摘　　要：以厄瓜多尔德尔西水电站的水轮机机型及机组参数的选择计算为基础,对500 m水头段采用混流式水轮机及水斗式水轮机进行了机组参数水平、设计制造难度、机组运行稳定性、维护性以及投资等综合比较。参考目前该水头段内的机型应用情况,最终推荐了水斗式水轮机,并在选定的机型下,结合目前中国大中型水轮机制造厂对于本水头段水斗式机组的设计、制造能力,对比计算最终选定该电站最佳的水轮机喷嘴数及主要技术参数。Based on the calculation and selection of turbine type and unit parameters for the Delsi hydropower project in Ecuador,comprehensive comparison was made for Francis turbine and Pelton turbine at 500m head in respects of unit parameter level,design and manufacture difficulty,unit operation stability,maintenance and investment.According to the application of turbines in this head range,Pelton turbine was finally recommended.In case of the selected type of turbine and on the basis of design and manufacture capability of turbine manufacturers in China,the optimal number of nozzles and main technical parameters for the project are finalized through comparison and calculation.
