小型水电站机组合理选择与增容改造

The reasonable selection of water turbine generator units and the reformation of increasing capacity on small water power stations

通过对实例的分析、计算，阐述了不少农村小型水电站在进行水轮发电机组的选型设计工作中存在的问题，介绍了正确合理的选型设计方法，论述了小型立轴轴流式水轮机尾水管的选用，介绍了南丰县近年来对老电站进行分期分批更新改造、配套增容工作及所取得的显著效益。

By analyzing and calculating the example, this paper states the existingptoblems in the selecting-type design work of water turbine generator units inmany rural smail water power stations and introduces the reasooable method ofselecting-type design. It also illustrates the selection of watertail pipe on small-type vertical shaft axial flow water turbine. At last it introduces the replacingand reformation work of the old water power stations by stages and in groups, and the matching and increasing capacity work in recent years in Nanfeng county, These measures brought about noticeable benefitial result.
