通过对动车组牵引传动系统的结构和工作原理的分析，基于Simulink建立了包括牵引Transformer、两个四象限变流器、中间直流电路、PWM逆变器和牵引电机在内的牵引传动系统的离散数学模型，结合dSPACE实时仿真器，建立了牵引传动系统实时仿真平台，该平台包括虚拟牵引传动系统、真实的牵引控制器及其连接盒，能够模拟牵引传动系统物理量的变化，首次将虚拟驾驶员控制台和虚拟中央控制单元加入到真实的-时间平台，模拟牵引传动系统对驾驶员动作的响应，在该平台上对车载TCU程序进行了测试，输出的牵引特性曲线与设计的牵引特性曲线相似，四象限变流器和牵引电机在牵引和制动工况下的电压和电流均满足牵引和制动控制要求，结果表明，该系统具有真实的-时间牵引传动仿真平台能够准确地模拟真实的牵引传动系统，可以利用平台中的虚拟牵引传动系统代替真实的牵引传动系统对牵引控制单元进行研究和测试。
A discrete mathematical model of the traction drive system,including a traction transformer,two four-quadrant converters,an intermediate DC circuit,a PWM inverter and a traction motor,is established based on Simulink through analyzing the structure and the working principle of the traction drive system of an electric multiple unit.Combined with a real-time simulator named dSPACE,a real-time simulation platform of the traction drive system is established.The platform,which includes a virtual traction drive system,a real traction controller and their connect box,can simulate the changes of physical variables of the traction drive system.And it's the first time that a virtual driver's console and a virtual central control unit join the real-time platform to simulate the response of the traction drive system to the drivers' actions.An on-vehicle TCU program is tested on the platform,the output traction characteristic curve is similar to the designed one,and the voltages and the currents of the four-quadrant converters and the traction motors under the traction and the brake conditions meet the traction and the brake control requirements.All the results show that the real-time traction drive simulation platform can accurately simulate the real traction drive system,so the virtual traction drive system in the platform can be used to study and test the traction control unit instead of a real one.
