实时汛限水位动态控制研究

摘要

汛限水位动态控制是发挥水库兴利和防洪效益的最有效途径.为提高洪水资源利用率,运用预泄能力约束法确定某水库汛限水位动态控制的控制域,阐述预泄回充法和预蓄预泄法的基本思想和数学表达,讨论这2种方法在某水库汛限水位动态控制中的应用并分析该过程中带来的风险.分析结果表明,实行汛限水位动态控制相对常规调度能抬高汛限水位,增加水库蓄水,解决水库防洪与兴利之间的矛盾.%Dynamic control of limited water level is the most effective way to develop reservoir and flood control benefit.In order to improve the utilization of flood resources, using the pill capacity constrained pre-discharge to make sure the control sphere of the reservoir limited elevation realtime dynamic control and expound the basic idea and mathematical expression of the preven-rechage and pre-storage & pre-dischage.The application of these two measures in reservoir limited elevation realtime dynamic control was discussed and the risk during this period was analyzed.The results showed that compared with conventional reservoir operation, reservoir limited elevation realtime dynamic control can increase reservoir limited elevation, add reservoir impoundment, and solve the conflict between reservoir flood control and benefit.
