摘　　要：基于大系统聚合分解理论,建立了梯级水库汛限水位联合运用和动态控制模型,在不降低梯级水库防洪标准的前提下,最大限度地发挥梯级水库的兴利效益。以清江流域为例,选取丰、平、枯水典型年汛期3h的资料,分别按原设计方案和梯级水库汛限水位联合运用方案进行调度运行。结果表明:与原设计汛限水位方案相比,梯级水库汛限水位联合运用方案按库容最优分解策略动态控制,汛期发电量可增加1.79亿kW.h,增幅为4.51%;洪水资源利用率提高了2.73%。因此开展梯级水库汛限水位联合运用调度,可显著地提高水库的综合利用效益。This paper develops a joint operation and dynamic control model of flood limited water levels for optimization of cascade reservoirs′ economic benefits without lowering design flood protection standards,based on large-scale system decomposition and coordination theory.This model was tested in a case study of the Qingjiang cascade reservoirs by comparing the dynamic joint optimization with the design operation,using flood data series of three-hours for typical wet,normal and dry years.Results show that the proposed model generated an extra power output of 179 million kW·h or a 4.51% increase and a 2.73% increase in flood water use,relative to the design operation scheme.Thus,joint operation of flood limited water levels greatly enhances comprehensive benefits of cascade reservoirs.
