水轮发电机瞬态和超瞬态电抗的数值计算

Numerical Calculation of Transient and Subtransient Saturated Reactances of Large Waterwheel Generator

本文用有限无法求解了大型水轮发电机内的二维正弦涡流场，提出了励磁绕组和阻尼绕组端部漏抗的归算方法，并以清江电站３０１千瓦水轮发电机为例，计算了瞬态和超瞬态电抗的饱和值。

In this paper,the 2D nonlinear sinusoidal addy current fields in a lare waterwheelgenerator are solved by FE method.The cffect o f end leakage of the field winding anddamper winding are considered by referred process,the transient and subtransient saturatedreactances of a 300MW wateewheel generator are ealculated and compared with design da-ta.
