摘　　要：硬件在回路仿真可以有效地对电力牵引驱动控制器进行各种条件特别是极限、故障条件下的测试。本文采用dSPACE实时仿真器对大功率电力牵引驱动控制系统进行硬件在回路仿真,建立了电力牵引驱动系统的实时模型,采用双线性插值方法解决了由于固定仿真步长内发生的离散开关事件引起的误差。实时仿真与系统实验对比结果验证了实时仿真系统的有效性和可信度,在开发和测试阶段可以代替实际逆变器和电机进行实时闭环测试。Hardware in the loop（HIL） simulation can test the electrical traction control unit in various condition,especially in fault and the maximum conditions.The HIL simulation of high-power electrical traction system is proceeding in the dSPACE real-time simulator.The real-time simulation model of electrical traction system is established and the error produced by multiple switching events within one simulation time-step is eliminated using the double linear interpolation algorithm.The validity and reliability of the real-time simulation system is verified by the comparative analysis between the HIL simulation and real experiment,so it can replace the real inverter and motor of the electrical traction system in the initial develop and test stages.
