Study on Parameter Selection for Hydraulic Turbine of Goupitan Hydropower Station

构皮滩水电站水轮机工作水头高、机组出力大,水轮机的参数选择难度大。本文在对构皮滩水电站水轮机的水力参数如水轮机的比转速和比速系数、水轮机的单位流量、水轮机的单位转速和效率、水轮机的空蚀性能、水轮机的水力稳定性进行综合分析的基础上,确定了该电站较合理的水轮机参数。

For operating head of hydraulic turbine is high and unit output is great,the parameter selection for hydraulic turbine of Goupitan Hydropower Station is difficult.Based upon the synthetically analysis of hydraulic parameters,such as specific speed and its coefficient,unit flow,unit rotational speed and efficiency,level of cavitation,hydraulic stability,the parameters of hydraulic turbine were fixed rationally.
