基于PSO的梯级水库联合防洪调度

在分析梯级水库联合防洪调度、上下游水库及防洪保护对象之间复杂的水文水力联系和水库群对防洪保护对象防洪补偿调度方式的基础上,建立了梯级水库联合防洪补偿调度模型,并提出了一种基于粒子群算法的模型求解方法。以湖南省资水流域上柘溪与金塘冲水库为例,根据不同典型年的地区洪水组合,通过模型求解拟定了梯级水库联合补偿调度原则。分析研究结果表明,这种基于PSO的梯级水库联合防洪调度原则是合理的,该模型能在一定程度上简化梯级水库联合防洪补偿调度的复杂性,为解决梯级水库联合防洪补偿调度提供了一条简洁有效的途径。

Flood control compensating operation of cascade reservoirs based on particle swarm optimization algorithm

Based on the analysis of complex hydrological and hydraulic relationship between cascade reservoirs， a multi reservoir flood control compensation model is developed in this paper. And the particle swarm algorithm approach is used for deriving flood control compensation rules. The flood control operation of the Zhexi and Jintangchong reservoirs on Zishui basin in Hunan Province is taken as an example for examining this model. For protecting Yiyang city which is the flood control protected object of these two reservoirs， the flood control compensation rules for these cascade reservoirs is derived based on nine floods of different typical years and different types， and the natural flood peak discharge of Yiyang city can be reduced to the safety discharge. Analysis results show that this principle of the flood control compensation regulation of cascade reservoirs based on the Particle Swarm Optimization algorithm (PSP) is reasonable, and can be used as a reference for the design of Jintangchong reservoir. This model can simplify the complexity of the flood control compensation regulation of the cascade reservoir group. In the case study， it is found that the proposed method is a usable approach for solving the flood control operation of cascade reservoirs.
