Abstract
Aimed at improving the poor start performance and eliminating harmonics pollution to the grid due to the waveform distortion of stator voltage and stator current often occurring during the course of asynchronous machine start,this paper describes the developement of the mathematical model of power factor,based on instantaneous power theory,using 3-phase asynchronous machines for object and according to dynamic equations and optimization of the function of power factor,proposes new control method grounded on the optimal results and provides simulation curves of stator voltage,stator current and real power.The simulation indicates that on different stages of start,new method is able to improve real power,which validates the control method based on instantaneous power theory.关键词
