摘要
本文在文献的基础上,用有限元法对异步运行时125MW汽轮发电机的非线性二维涡流场进行了计算,得到了励磁绕组短路、计及非线性时电机内的磁场分布及其运算电抗.
On the basis of reference[1], the 2D non-linear sinusoidal electromagnetic fields of a 125MW turbogenerator under asynchronous operation are studied in this paper. The saturated magnetic field distribution and operational impedances with field winding short circuited are obtained.
