摘　　要：为了分析牵引供电系统产生的谐波和负序电流所造成的影响,建立了基于PSCAD/EMTDC的典型牵引供电系统和公用电网的模型。在V/V接线形式的牵引变压器下,分析两供电臂机车不同台数运行方式下产生的谐波和负序的影响。In order to analyze the influence caused by harmonic and negative sequence generated by traction power supply system,the models of typical traction power supply system and public power grid based on PSCAD/EMTDC are established.The impacts of harmonic and negative sequence of two feeding section locomotives under different operating modes are analyzed in detail based on the V/V traction transformer.

关 键 词：牵引供电系统 V/V接线 谐波 负序
