[Abstract]:[objective] to establish a multi-objective simulation model for the regulation of water and sediment in the upper reaches of the Yellow River, and to determine the adjustable water volume in the upper reaches of the Yellow River, in order to analyze the water transfer potential of cascade reservoirs in the upper reaches of the Yellow River. Effective regulation of water and sediment in the upper reaches of the Yellow River provides guidance. [methods] considering the objectives of flood prevention, water supply, power generation and sediment transport, under the conditions of known water supply and water supply, the ideal adjustable water volume for Longyangxia and Liujiaxia Reservoir is considered. In this paper, four operation modes of regulating water quantity and power generation by water and electricity are measured, and the simulation model of combined operation of Longyangxia and Liujiaxia reservoirs in the upper reaches of the Yellow River is established, and the model is solved by self-iterative simulation optimization algorithm. The adjustable water volume of cascade reservoirs in the upper reaches of the Yellow River is determined. [results] through the comparative analysis of the adjustable water quantity and the power generation efficiency under various operation modes, it can be seen that the adjustable water volume under the ideal adjustable water quantity mode can meet the requirements of Lanzhou section water supply. However, the power generation requirements of Longyangxia Hydropower Station are not met, the power generation and water supply under the actual adjustable water operation mode are not up to the design value, and the water supply guarantee rate of Lanzhou section reaches the design value under the water fixed power operation mode. Although the guaranteed output of Longyangxia power station has been improved, it has not reached the design value, and the water fixed power operation mode can realize the water supply and power generation target simultaneously. However, considering the shortage of water resources in the Yellow River Basin, the contradiction between supply and demand has intensified, The practical operation mode of cascade hydropower stations in river basins has changed from "fixing water by electricity" to "fixing electricity by water" at the beginning of the design period. The benefit of power generation should be considered on the basis of priority to meet the demands of water supply in the basin. Therefore, it is recommended to adopt the adjustable water quantity under the water fixed electricity mode, and the cumulative water transfer capacity for many years is 15.922 billion m3. [conclusion] the adjustable water quantity in the upper reaches of the Yellow River under the water fixed electricity mode is reasonable and feasible, and the cascade reservoirs in the upper reaches of the Yellow River have strong water and sediment regulation potential. When the water supply is less than 4 billion m3 in the coming year, the water and sediment can be adjusted once in 3 years on average, and 1 or 2 times in the year of Tefeng.
