| 摘 要： | 为了研究转子偏心对不同绕组形式的大型凸极同步发电机的空载支路感应电动势的影响,本文采用"分片模型"和非线性二维时步有限元法对转子偏心及定子斜槽发电机在叠绕组和波绕组时的支路感应电动势进行了计算.与一台3kW、12极的凸极同步发电机空载支路感应电动势实验结果的比较说明了计算方法的准确性,同时相比于波绕组发电机,转子偏心对叠绕组发电机支路平衡性影响更大.

| Abstract: | Multi-slice model and 2-D nonlinear stepping finite element method are proposed for calculation the no-load branch induced voltage of a salient-pole synchronous generator with eccentric rotor and skewed stator slots under different stator winding connection. The exactness of this method is verified by the comparison of the calculation results and experiment results on an eccentric 3 kW 12-pole synchronous generator. Meanwhile, the comparison shows the effects of eccentricity on the equilibrium of the branch... |
