摘要:
针对感应电机在低负载率和宽转速区间内效率和功率因数指标发生矛盾的问题,以鼠笼式感应电机作为研究对象,采用动态解耦法构建了电机效率和功率因数指标函数,运用凸集理论证明指标函数在转子频率和转差频率平面内存在最优点,提出将恒频作为约束条件,通过优化指标函数来获得最佳工作点信息的思想。定子电阻温升的参数摄动会影响寻优结果,提出利用人工神经网络减小参数摄动影响,并获得参考指标函数从而调整转速调节器的参数的方法。仿真结果说明上述方法能够实现有参数摄动情况的优化,使电机的指标函数逼近最佳运行点的指标。实验结果表明,优化方法能为控制系统设计提供支持,通过改变功率因数实现节能目的。
Abstract:
Oriented to the conflicts of efficiency and power factor under the conditions of induction machine′s low load ratio and wide speed range,the performance function of the two indices are established and the existence of the optimal point is proved in the plain of rotor frequency and slip frequency by convex set theories.The idea is proposed of optimizing performance functions by taking constant frequency as constraints to obtain the optimal point′s information.Parameters’ perturbations of stator resistance′s exothermic characteristics influence optimizing results.The method is provided to reduce perturbations’ impacts by means of artificial neural network(ANN) and obtaining the reference indices to adopt speed regulator′s parameters.Simulation results indicate these methods can realize the optimizations with parameters’ perturbations and make IM’s performance indices approaching the one of the optimal points.Experiments show optimization methods provide basis for controlling system design and validating energy saving′s effects by regulating power factor′s values.
