摘　　要：以Y/Δ -1 1接线的牵引变压器为例 ,分析了电力牵引负荷产生负序电流和高次谐波的规律 ,并给出了实测数据 ,最后提出了对应的治理措施 ,其中包括合理分配两供电臂的无功补偿容量 ,利用斯坦美兹 (Steinmetz)原理对无功和负序进行综合补偿 ,在牵引变电所的低压侧安装滤波器或静止无功补偿装置 .In this paper, the negative sequence current and harmonics current generated by the electric traction load are analysed through the example of Y/Δ-11 transformer. The measured data is listed. Some ideals of improvement are put forward, which include the rationally dispatching capacitors of the two power supply sections, the comprehensive compensation of reactive power and negative sequence current by means of the Steinmetz principle, the filters or the static var compensators installed in the low voltage sides of traction substation.
