摘　　要：建立了混联水库群汛限水位联合运用和动态控制模型,在不降低水库群防洪标准的前提下,最大限度地发挥水库群兴利效益。以三峡梯级和清江梯级组成的混联水库群为例,选取丰、平、枯水典型年汛期6-7月资料,分别按照原设计方案、梯级汛限水位单独运用方案、库群汛限水位联合运用方案进行调度运行。结果表明:与原设计方案相比,采用梯级汛限水位单独运用方案时,多年平均发电量可增加8.13亿kW.h,增幅达到2.79%;采用库群汛限水位联合运用方案时,多年平均发电量可增加9.02亿kW.h,增幅达到3.10%。开展混联水库群汛限水位联合运用调度,可显著提高水库的综合利用效益。To obtain more economic benefits without increasing flood control risks, a real-time and dynamic operation model of flood limited water levels （FLWLs） for mixed multi-reservoirs was proposed and applied to a case study of the Three Gorges cascade and Qing River cascade reservoirs. The results show that the operational schemes of FLWLs for individual cascade reservoirs and mixed multi-reservoirs generate more power of 0. 813 billion kW·h （or 2.79% ） and 0. 902 billion kW·h （or 3.10% ） than that of the traditional design, respectively. Thus, it is proved that a dynamic joint operation scheme greatly improves the comprehensive benefits of cascade reservoirs.
