一、刘家峡、盐锅峡水电站概况刘家峡水电站位于甘肃永靖县黄河干流上,控制流域面积为18,18万平方公里,多年平均流量866米~3/秒,水库正常高水位1735米,总库容57亿米~3,有效库容41.5亿米~3,具有不完全年调节性能.电站保证出力40万千瓦,安装四台HL001—LJ一550和一台HL008—LJ—550型水轮发电机组,总容量为122.5万千瓦,多年平均年发电量57亿度.1980年验收及最近核算,近期保证出力为37万千瓦,电站可调出力为116万千瓦,年平均可用发电量47.3亿度.除发电外,还承担防洪、灌溉、防凌、城市工业供水及旅游等任务.
I. Overview of Liujiaxia and Yanxiaxia Hydropower Plants Liujiaxia Hydropower Station is located on the main stream of the Yellow River in Yongjing County, Gansu Province. The control basin covers an area of 181,800 square kilometers with an average flow of 866m ~ 3 / s for many years. The normal elevation of the reservoir is 1,735m and the total storage capacity 570000000 ~ 3, effective storage capacity of 4.15 billion meters ~ 3, with incomplete annual regulation performance.Power plant to ensure output of 400000 kilowatts, the installation of four HL001-LJ a 550 and a HL008-LJ-550 hydroelectric generating set, With a total capacity of 1.225 million kilowatts, annual average annual generating capacity of 5.7 billion degrees .1980 acceptance and recent accounting, recently promised to contribute to 370,000 kilowatts, power station adjustable output of 116 million kilowatts, the average annual generating capacity of 4.73 billion degrees available. Power generation, but also assume flood control, irrigation, anti-Ling, urban industrial water supply and tourism tasks.
