广西高水头水电站的规划与实践

广西高水头水电站的规划建设从1958年开始,首先建成的是玉林市大容山水电站,设计水头224 m,初期装机6 480 kW,后增加引水流量,扩机至11 160 kW,至今运行良好;20世纪90年代以来高水头电站的规划、建设进入了一个高潮,以天湖水电站一期为代表,设计水头1 074 m,装机30 000 kW,年发电量9 610万kW*h,于1992年建成投产,运行良好.据不完全统计,至2001年底广西已建成水头200 m以上的水电站80座,装机25.8万kW,年发电量11.8亿kW*h,为广西农村电气化建设,生态环境保护、社会可持续发展做出了重大贡献.

Planning and practice of high-head hydropower plants in Guangxi

The planning and construction of high-head hydropower plants started from 1958 in Guangxi.The first completed project is Darongshan hydropower plant in Yulin City,with a design head of 224m,an installed capacity of 6480kW at initial-stage and 11160kW after expansion by increase of diversion flow,and operating well up to now.The planning and construction of high-head hydropower plants have seen an upsurge since 1990s with the first-stage work of Tianhu hydropower plant as the representative which has a design head of 1074m,an installed capacity of 30000kW,an annual energy output of 96.1 million kW.h,was put into operation in 1992 and has been operating well.According to incomplete statistic,80 hydropower plants each with a head not less than 200m,with a total installed capacity of 258 thousand kW and an annual energy output of 1.18 billion kW.h had been constructed in Guangxi by the end of 2001,which had contributed greatly to the rural electrification construction,ecological environment protection and sustainable social development in Guangxi.
