洋河滩水电站增效扩容改造技术方案及效益分析

Technical Scheme and Benefit Analysis of Synergism and Capacity Enlarging for Yanghetan Hydropower Station

针对洋河滩水电站竖井贯流水轮发电机组老化、效率偏低等问题,提出了立轴定浆式、卧式两种机组更新改造技术方案,并通过比选获得了较优的技术方案,提高了发电出力和效率,进而计算了改造后的效益,同时给出了增效扩容的辅助技术措施,对农村小水电站增效扩容及同类电站改造具有借鉴意义。

Aiming at the problems of shaft tubular turbine in Yanghetan hydropower station, such as ageing and low efficiency, this paper puts forward two technological transformation projects including vertical axis fixed blade propeller and horizontal unit. Optimal scheme is obtained by contrast and choice, which improves power generation and efficiency. And then the reformed benefit is calculated. At the same time, the auxiliary technical measure of synergism and capacity enlarging is put forward. Therefore, it will be of benefit to synergism and capacity enlarging of rural small hydropower and improvement of similar power station.
