摘要: 本文以安康水库为例,通过对入库洪水的年际、年内变化和地区组成规律进行分析,运用投影寻踪法进行洪水分类,制定了分类洪水调控方案。在不降低原设计防洪标准的前提下,分类洪水调控方案与常规调度方案相比,在涨水阶段可有效地抬高水库发电水头以增加发电量,在退水阶段可提前把库水位降低至汛限水位以迎接下一场洪水的来临;根据安康水库的水雨情预报信息,灵活的选择调度参照方案,为应对各种类型暴雨洪水的防洪调度提供技术支撑和决策参考。

Abstract: Taking Ankang reservoir as an example, this paper analyzed annual runoff variation and distribution as well as regional composition of inflows for Ankang reservoir. The projection pursuit method was applied to classified flood events and operation schemes of Ankang reservoir were proposed. It is shown that classified flood operation scheme can generate more hydropower by raising reservoir water level during flood rising periods and draw down water level to flood control limiting water level during flood recession periods in order to prepare storage for next coming flood without reducing original flood prevention standards. The proposed scheme is based on the rainfall and runoff forecasting information and different reference schemes, which can provide scientific support for decision making in various types of practical operation.
