异步电机交流传动试验台的研究

大功率交流传动系统的研究、开发和生产,离不开牵引电机、变流器以及控制系统性能的实验研究和测试,这就需要一种有力、有效的交流传动试验系统。在现有试验系统主电路结构对比研究的基础上,本文对其中最适于长期进行大功率试验的结构方式——互馈试验台——进行了深入研究。本文在互馈试验台上实现了异步电机的矢量控制,并在该试验台上进行了大量试验研究。试验结果表明试验台可以完成异步电机交流传动试验台的各种试验,并且具有好的动态、稳态控制性能。

Study on AC Drive Test-bed for Induction Motor

As high power AC drive systems,AC locomotive and EMUs developing,an effective experiment system is quite required to test the converter,traction motor,etc.This paper focuses on the research of AC drive test-bed.First,already existing main circuit constructions of test-bed are analyzed contrasively and the most reasonable one is chosen for deeply study.Then the control system is introduced from the aspect of control strategy.At last experiment study is carried out and experiment results are shown.These resul...
