基于预报信息和泄流能力约束的库水位动态控制方法与应用

Dynamic operation of reservoir normal elevation based on rainfall forecast and constrained pre-discharge capacity and its application

水库汛限水位动态控制对防洪与兴利蓄水都十分重要。本文分析了水库汛限水位动态控制研究的现状,针对应用广泛的预泄能力约束法在应用中存在的问题,重点研究了该方法的实时应用。首先阐述了该方法的基本思想,并给出其数学描述和计算过程;然后以碧流河水库流域2005年"8.8"洪水实际调度为背景,介绍了该方法的实时应用过程。结果表明,该方法具有较强的可操作性,可推广应用到我国北方其他调节性好的水库的实时防洪调度中。

Dynamic operation of reservoir normal elevation in flood season（RNES） is an important new technique for flood control and water resources utilization,and a significant progress in this technique is made in recent years.This paper proposes a pre-discharge and pre-storage method for RNES dynamic operation,demonstrating the basic idea,mathematic description and calculation procedure,and focuses on the real-time application of this new method to a study case of Flood 8.8 of Biliuhe watershed in 2005.Results show that the method can conserve more water resources without adding flood risk in comparison with the traditional operation methods.The proposed method can be applied to the flood operation of other reservoirs.
