In order to study the negativesequence influence to regional power grid caused by autotransformer traction power supply system, formulas of NSeq current and threephase voltage imbalance were derived, based on current distribution analysis of AT traction power supply system and singlephase VVconfiguration train substation. Employing the "train diagram" method, the realtime voltageimbalance curve was obtained in a simulation study, as well as the factors that influence NSeq and some measures to restrain it.

为研究自耦变压器牵引供电系统对地区电网造成的负序影响，首先讨论了AT牵引供电系统、单相VV接线牵引变电站的电流分布，推导得出了负序电流、三相电压不平衡度的计算公式；然后结合"列车运行图法"开发了相应的仿真程序；最后通过一个实际算例，得到了实时电压不平衡度曲线，指出了负序大小的影响因素及相应措施。
