摘　　要：针对三峡和清江梯级水库群防洪补偿联合调度问题,建立了梯级单独和水库群联合防洪优化调度2种数学模型,运用改进的逐次渐进优化算法,引入动态惩罚函数处理约束条件,遵循"优化-验证-调整"的算法流程迭代求解.选取1954、1981、1982和1998年为典型年.结果表明:若选择最不利的1982年为典型年,荆江河段的防洪标准至少可分别提高到118年和136年一遇设计洪水;取4个典型年的调度结果平均值,则其可抵御的最大重现期设计洪水分别达到150、168 a.To solve the problem of optimal operation of jointed flood control for the Three Gorges reservoir and Qingjiang River cascade reservoirs,separated and jointed cascade operation of flood control models were established respectively.The models were solved by modified progressive optimality algorithm according to the procedure of ＂optimization -verification-adjustment＂;and their constraint conditions were treated by dynamic penalty function.Four typical years of 1954,1981,1982 and 1998 were selected to derive the design flood hydrographs.The results show that the Jingjiang River reach flood control standard can be raised to 118-year and 168-year design flood respectively based on 1982 typical year;and 150-year and 168-year design flood respectively based on the average of four typical years.
