Railway Based on Actual Measurement Data

简要介绍了电气化铁路的现状和负序、谐波产生的影响及检测方法,针对重载电气化铁路的牵引变电所的测试数据进行分析研究。Matlab是一种应用于计算和仿真的软件,其强大的计算功能、简单易行的编程语言和强大的仿真功能给研究工作者们带来了极大的方便。利用Matlab M语言编程分析测试数据,分析了电压畸变率、不平衡度及谐波电压含有率。最后提出相应的对策和建议。

This article introduces the status quo of electrified railway,the influences caused by negative sequence & harmonic wave and detection methods,analyzes and studies traction substation testing data of the heavy haul electrified railway.Matlab is a software used for calculation and imitation, whose huge calculation function,simple and easy programming language with strongly imitated function bring tremendous convenience to research workers.Matlab M language is used to analyze testing data,unbalanced degree and the containing rate of harmonic voltage.Finally homologous countermeasures and suggestion are put forward in this paper.
