摘　　要：基于水轮机流量调节方程及单位参数的定义,导出了具有线性特性的水轮机特征方程。在此基础上,采用线性数据拟合方法,并利用模型水轮机综合特性曲线,求出了水轮机转轮出口处的平均过流断面面积和平均半径等几何参数,能用于使用内特性法研究水轮机的过渡过程及近似求出模型水轮机出口处的平均流速和扩展水轮机的高效率区域特性曲线。According to the hydraulic turbine flow equation and the definition of unit parameters,turbine characteristic equation with linear characteristics is deduced.Based on the composite characteristic curve of model turbine,linear data fitting method is applied to calculate average flow cross-section area and average radius of runner outlet,which can be used in the research of the transition process of turbine with internal characteristic method and be used to obtain the average flow velocity of modal turbine outlet and expand the regional characteristics of high-efficiency curve of hydraulic turbine.
