百米水头段水轮机主要参数选择浅析

以大渡河金川水电站水轮机参数的选择计算为基础,结合中国已建的百米水头段机组参数为参考依据,且调研目前国内大中型水轮机制造厂对于百米水头段水轮机转轮的设计、制造能力,分析现阶段百米水头段混流式水轮机主要参数的发展水平。在现阶段金川水电站机组尚未定货的情况下,结合上述分析及统计曲线,保证在电站的可研设计参数选择时既能体现目前的先进水平,又要在合理的范围之内,以保证最大的效果费用比。最终通过分析、论证,初步确定金川水电站水轮机主要参数。

Discussion on main parameters selection for turbines at hundred head section

Based on calculation and selection of turbine parameters for Jinchuang hydropower project on the Dadu River,and taking the parameters of existing units at hundred head section in China as reference basis,the design and manufacture capability of manufacturers of large and middle scale turbines are researched and the current development level of main parameters of Francis turbines are analyzed.In order to ensure the parameters selection at feasibility study stage to reach the advanced level,be in the reasonab...
