三里坪水利枢纽发电机组选型设计

Turbo-generator unit selection of Sanliping Hydropower Station

三里坪电站水轮机在某些运行条件下的运行稳定性将受到影响,因此,在水轮机设计参数选择时,应将水轮机运行稳定性放在首位。在分析影响水轮机运行稳定性参数的基础上,比较了几种水轮机不同运行工况下的运行指标,并考虑电站厂房结构及机组造价等因素,最终确定了最适合三里坪水利枢纽的水轮机型号。针对所选的水轮机型号,提出了改善水轮机运行稳定性的措施。

The turbine operation stability of Sanliping hydropower station will be influenced under some condition.Therefore,in the parameter selection of turbine,its operation stability should be put at the first place.Through analyzing the parameters influencing the turbine operation stability and comparing the operation indexes of several types under different working conditions,as well as considering the structure of powerhouse and the cost of generator-unit,the most suitable turbine type was determined for Sanliping Hydropower Station.
