【摘要】：随着水资源在供需上产生的矛盾日益尖锐,水资源的缺乏已经成为制约我国经济发展的严重性问题。因此如何合理地分配水资源量、实现水资源的可持续利用成为当下人们普遍关心的问题。滦河作为我国北方地区水资源较为丰沛的河流之一,是华北地区重要的河流之一。引滦工程是滦河流域上的大型水利工程。本文就现有工程基础上,对引滦工程中的潘家口、大黑汀和桃林口等水库群进行联合供水调度主要研究内容包括以下几个方面:(1)阐述了本文的研究背景及研究意义,对国内外在该领域的研究历史及现状进行简单介绍,并就其发展趋势进行阐述。提出本文的研究内容及研究路线。(2)介绍研究区流域的基本情况。对滦河流域的已建工程及工程运行情况进行进一步全面的介绍。(3)根据滦河下游水库群各水库、区间历年来水资料,分析各水库的入库径流、区间入流的变化规律及变化趋势。(4)总结对比各种需水量预测的方法,对比各个方法的优缺点。对受水区的水资源进行需水预测。(5)在(1)-(4)工作的基础上,根据现有工程的实际情况建立潘家口、大黑汀、桃林口等水库群的联合供水优化调度模型。(6)针对遗传算法的不足点,在算法中改进动态变异率及动态交叉率。再运用改进后的遗传算法对水库群供水优化调度模型进行计算,得出在不同来水频率的情况下的供水优化调度方案,并对得出的结果进行分析总结。
[Abstract]:With the increasingly sharp contradiction between supply and demand of water resources, the lack of water resources has become a serious problem restricting the economic development of our country. Therefore, how to allocate water resources rationally and realize the sustainable utilization of water resources has become a common concern. As one of the rivers with abundant water resources, Luanhe River is one of the important rivers in North China. Luanhe River diversion Project is a large-scale water conservancy project in the Luanhe River Basin. Based on the existing projects, the main contents of this paper are as follows: (1) the research background and significance of this paper are described. This paper briefly introduces the history and present situation of research in this field at home and abroad, and expounds its development trend. The research content and route of this paper are put forward. (2) the basic situation of the river basin in the study area is introduced. The construction and operation of the Luanhe River Basin are introduced in detail. (3) according to the water data of the reservoirs in the lower reaches of the Luanhe River, the inflow runoff of the reservoirs is analyzed. (4) summing up and comparing various water demand forecasting methods and comparing the advantages and disadvantages of each method. (5) on the basis of (1)-(4) work, according to the actual conditions of the existing projects, the establishment of Panjiakou, Dagheting, The optimal operation model of combined water supply in Taolinkou and other reservoirs. (6) to improve the dynamic mutation rate and dynamic crossover rate in the algorithm for the deficiency of genetic algorithm. Then the improved genetic algorithm is used to calculate the optimal operation model of reservoir group water supply, and the optimal water supply scheduling scheme under different water frequency is obtained, and the results are analyzed and summarized.
