摘要
针对近年来异步电机节能技术的发展状况,以负载周期性变化而转速基本不变类负载的调压技术为研究对象,指出了节能技术中存在的几个关键问题:控制变量的选择、控制算法和调压过程中出现的电流振荡现象。并对关键问题的研究状况进行了分析和说明,最后对异步电机节能技术的未来发展做出展望。
According to the development of energy - saving technology for asynchronous motor in recent years, the voltage - regulation is studied for induction motor （IM） with periodically varying loads and almost constant speed. Some key problems still exist in the energy - saving technology, including the choice of the controlled variable, the control algorithm and the current oscillation in the process of the voltage - regulation. The evolution of each key problem is analyzed and introduced. Finally, further research developments are discussed in detail.
