摘要
对Y(星形)接法三绕组单相电容异步电动机故障运行的瞬态过程进行仿真分析。根据三绕组单相电容异步电动机在α-β坐标系下的瞬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,编写计算机仿真程序;通过实例对异步电动机的几种故障状态的瞬态过程进行仿真计算,对仿真结果进行分析。
This paper deals with the transient analysis of tri-winding single-phase capacitance motors with wyeconnected during fault operation. To get the transient characteristics, according to the mathematical model of threephase induction 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-circiuted and capacitor disconnected and capacitor brash short- circiuted of tri- winding single-phase motors with wye-connected through a example. Emulation results were also analyzed here.
