针对梯级水库防洪任务和边界条件发生的变化,建立了一种确定梯级水库防洪库容分配的数学模型,耦合水库电力调度优化、防洪效益优化等多种目标,把梯级水库预留的防洪库容最小作为约束条件,采用逐次优化算法求解出使梯级水库发电效益最大的非劣解集.以清江干流梯级水库为例,确定水布垭和隔河岩水库防洪库容的最优分配策略.在水布垭预留5亿m3和隔河岩预留不小于1.5亿m3防洪库容的前提下,若发生100年一遇的洪水时,隔河岩水库的最高调洪水位不会超过200m,可以满足防洪安全.该研究为梯级水库防洪库容分配提供了一种新的探讨思路.

实时洪水预报精度较高是实施汛限水位动态控制的基础,其不确定性又是动态控制的主要风险源.针对洪水预报不确定,采用贝叶斯水文不确定性处理器将确定性预报转化为概率预报;针对入库洪水预报精度较高,建立了考虑未来洪水大小的三峡水库汛限水位实时控制模型.应用结果表明,相对于原设计调度方案,实时动态模型根据预报洪水大小执行不同的预蓄预泄策略,在不增加防洪风险的前提下可显著地提高水库的发电效益.基于贝叶斯修正的概

水库的调蓄作用,改变了其下游天然洪水的水文情势,直接影响下游断面的设计洪水.以清江流域梯级水库为例,通过基于Copula函数的条件期望和最可能地区组成,结合规范采用的同频率地区组成方法,拟定了五种水布垭水库和区间流域洪水组合方案,推求受水布垭水库调蓄影响的隔河岩断面设计洪水.计算结果表明:与天然情况相比,考虑水布垭水库调蓄的不同重现期隔河岩断面设计洪水均减小.削减最大的是条件期望组合Ⅰ方案,最小的
