摘要 :  电力牵引传动系统是高速动车组和大功率电力机车的原动力，其发展方向是功率大、重量轻、体积小、可靠性高和低成本，所以电力牵引传动系统采用先进的交流传动系统。电力牵引传动系统主要分为3个主要环节：网侧单相PWM整流器实现功率调节，电动机侧三电平逆变器实现频率变换，异步牵引电动机和机械传动部分实现机电能量转换。27750
本论文主要研究牵引变流器工作原理、异步电动机的矢量控制技术、动车组牵引和制动控制策略等。通过搭建牵引传动系统各部分的Matlab仿真模型，模拟高速动车组在各种控制条件(牵引、制动)下的运行情况，观测各种性能指标，包括动车组速度，网侧的电压、电流、功率因数，牵引电动机转矩、转速、电流等，这对于动车组的设计和运行有一定的指导意义。

Simulation of traction motor car trunk control system
ABSTRACT:Traction power system of high speed EMU is the motive power and high power electric locomotive, the direction of its development is the power, light weight, small volume, high reliability and low cost, so the electric traction drive system using the advanced AC drive system. Electric traction drive system is pided into 3 main steps: network side of single phase PWM rectifier for power control, the motor side three level inverter to realize the frequency transformation, the realization of electromechanical energy conversion and a mechanical transmission part of asynchronous traction motor.
This paper mainly disicussed the work principle, traction converter induction motor vector control technology, traction and braking control strategy. Through the platform of the Matlab simulation model of the traction drive system, the simulation of high speed EMU under various control conditions (traction, braking) conditions, observation of various performance indicators, including EMU speed, voltage, current, power factor of network side, traction motor torque, speed, current and etc., which have a certain guidance significance for the design and operation of emu.
Keywords: electric traction drive system; induction motor; vector control; MATLAB simulation
