摘　　要：随着地铁、轻轨、有轨电车等轨道交通的大力发展,城市轨道交通牵引供电系统是否正常运行直接关系到城轨交通的安全稳定运营,进行城市轨道交通直流供电系统的仿真建模对轨道交通牵引供电系统设计、施工和运营阶段判断可能的故障类型和制定可行的处理方案具有重要作用,本文首先介绍了城市轨道直流供电系统的结构组成,然后采用MATLAB/Simulink对城轨直流供电系统进行仿真建模,分别介绍了35KV中压电源、整流机组和牵引网的仿真建模方法和仿真参数的计算方法。With the vigorous development of metro, light rail, tram and other rail transit, whether the normal operation of urban rail transit traction power supply system is directly related to the safe and stable operation of urban rail transit, simulation modeling of urban rail transit DC power supply system for rail transit traction power supply system design, construction and operation stage judgment possible fault types and development of feasible treatment scheme plays an important role. This paper first introduces the structural composition of urban rail DC power supply system, and then adopts MATLAB/Simulink simulates and models the urban rail DC power supply system, and introduces the simulation modeling methods and calculation methods of 35KV medium voltage power supply, rectifier unit and traction network.
