【摘要】：水库在汛期使用单一汛限水位有利于保障水库的防洪安全,却大大降低了调度的灵活性和发电效益。对于多沙水库,在进行汛限水位动态控制的研究时,也应对泥沙因素予以考虑。为制定合理的多沙水库汛限水位动态控制方案,先采用预泄能力约束法,基于一维非均匀流不平衡输沙模型,选定水库汛限水位分期动态控制的范围,而后依据汛限水位动态控制预蓄预泄的基本原理,拟定某多沙水库的汛限水位实时动态控制方案。结果表明:在保证防洪安全和冲沙调度的前提下,对水库实施汛期分期及汛限水位动态控制方案,能够有效地提高水库的兴利效益。
[Abstract]:The use of a single flood limit water level in the flood season is conducive to ensuring the flood control safety of the reservoir, but it greatly reduces the flexibility of operation and the efficiency of power generation.The sediment factors should also be taken into account in the study of dynamic control of flood limit water level.In order to establish a reasonable dynamic control scheme for flood limit water level of multi-sediment reservoir, the pre-discharge capacity constraint method is adopted first, and based on one-dimensional non-uniform flow unbalance sediment transport model, the range of reservoir flood limited water level dynamic control by stages is selected.Then, according to the basic principle of dynamic control of pre-storage and pre-discharge of flood limited water level, the real-time dynamic control scheme of flood limited water level of a certain sand reservoir is worked out.The results show that, on the premise of ensuring flood control safety and sediment flushing operation, the reservoir can be effectively improved by stages in flood season and dynamic control scheme of flood limit water level.
