研究三相异步电动机节能问题,三相异步电机具有一种非线性、多参数、具有时变性,传统节能控制技术难以保证系统控制性能达到全局最优,为提高三相异步电动机的节电率,提出一种电能损耗模型和神经网络相结合的三相异步电机节能控制方法,并通过仿真验证上述方法的有效性。仿真结果表明,无论三相异步电机处于轻载或空载状态,均可以获得较高节能控制效率,使电能损耗达到最小。

Research energy saving problems of three-phase asynchronous motor. Three-phase asynchronous motor is the system with nonlinear, multi parameter, time-varying , and it is is difficult for traditional energy-saving con- trol technology to guarantee the performance of the control system to reach the global optimum and the asynchronous motor ＂s energy-saving rate. The paer put forward an electric energy loss model and a neural network combined with three-phase asynchronous motor energy saving control method. The simulation results verify the validity of the meth- od. The simulation results show that, regardless of the three-phase asynchronous motor at light load condition, the method can obtain high efficiency energy saving control, so that the electric energy loss is minimum.
