摘　　要：针对水库群蓄水优化调度中存在水流滞时导致长期调度中水量不平衡以及使水库蓄水量产生滞后性的问题,基于水流滞时对优化蓄水问题与优化发电量问题中产生影响的差异进行分析,调整计算方式只考虑相邻上级水库出流产生的水流滞时的影响,提出了考虑水流滞时的水库群蓄水优化调度模型。并结合逐步优化法对模型分块求解,选取安肇新河流域具备兴利条件的各滞洪区为例,验证模型有效性。结果表示:此模型满足水库蓄水需求,体现了受水流滞时影响的蓄水效益,在保障运行安全的前提下发挥水库群蓄水潜力。Aiming at the problem of water delay time in the optimal scheduling of reservoirs,which leads to unbalanced water volume in the long-term scheduling and lagging of reservoir storage,based on the difference in the impact of water delay time on the optimization of water storage and the optimization of power generation.For analysis,the adjustment calculation method only considers the impact of the water delay time caused by the outflow of the adjacent upper reservoir,and proposes a reservoir group storage optimization scheduling model considering the water delay time.Combined with the stepwise optimization method,the model is solved in blocks,and the reservoir with beneficial conditions in the Anzhao New River Basin are selected as examples to verify the effectiveness of the model.The results show that this model meets the water storage demand of the reservoir,reflects the water storage benefit affected by the water delay time,and exerts the water storage potential of the reservoir group under the premise of ensuring the safety of operation.
