摘要
异步电动机在轻载运行时效率会明显下降,由于异步电动机应用广泛,优化其运行效率对节能减排具有重要意义。该文总结了近来年异步电动机效率优化控制的研究成果,其中包括基于电机损耗模型的损耗模型控制法、基于输入功率检测的搜索控制法和混合控制方法,介绍了几种典型算法的原理和性能,并指出了异步电动机效率优化的研究方向。
When an induction motor work at the state far from the rated conditions,its efficiency will reduce greatly.As induction motor is used extensively,efficiency optimization of induction motor drives has great significance for saving energy.This paper overviewed the research progenies of efficiency optimization on induction motor recently,including the loss model controller,search controller and hybrid control strategies.Some typical algorithms were analyzed,and the further research direction was pointed out.
