摘要
本文在汽轮发电机交轴运算电抗三阶模型的基础上，导出了交轴超-起瞬态、超瞬态和瞬态电抗的表达式。通过计算不同转差下发电机交轴运算电抗的频率特性，给出了用最小二乘法拟合的二阶和三阶模型；并以600MW汽轮发电机为例，阐述了交轴各电抗的计算方法。
In this paper, the frequency characteristics of q axis operational impedances are calculated by finite element method, then the second and third order q axis models ofturbogenerator are derived by using the least square method. Taking 600MW turbogeneratoras an example, the method of detendning the q axis transient and subtransient reactances ispresented.
