Simulation Study on Starting Process of Three Phase Induction Motors in Stator Circuit Series Asymmetrical Resistance

对三相笼型异步电动机定子串不对称电抗的起动过程进行瞬态分析。为了得到起动特性,根据三相异步电动机在相坐标系下的瞬态数学模型,编写计算机仿真程序,通过实例对三相笼型异步电动机的定子电路一相串联电抗时的起动过程进行仿真计算;用对称分量法分析定子电路一相串联电抗时的不对称系统,确定起动电抗的数值。对仿真结果进行比较分析。

This paper deals with the transient analysis of three-phase cage-type induction motors during series asymmetrical reactance stating in the stator circuit. MATLAB language was used to develop the computer simulation program by means of the dynamic mathematical model of three-phase induction motors in phase quantities. The program was applied to series one reactance starting operation process of three-phase cage-type induction motors in stator one phase circuit.Symmetrical components method was employed in the analysis of the asymmetrical system,the value of the starting reactance was determined.Emulation results were also comparatively studied here.
