| 摘 要： | 在分析城市地铁车辆电气牵引系统工作原理的基础上,首先对牵引逆变器直流侧电流、直流电网电流及其谐波分量进行了理论推导,然后详细讨论了线路滤波器的滤波作用,最后结合MATLAB仿真软件以牵引逆变器方波运行实例对直流电网电流进行仿真分析,仿真结果验证了理论分析的正确性,也表明推导的直流电网电流的计算公式可以作为电网电流及其谐波计算和损耗估算的依据.

| Abstract: | Firstly this paper made the theoretic inference on the dc side current contents of traction inverter and of dc supply network based on the analysis of electric traction system of urban metro vehicles. Then the function of line filter was analyzed in detail. Finally dc supply network current harmonics were quantitatively analyzed under the typical square wave mode with the MATLAB simulation software. Simulation results show that the theoretic analysis is valid and the derived formula in the paper provides a method to assess the current harmonics and power loss of dc supply network. |
