摘　　要：基于高电压、大电流IGBT功率器件的牵引逆变器及异步牵引电机已成为高速动车组牵引传动系统的主流电路结构,矢量控制技术作为一种高性能的异步牵引电机控制策略得到广泛应用。现从实用性角度出发,介绍了动车组牵引电机矢量控制系统的几项关键技术,包括电压电流测量、电压解耦算法、转子磁链观测模型、定子频率校正、多模式PWM调制。Traction inverter with high-voltage ＆ large-current power devices and asynchronous traction motor has become the mainstream circuit structure of high-speed EMU traction system, and the vector control technology has been widely used as one of the high performance traction motor control strategies. From the practical point of view, this paper introduces several key technologies of EMU traction motor vector control system, including voltage and current measurement, voltage decoupling algorithm, rotor flux observer model, stator frequency correction and multi-mode PWM modulation.
