摘要
对SemihexTM单相感应电动机定子绕组开路故障运行时的动态过程进行仿真分析。为了得到瞬态特性,推导出电动机定子绕组端电压约束条件,建立起单相SemihexTM电动机正常运行和故障运行时在αβ 0坐标系下的瞬态数学模型,编写计算机仿真程序,通过实例对电动机的定子绕组开路故障状态的瞬态过程进行仿真计算,对仿真结果进行分析。结果表明,在这些故障状态下电动机带额定负载都不可以长期运行。
The one phase stator winding open-circiuted transient process analysis of single-phase operation of three-phase induction motors with the Semihex^TM connection was researched. To get the property of transient state, according to boundary equations of three-phase induction motor with the Semihex^TM connection, the stator winding terminal voltage constrains conditions of normal operation and fault operation was educed and the dynamic mathematical model of single-phase Semihex^TM motor in αβ0 coordinate system was constructed, and the computer emulation program was compiled. The program was applied to emulate transient process of single-phase Semihex^TM motor during normal operation and fault operation with one phase stator winding open-circiuted through an example. Emulating results were also studied.
