龙羊峡水库兼顾中下游供水运用初步研究

借助于“黄河流域水资源模拟模型“,采用长系列模拟方法计算了龙羊峡水库兼顾中下游供水的效益。初步研究表明,龙羊峡水库可以在一定程度上兼顾中下游用水,特别是在枯水年能够有效减少干流缺水,虽然这是以上游梯级发电效益减少为代价,但代价甚微。

A Study on the Operation of Longyangxia Reservoir Considering Water Supply for the Lower Reaches of Yellow River

As the only reservoir of overyear regulation in the Yellow River,Longyangxia Reservoir can take important roles in the unit water operation of the river.The operation of Longyangxia Reservoir,which considering water supply for the lower reaches means its water supply area is enlarged.In this case,what is the influence on the power generation of upper cascade power stations?How much is the water supply capacity added?All these are the focus questions considered by water and power departments.Based on"Yellow River Water Resources Simulation Model",this paper uses long series simulation method to calculate the benefits of the operation of Longyangxia Reservoir considering water supply for the lower reaches.The study indicates that Longyangxia Reservoir operation can consider the water supply for the lower reaches.In the dry years,it can reduce water shortage of the trunk steam as affe cted at the expensive of the fall of power.However the expensive is little.
