分层型水库水量水质综合优化调度的研究

Optimal operation for stratified reservoir considering both water volume and quality

本文在分析水库水温、水质与水库取水建筑物关系基础上,建立了分层型水库水量水质综合优化调度数学模型,并以西安市黑河水库为例,进行了求解与计算。结果表明,该数学模型概念清晰,结构合理,计算精度较高,且优化迭代计算速度较快、占计算机内存量小,避免了动态优化中的“维数灾”。可供分层型综合利用水库在规划,设计,管理等阶段水量水质优化调度中使用。

Based on the analysis of the relationship between water volume, quality, and structure of reservoir, an optimal operation model considering both water volume and quality was developed for stratified reservoir. The model can be solved by the method of PAPOA. As an example, the model was applied to Heihe Reservoir in Xi'an. It was demonstrated by the case study that the model has resonable structure and physical meaning and the PAPOA method for solving the model has the advantages of relative small storage occupation and fast convergence when iterative computing with high accuracy, thus avoid the 'hazard of dimension'. The model may be applied to optimal operation of reservoir in the stages of planning, design, and operation.
