蓄电池电机车交流传动控制的研究

Research on AC driving control of battery locomotive

文章介绍了一种矿用蓄电池电机车的交流变频调速传动系统,采用无速度传感器的直接转矩控制策略。通过与直流传动电机车的对比实验显示,这种交流传动系统具有牵引力大,起动电流小,调速性能优良,以及节能效果显著等特点。

The paper introduced the AC frequency converted speed controlled driving system of the mine battery locomotive. The driving system has a direct torque control strategy with a non speed sensor. In comparison with DC driving electric locomotive, the test showed that the AC driving system had a lager haulage force, a small current for starting, excellence in speed control, energy conservation and other obvious features.
