摘要为准确分析水轮发电机励磁绕组匝间短路时定子齿壁电磁力的分布特点和变化规律，利用ANSYS软件建立了某水轮发电机有限元模型，并结合麦克斯韦应力法，对发电机励磁绕组不同程度短路故障时定子齿壁动态电磁力进行计算，得到了定子齿壁动态电磁力分布情况。结果表明：水轮发电机励磁绕组匝间短路故障后，定子铁心受到不平衡电磁力，且不平衡电磁力呈现槽口大、槽底小的变化规律，随着短路匝数的增加，定子铁心动态电磁力大幅增大。

Abstract: To accurately analyze the distribution characteristics and variation rules of the stator slot wall electromagnetic force during inter-turn short circuit of hydro-generator excitation winding, a finite element model of a hydro-generator is established by ANSYS software, and the dynamic electromagnetic force of stator slot wall is calculated with Maxwell stress method. The dynamic electromagnetic force distribution on the stator slot wall was obtained. The results indicate that the stator core experiences unbalanced electromagnetic forces because of the inter-turn short circuit of the hydro-generator excitation winding, and these unbalanced electromagnetic force shows the change law of large groove and small groove bottom. Furthermore, the dynamic electromagnetic forces on the stator core significantly increase with an increase in the inter-turn short circuit of the hydro-generator excitation winding.

Key words: hydro-generator excitation winding inter-turn short circuit dynamic electromagnetic forces maxwell stress method
