异步牵引电机全速域直接转矩控制仿真研究
Research and Simulation on Direct Torque Control in Full Speed Range of the Asynchronous Traction Motor
摘要
Abstract
Electric traction operation was divided into different operation regulatory regions according to the characteristic of asynchronous motor. Pulse width modulation (PWM) technique was adopted for inverter when starting and running in low speed range,and square wave control was adopted when the output power of induction motor reached the nominal value. A direct torque control scheme being suitable for traction motor in whole-speed range was discussed,and a feasible transition strategy for algorithm switch was also adopted to avoid the jump of flux and torque. Finally,the traction and braking conditions of induction motor were simulated on the basis of the simulation model built,and simulation results show that the motor drive system can obtain a perfect dynamic and static performance,satisfy with the requirements of train control,and the validity and effectiveness of the adopted control method are verified.关键词
