Based on the linear model of governing object,this paper calculates the turbine transfer coefficients and six Ki parameters of generator in different work point,and the effect of these changing on latent root are calculated.

以调节对象线性化模型为基础，从1个实例计算入手，计算了不同工况下水轮机传递系数和发电机6个参数的变化情况，进而计算这些参数变化对调节对象特征根的影响。
