Analytical Expressions of Basic Force Characteristics of Bulb Hydraulic Turbines

根据叶片式水力机械的广义基本方程式和贯流式水轮机导叶布置的几何特征，建立了一组基本力特性的解析表达式。该方程组适用于贯流式水轮机装置的稳定工作过程和过渡过程状态的分析与计算。用该方程组计算一些贯流式水轮机装置的过渡过程，结果表明它是正确和适用的。

According to the universal basic equation of hydraulic turbomachinery and the guide vane arrangement geometry of bulb turbine, a system of analytical expres-sions of basic force characteristics is developed. This system can be used for analyzing and calculating the steady working process and the transient conditions of bulb turbine installations. The application of this system for calculating the load rejection transients of bulb turbines has proved that those expressions are correct and suitable.
