摘要
本文针对架线式电机车供电系统,提出一种由交流异步电动机拖动的调速系统方案,其逆变器采用电压空间矢量控制方式,利用单片机生成PWM波,可优化系统的调速性能。
In view of the power supply system for trolley locomotive, the paper puts forward a scheme of speed control system for electric locomotive driven by AC asynchronous motor. The frequency inverter adopts the voltage-space vector control mode and utilizes the single chip microcomputer to produce the PWM wave, so that the performance of the speed - control system can be optimized.
