摘　　要：为更好地探究城市轨道交通电力客车安全运行的要求,通过分析地铁列车的牵引过程与制动特性,对地铁牵引变电理论进行理论研究与建模,确定负荷建模的参数,以获取相关的数据,并采用SIMULINK软件仿真对独立牵引变电系统以及在牵引变电系统中添加Buck模块在CCM工作模式下的供电波形进行分析。结果表明,在加入Buck变流模块后,CCM模式工作状态下的系统可以有效地抑制电源谐波,说明优化升级后的牵引供电系统能更好地维护城市轨道交通电力客车的安全运行。In order to better explore the requirements for the safe operation of urban rail transit electric buses,this paper makes theoretical research and modeling of subway traction substation theory,determines the parameters of load modeling,in order to obtain relevant data.Simulink software is used to simulate and analyze the power supply waveform of the independent traction transformer system and the CCM working mode with buck circuit in the traction transformer system.The results show that,after adding the Buck converter module,the system in CCM mode can effectively suppress the power harmonic,it shows that the optimized and upgraded traction power supply system can better maintain the safe operation of urban rail transit electric bus.
