摘要

在充分考虑短路绕组间磁路耦合的基础上，建立了异步电机定子绕组匝间短路故障在三相静止坐标系下的数学模型，并通过坐标变换得到其在两相静止坐标系下的简化故障模型，对该模型进行仿真研究，采用扩展Park矢量法分析电机定子电流故障频谱。仿真结果验证了模型的正确性和有效性。

Abstract

On the basis of fully considering magnetic coupling between the short-circuit windings, the mathematical model of aninduction motor with stator winding inter-turn short-circuit fault in the three-phase stationary coordinate system was established firstly, thena simplified fault model in the two-phase stationary coordinate system was obtained by the coordinate transformation, finally the motorstator current spectrum was analyzed and simulated by using extended Park’ vector method. Simulation results verified the correctness andvalidity of the induction motor model with stator inter-turn short-circuit fault.
