水库防洪完全补偿调度方式研究
|
摘要
完全补偿调度方式(CCO)是水库防洪规划和实时调度广泛应用的调洪方式。对于一个水库和单防洪控制点所组成的防洪系统,以水库防洪库容最小为目标函数、下游河道水流演进和补偿调度期间水库出流下限等为约束,建立具有通用性的基于完全补偿调度方式的线性规划数学模型。通过一个水库两个防洪控制点和多个典型设计洪水的实例应用,揭示了防洪控制点流量过程特征、水库补偿特征参数(效果、时间及库容)变化规律、及固定泄流方式(FDO)和错峰调度方式(SFPO)与完全补偿调度方式的关系,形成了错峰调度方式参数的推求方法,明晰了水库补偿期间出流下限对出库流量、防洪库容及错峰起始流量的影响规律。
Complete Compensation Operation(CCO) is widely used in flood control planning and real-time operation. The basic connotation and essential characteristics of CCO are of great theoretical and practical value. As a flood control system consisted of a reservoir and a downstream flood control point,a general linear programming model with the objective function of minimum flood control volume using complete compensation operation is established,considering the downstream river evolution and the lower limit of discharge as constraints. A case study of a single reservoir and two downstream flood control points reveals the flood process characteristics of flood control points,the change rules of CCO characteristic parameters(effect,time and flood control volume) and the relationship among CCO 、FDO and SFPO. This paper proposes a method to calculate the parameters of SFPO. meanwhile,it also clarifies the effects of lower limit of discharge on discharge,flood control volume and the start-stop time of SFPO.
