摘要
针对矿用直流架线电机车在调速过程中采用落后的直流电机方式及浪费大量电能的问题,提出了一种由交流异步电动机拖动电机车的调速系统方案。逆变器采用电压空间矢量控制方式,利用单片机生成PWM波,优化了系统的调速性能。
This paper is aimed at a solution to the electric energy waste resulting from the speed adjustment direct current traction locomotive in the case of use of the backward speed adjusting way-direct motor.The paper puts forward a new method of the electric locomotive which is droved by AC asynchronous motor, speed-control system. The frequency inverter uses the Voltage-space Vector Control and uses the single chip produce the PMN wave, so that the performance of the speed-control system can be improved.
