摘　　要：建立了异步电机的多变量数学模型。以异步电动机节能运行为目的,分析功率因数与异步电动机参数及转差角频率Δωi间的关系,以此作为功率因数节能控制的依据,从而在变频调速中实施功率因数控制。This article put forward the multivariable mathematical model of induction motor, to achieve the economical run. Using theoretical knowledge and mathematical derivation methods, analysis the relationship between the power factor and the angular frequency deterioration was discussed, so as to establish the energy-saving power factor control system. Thus, a reliable theoretical basis for the energy-saving of power factor control system on the basis of VVVF in practical work was gained.
