| 黄河水少沙多,河道内外用水矛盾突出,梯级水库群调度下供水、输沙、发电、生态等用水过程之间存在复杂的竞争与协作关系,协同调度是提升综合效益的重要途径。本文采用多尺度嵌套和多过程耦合方法,建立了融合供水、输沙、发电、生态等过程的黄河梯级水库群协同调度模型,研究以综合满意度为引导的优化求解方法,选取代表径流系列,提出多过程协同调度方案。结果表明,通过优化黄河梯级水库群蓄泄秩序和下泄过程,协调多用水过程的关系,能显著提高水库调度的综合效益:通过优化河段取水过程,实现了供水时空均衡,流域缺水率控制在11.6%~18.8%;优化水库拦沙-河道输沙过程,减少水库淤积0.65亿t,增加河道输沙1.16亿t,下游河道年均冲刷0.26亿t;优化梯级水库群发电下泄过程,增加发电量64.25亿kW·h;优化断面流量过程,增加非汛期生态水量4.88亿m3。本研究可为梯级水库多目标调度与流域综合管理提供方向性参考。 |

| The outstanding feature of the Yellow River is less water and more sand,so water use inside and outside the river is usually prominent contradictory.There is a complex competition and cooperation relationship between water supply,sediment transport,power generation,ecology and other water use processes under cascade reservoirs scheduling of the Yellow River,and collaborative scheduling is an important way to improve comprehensive benefits for cascade reservoirs.Using multi-scale nesting and multi-process coupling methods,a collaborative scheduling model for the Yellow River cascade reservoir group integrating water supply,sediment transport,power generation,ecology and other processes was established,and the optimization solution method guided by comprehensive satisfaction was studied.To represent the series,a multi-process cooperative scheduling scheme is proposed.The results show that by optimizing the storage and discharge order and discharge process of cascade reservoirs,relationship between multiple water use processes is coordinated,and comprehensive benefits are significantly improved:water intake process of the river reaches is optimized,water supply is balanced in time and space,and water shortage rate is controlled at 11.6%-18.8% in the basin.In the process of sediment retention in reservoirs and sediment transport in river channels,siltation in reservoirs was reduced by 65 million tons,sediment transport in river channels was increased by 116 million tons,and annual downstream erosion was 26 million tons,power generation and discharge process of cascade reservoirs on the Yellow River was optimized,and power generation was increased by 6.425 billion kWh.The section flow process was optimized to increase the non-flood season ecological water volume by 488 million m3.Overall,the research can provide a directional reference for the multi-objective dispatching of cascade reservoirs and integrated watershed management. |
