针对降雨量级预报的串联水库汛限水位动态控制研究

Research on Dynamic Control of Cascade Reservoir Flood Limit Water Level with Magnitude Rain Forecast

水库传统汛限水位控制以"一刀切"的方式,造成洪水资源的浪费。水库汛限水位动态控制能够实现水库洪水资源化、提升水库防洪能力,发挥水库综合效益。以浙江省分水江水库为例,从水库实际情况和易于调度角度出发,建立确定串联水库汛限水位动态控制域的约束指标体系,提出针对降雨量级预报的调度方案,并利用水库预报系统进行汛限水位动态控制的风险控制,形成了便于实际操作的串联水库汛限水位动态控制方案。

＂One-size-fits-all＂operation is employed in the traditional flood control of reservoir,which causes the waste of flood resources during flood season. The dynamic control of reservoir flood limit water level can realize the utilization of flood resources,improve the flood control capacity of reservoir and exert the comprehensive benefit of the reservoir. Based on Fenshuijiang Reservoir in Zhejiang Province as an example,from the actual condition and easy-to-operate perspective,this paper establishes a dynamic control domain constraints index system of cascade reservoir flood limit water level,proposes a dynamic control operation with magnitude rain forecast,uses reservoir flood forecast system for risk control of limited water level dynamic control,and forms a practical dynamic control operation of cascade reservoirs flood limit water level.
