基于DSP矿用蓄电池电机车交流牵引控制系统的研究

摘要

This paper is designed based on the Microchip 16 -bit singlechip microcomputer dsPIC30F6010A mine locomotive traction control system, providing the traction control system hardware and software implementation scheme and circuit structure. The Traction control system realized speed loop control of the mine electric locomotive to adoption of slip frequency control strate- gy and the SVPWM method. The experiment indicates that the traction control system meet operation requirements of the mine electrical locomotives AC variable speed, it can be promoted application in the coal mine industry.%本文研究设计了基于16位高速单片微机dsPIC30F6010A的矿用电机车交流变频调速牵引控制系统，给出了牵引控制系统的硬件和软件实现方案及电路结构。采用转差频率控制策略和电压空间矢量脉宽调制（SVPWM㈨）的控制算法，实现了矿用电机车速度闭环控制。实验结果表明，该牵引控制系统能够满足矿用电机车交流变频调速运行的要求，可以在煤矿行业内推广。
