水库是水资源综合开发和管理的重要基础设施之一，在防洪和涵养水源方面发挥着越来越重要的作用。水库汛限水位的动态控制是兼顾流域防洪、水力发电和水资源综合利用的有效途径。本文将单水库和梯级水库的FLWL动态控制模型扩展到混合水库系统。该模型由单水库动态调度模块、梯级水库动态调度模块和混合梯级水库系统联合调度模块组成。以长江流域的三峡、清江梯级水库为例进行了实例研究。利用代表性水文年的3小时入流资料序列对模型进行了检验。结果表明，该模型能有效地兼顾防洪和水力发电。在不降低原设计防洪标准的前提下，联合调度和动态控制可为混合梯级水库系统多发电26.4 × 108kW·h（3.47%），提高三峡水库和清江梯级水库水资源利用率3.72%和2.42%。
Reservoirs are one of the most efficient infrastructures for integrated water resources development and management; and play a more and more important role in flood control and conservation. Dynamic control of the reservoir flood limiting water level (FLWL) is a valuable and effective approach to compromise the flood control, hydropower generation and comprehensive utilization of water resources of river basins during the flood season. The dynamic control models of FLWL for a single reservoir and cascade reservoirs have been extended for a mixed reservoir system in this paper. The proposed model consists of a dynamic control operation module for a single reservoir, a dynamic control operation module for cascade reservoirs, and a joint operation module for mixed cascade reservoir systems. The Three Gorges and Qingjiang cascade reservoirs in the Yangtze River basin of China are selected for a case study. Three-hour inflow data series for representative hydrological years are used to test the model. The results indicate that the proposed model can make an effective tradeoff between flood control and hydropower generation. Joint operation and dynamic control of FLWL can generate 26.4 × 108kW h (3.47%) more hydropower for the mixed cascade reservoir systems and increase the water resource utilization rate by 3.72% for the Three Gorges reservoir and 2.42% for the Qingjiang cascade reservoirs without reducing originally designed flood prevention standards.
