基于旱限库容的水库优化调度策略研究——以广东省东江流域为例

Reservoir Optimal Operation Model Based on Drought-Limited Storage Capacity—A Case Study of the Dongjiang River Basin in Guangdong Province

摘要: 针对干旱“发展缓慢”和“可预见性差”的特点，本文提出了一套基于旱限库容的水库优化调度策略，并以2020~2021年广东省东江流域抗旱过程为例，结合抗旱实际，提出了降低控制断面目标流量、减少出库流量等一套调度规则。仿真结果表明，按此优化策略的水库调度过程能够有效延长可利用水量时间，使控制断面流量更加平稳，同时显著改善水库运行工况的安全性。研究成果为抗旱调度规则的制定和求解提供了新思路，对提升干旱时期的水资源合理利用水平和水库科学调度能力具有重要意义。

Abstract: In response to the characteristics of drought such as “slow development” and “low predictability”, this paper proposes a set of reservoir optimal operation strategies based on drought-limited storage capacity. Taking the drought resistance process in the Dongjiang River Basin of Guangdong Province from 2020 to 2021 as an example, combined with the actual drought resistance situation, a set of operation rules are put forward, including reducing the target flow of the control section and decreasing the outflow. The simulation results show that the reservoir operation process under this optimized strategy can effectively extend the water available period, make the flow of the control section more stable, and significantly improve the safety of reservoir operation conditions. The research results provide new ideas for the formulation and solution of drought resistance operation rules, and are of great significance for improving the appropriate utilization level of water resources and the scientific operation capacity of reservoirs during drought periods.
