基于PSCAD/EMTDC的高铁在线运行工况电能质量分析

摘要

Following express train electric railways connected into the power grid in large scale, in order to study the power quality change characteristics at system side after express train connected into grid, this paper built up the simulation model of CRH2 type express train tracking power supply system in PSCAD/EMTDC software. Verification was carried out from different angles for the built simulation model of express train. On the basis of matching analysis of express train actual operation working condition, taking Beijing-Shanghai express train Nanjing section for example, this paper analyzed the power quality change characteristics of express train actual operation at system side under different operation working conditions, which provides reasonable suggestions for express train power quality monitoring analysis and treatment and actual operation control optimization.%随着高速电气化铁路的大规模入网，为研究高铁接入后系统侧的电能质量变化特性，在PSCAD/EMTDC软件中搭建CRH2型高铁牵引供电系统仿真模型，从不同角度对所建高铁仿真模型进行了论证，并在对高铁实际运行工况进行匹配分析的基础上，以京-沪高铁南京段为例，分析了高铁实际运行中不同运行工况下系统侧的电能质量变化特性，为高铁电能质量监测分析和治理及实际运行控制优化提供了合理建议。
