设计代表年法在小摊水电站保证出力计算中的应用

Application of Design Representative Year Method in Calculation of Guaranteed Output for Xiaotan Hydropower Station

介绍了设计枯水年法推求年调节水电站的保证出力,在已知相应水位流量关系、正常蓄水位及死水位、设计枯水年来水等情况下,通过对枯水年径流序列进行供蓄水期的划分、径流调节、水能计算等,最后得到小摊水电站保证出力,保证出力为15.19万kW。

In this paper,the design low flow year method is introduced to calculate the guaranteed output of the annual regulating hydropower station.Under the condition that the corresponding water level and flow relationship,normal water level and dead water level are known,and the water from the design low flow year is known,the guaranteed output of XiaotanHydropower Station is finally obtained by dividing the supply and storage period of the low flow year runoff sequence,runoff regulation,water energy calculation,etc.,and the guaranteed output is 151900 kW.
