广西农村水电站增效扩容改造技术及效益分析

Technical and benefit analysis for efficiency enhancement and capacity expansion of rural hydropower station

许多20世纪50-60年代修建的水电站受当时的设计、技术条件及工艺水平的限制,加上水电站经过几十年的运行,存在着不同程度的问题。本文通过对柳州市三江侗族自治区县厘金滩水电站、桂林市青狮潭电厂、崇左市大新县那岸水电站增效扩容改造工程等案例的技术分析,论述实施水电站增效扩容改造后产生的效益。

Limited by the design and technical conditions as well as the manufacture level at that time,the hydropow⁃er stations constructed from 1950s to 1960s have problems of different degrees after decades of operation.Based on the technical analysis of several hydropower station efficiency enhancement and capacity expansion projects such as Lijintan Hydropower Station at Sanjiang Dong Autonomous County of Liuzhou City,Qingshitan Hydropower Plant in Guilin City and Naan Hydropower Station at Daxin County of Chongzuo City,the author demonstrated the benefits of hydropower station capacity expansion project.
