摘　　要：基于大量牵引负载谐波实测数据,分析了电气化铁道牵引负载谐波的分布特征,利用电磁暂态分析软件(ATP)建立牵引变电站220 kV地区供电系统元件的谐波计算模型,并对供电网络进行了不对称谐波潮流仿真计算。仿真结果与测量值比较,表明该方法对研究电气化铁道供电系统谐波分布行之有效。Based on the measurement implemented at a traction substation, this paper analyzed the power supply system of electrified railway as well as its harmonic characteristic. The harmonic analysis model for the elements of power system under unbalanced condition was presented with ATP software, based on which the harmonic calculation was carried out for the regional power network. Through out the analysis, the harmonic pollution in the power supply system was evaluated, estimation of the most predominant harmonics in network was also presented. The results of the harmonic simulation were compared with actual measurements, and the proposed method as an effective way for the harmonic study of electrified railway was verified.
