摘要
接触网电流分布的研究对电气化铁路发展具有重要的意义。基于带回流直接供电方式的接触网原理结构,采用了一种电路模型法,通过以京沪高速铁路的直供区段为例,计算牵引网各部分参数,搭建等效电路模型。结合该区段的牵引网仿真和接触网仿真,将仿真数据与实际接触网电流分布数据比较。结果表明,电路模型法计算得到的接触网电流分布数据具有良好的可靠性,能够很好的完成对接触网各支路电流的研究。
Research on current distribution of Overhead Contact System（OCS） has important significance for the development of electrified railway. Based on the direct a circuit model method is adopted, according to the Beijing S power supply mode of the contact network, hanghai high-speed railway for straight section as an example, the calculation of the parameters of traction network, build the equivalent circuit model. Combined with the traction network simulation and overhead contact system simulation, the simulation data are compared with the actual distribution data of the actual contact network. The results show that the current distribution data calculated by the circuit model has good reliability, and the research on overhead contact system of each branch can be completed well.
