摘要

基于CIT400高速综合检测列车牵引传动系统的结构和牵引特性,运用MATLAB/Simulink软件建立预测电流控制下的高速综合检测列车牵引传动系统仿真模型,仿真分析列车在牵引和制动工况下受电弓短时断电及网压波动时的运行特性,并与实测数据进行对比分析.研究表明:仿真结果与实测数据基本一致,建立的仿真模型能正确反映列车的运行特性,能够满足列车实际运行的动静态要求.%Based on the structure of traction drive system and the traction characteristics of CIT400 highspeed comprehensive inspection train, a simulation model was established by MATLAB/Simulink for the traction drive system of high-speed comprehensive inspection train under predictive current control. The operation characteristics of CIT400 high-speed inspection train were simulated and analyzed upon short-time power failure of pantograph and net voltage fluctuation under traction and brake conditions. Simulation results were compared with measured data. Research shows that the simulation result and measured data are basically identical. The established model can correctly reflect the operation characteristics of the train and can meet the dynamic and static requirements for the actual operation of train.
