摘要
通过理论推导,研究了水轮机综合特性系数对调压室稳定断面的影响,即水轮机运行中不同工况点效率的相对变化对调压室稳定断面的影响.得出了最危险的调压室稳定断面取决于设计水头,并通过实例得到验证.
The effect of turbine characteristic on stable sectional area of surge tank can be expressed by the synthetic characteristic coefficient of turbine,it shows the effect of turbine efficiency.Based on the analysis on the variation of the characteristic curve for middle or high specific speed turbine,this paper demonstrates that the largest stable sectional area of surge tank is not dependent on the lowest water head of hydroelectric plant but the design head.
