摘　　要：初步设计阶段选择大藤峡大型轴流转桨式水轮机参数时,采用多种统计公式计算、统计曲线进行对比分析,通过项目资料收集、向水轮机设计制造厂商征询等方法,确定水轮机比转速、单位流量、单位转速等模型参数;针对不同单机容量和左右岸布置不同机组台数的多个方案进行综合技术经济比选。在充分征询、分析研究和计算基础上提出推荐的水轮机参数。经过左岸三台机组招标定厂后,通过水轮机模型验收试验核定的真机参数与初步设计阶段推荐参数对比验证,得出大藤峡大型轴流转桨式水轮机参数选择合适可行的结论。A number of statistical formulas and statistic curves were adopted for comparison of parameters of large Kaplan turbine for Datengxia Hydraulic Project during the preliminary design stage.Based on material collection and consultation to the designer and manufacturers,comprehensive technical and economic comparison and selection were conducted to define the model parameters such as specific speed of turbine,rate of flow and unit speed.Parameters of the turbine were finalized based on detailed consultation,calculation and studies.Contrast verification of true machine parameters was verified by hydraulic turbine model acceptance test with proposed parameters in the preliminary design were processed,after the final selection of manufacturers for the three units on the left bank.It indicates that the parameters for large Kaplan turbine of Datengxia Power Plant are feasible.
