摘　　要：24脉波整流器由于能量只能单向流动,制动时直流侧能量无法回馈,导致能量利用率较低,直流侧电压脉动大。新型城市轨道交通采用PWM整流器,很好的解决了这一问题。分别建立了24脉波整流器和PWM整流器的仿真模型,采用快扫描的方法分别对基于24脉波整流器的传统牵引供电系统和基于PWM整流器的新型牵引供电系统进行了运行仿真,对仿真结果进行了对比。从仿真的结果可以看出基于PWM整流器的新型牵引供电系统直流侧电压稳定,能提高能量利用率。24-pulse rectifier has lower energy efficiency and higher DC side voltage ripple,because the energy can only be one-way flow and can not be feedback in the DC side when braking.The new urban rail transit solved the problem by adopting PWM rectifier.The model of 24-pulse rectifier and the PWM rectifier was established,and the simulations of the traditional traction power supply system based on 24-pulse rectifier and new type of traction power supply system based on PWM rectifier were made by fast scanning method,and the simulation results were compared.The conclusion can be made that the new type of traction power supply system has a more stable DC voltage,and improves the energy efficiency.
