摘　　要： 对三相感应电动机由单相电源供电和用电容器作为相平衡器的瞬态行为进行仿真分析。为了得到瞬态特性,根据三相感应电动机在A、B、C相坐标系下的动态数学模型和推导出三相定子绕组端电压约束条件,编写计算机仿真程序,通过实例对Y接法的三相感应电动机由单相电源供电和用电容器作为相平衡器时的瞬态过程进行仿真计算,对仿真结果进行分析用对称分量法分析了电动机对称运行时需要满足的条件,并由此初步计算电容的数值,然后通过计算机仿真较准确地加以确定。 This paper deals with the transient behavior of a three - phase induction motor operating with single - phase supply and using capacitor as phase balancer. To get the transient features, MATLAB language is used to develop the computer simulation program by means of the dynamic mathematical model of three - phase induction motors in phase quantities and push derivation three - phase stator winding end voltage restraint condition. The program is applied to emulate transient process of single - phase operation of three - phase induction motor with star - connected through example. Symmetrical components method is employed for analysing the minimum asymmetrical operation condition of three - phase induction motor operating with single - phase supply and using capacitor as phase converter, and by this preliminary calculation the value of capacity is determined comparatively accurately through computer emulation. Emulation results are also studied here.
