摘　　要：电气化铁路负荷易对电网母线造成较严重的电能质量污染,有必要通过建模分析。作为两篇系列文章的第一篇,详细阐述了用于分析普铁和高铁在各种工况运行对变电站电能质量影响的建模方法。建模分为变电站建模、牵引网及车辆建模、运行电铁外的其他负荷建模。为保证分析结果的精确性,牵引网模型在已有研究基础上采用链式电路模型,考虑各导线之间的耦合;为比较客车和货车对电网电能质量影响,列车建模计及高铁客车和普铁货车。Considering that electrified railway load easily brings about serious power quality pollution for the power grid buses,it is necessary to give analyses through modeling.As the first part of this two-part paper,the medeling method that to analyze the influence of various operation situations of both ordinary railway and high-speed railway on the substation’s power quality was detailedly elaborated.The modeling was composed of the modeling of substation,the modeling of traction network and running vehicle,and the modeling of other loads except for the studied railway.To enable the accuracy of analyses,the chain circuit was adopted in the traction network model,where the couplings of each conductor were considered.Besides,to realize the comparison of the power quality influence betteen passenger vehicle and truck on the power grid,the modeling of vehicle took into account the passenger vehicle of high-speed railway and the truck of ordinary railway into account.
