摘　　要：对三角形接法的三绕组单相异步电动机的相绕组开路以及电容器开路的故障运行动态过程进行了仿真分析。为了得到动态特性,根据三相异步电动机在α-β坐标系下的动态数学模型以及故障状态时的端点边界方程推导出绕组的端电压约束条件,编写计算机仿真程度,通过实例对电动机稳定运行时突然发生的几种故障状态的瞬态过程进行仿真计算,并对仿真结果进行分析。This chronous motors with paper deals with the transient analysis of tri-winding single-phase capacitance asyndelta-connected during fault operation. To get the transient characteristics, according to the mathematics model of three-phase asynchronous motors in α-β coordinate, considering the stator winding terminal voltage constrains condition of fault operation, the practical simulation program was written. The program was applied to emulate transient process for normal operation and fault operation with one phase stator winding open-circuited and capacitor disconnected of tri-winding single-phase asynchronous motors with delta-connected through a example. Emulation results were also analyzed here.
