乌溪江梯级湖南镇水库年末消落水位研究

Study on year-end drawdown level of Hunanzhen Reservoir of Wuxijiang River cascade reservoir

本研究结合乌溪江梯级水库自身的特点,分别对其丰、枯流量系列进行了全梯级长系列连续径流调节计算,并建立了若干基于供水和发电的综合评价指标。通过对不同消落水位下这些评价指标的变化情况进行分析,确立了乌溪江梯级湖南镇水库的年末消落水位的合理取值范围,成果具有一定实用性。

Combined with the self-characteristics of Wuxijiang River cascade reservoir,the regulation of the long serial and continuous runoff of the whole cascade is calculated for its high and lower water level flow rate respectively,and then several water supply and power generation-based comprehensive evaluation indexes are established. Through the analysis on the changes of these indexes under various drawdown levels,the reasonable value selection range for the year-end drawdown level of Hunanzhen Reservoir of Wuxijiang River cascade reservoir is determined,which has a certain praticability.
