考虑多源入库水出库水的三门峡-小浪底水库汛期联合优化调控
Joint Optimal Regulation of Sanmenxia-Xiaolangdi Reservoir in Flood Season with Multi-Source Water Inflow and Outflow
摘要
Abstract
The joint operation of Sanmenxia-Xiaolangdi reservoir is a key link in the water and sediment regulation of the Yellow River.In or-der to better explore the potential of the joint optimal regulation of Sanmenxia-Xiaolangdi reservoir and improve the effects of water and sedi-ment regulation,we conducted a study on joint optimal regulation based on multi-source water inflow and outflow.The process of rainfall,e-vaporation,tributary inflow and water use in the Sanmenxia-Xiaolangdi reservoir in the flood season of 2020 were analyzed.Then,a joint op-timal operation model of Sanmenxia-Xiaolangdi reservoir with multi-source water inflow and outflow was established,by taking the comprehen-sive benefit of power generation and sediment discharge as the objective function.The results show that a)the contribution of secondary inflow water,such as rainfall,inflow water of tributaries,evaporation and water intake,to the water volume of Sanmenxia Reservoir and Xiaolangdi Reservoir is 271 million m3 and-85 million m3,respectively.The inflow water is mainly concentrated in the flood season,while the outflow water is relatively uniform throughout the year.b)The secondary water of Sanmenxia Reservoir accounts for about 36%of its effective reser-voir capacity,which will affect the joint optimaization regulation of Sanmenxia-Xiaolangdi reservoir.c)Sediment emissions are increased by Sanmenxia-Xiaolangdi reservoir joint optimization regulation with multi-source inflow and outflow,and the power generation benefit of Xia-olangdi Reservoir is increased by about 25.994 million Yuan.关键词
