摘要
该文针对运行中的大功率电动机,存在许多空载和轻载运行阶段,而造成电动机效率和功率因数下降的现象,采用电流检测和PLC控制的策略,从而实现了电动机智能节电高效经济运行。
No load and light load constantly occur in the working of a high power induction motor, thus reduce its power factor and efficiency. This article is to put forward a new intelligent system which make use of current detection and PLC controlling to work generator more efficiently and economically.
