变频器供电的异步电机节能控制运行的研究进展

现有工程中广泛应用的异步电机变频控制具有算法简单、动态特性好的优点,但未顾及电机的节能控制运行。实际应用中异步电机经常处于轻载运行状态,效率非常低,这对缓解能源紧张和控制污染非常不利,因此引起了学术界和工程界的广泛关注。根据压频比的变化说明了电机节能运行的原理,介绍和分析了近几十年来异步电机节能控制研究中的常用实现方法及其优、缺点,同时指出工程应用中存在的问题和今后的研究趋势。

Research Evolution of Energy-Saving Control for Asynchronous Motor Supplied by Inverter

The variable control means of induction motor in engineering at present have the advantages of simplified arithmetic and excellent dynamic performance.But they can not consider the energy-saving control.In practical application, the motor often operates at light load and the efficiency was very low,which was a large disadvantageous for tempering energy tension and control pollution.Thus an extensive attention arises in academe and engineering.Theenergy-saving operation of the machine by varying the ratio of...
