摘　　要：动车组数字仿真对研究机车特性、分析其对牵引供电系统的影响具有重要意义。动车组运行状态不仅随网压波动变化,还受线路条件的影响。基于此,以CRH2动车组为例,分析牵引传动系统的牵引、制动特性和不同线路条件下的阻力特性,研究四象限脉冲整流器、逆变器控制原理。在此基础上,建立动车组牵引传动系统仿真模型,对理想情况、网压波动、坡道、弯道、隧道等不同线路条件下的列车运行情况进行仿真分析,结果证明了该模型的有效性。It is of significance for the research on locomotive characteristics of electric motor train units（EMUs） and the analysis on its traction power supply system to perform digital simulation of EMUs.The operating conditions of EMUs not only vary with the voltage fluctuation of traction power supply system,but also are influenced by line condition.Taking CRH2 EMU as example,the traction and braking characteristics of traction drive system as well as resistance characteristics under different line conditions are analyzed,and the control principles of four quadrant pulse rectifier and inverter are researched.On this basis,a simulation model of traction drive system for EMU is built,and simulation analysis on operating conditions of EMUs under ideal situation,voltage fluctuation of power supply system and different line conditions such as ramp,bend and tunnel is performed.Simulation results show that the proposed model is effective.
