【摘要】：隨著水資源在供需上產生的矛盾日益尖銳,水資源的缺乏已經成為制約我國經濟發(fā)展的嚴重性問題。因此如何合理地分配水資源量、實現(xiàn)水資源的可持續(xù)利用成為當下人們普遍關心的問題。灤河作為我國北方地區(qū)水資源較為豐沛的河流之一,是華北地區(qū)重要的河流之一。引灤工程是灤河流域上的大型水利工程。本文就現(xiàn)有工程基礎上,對引灤工程中的潘家口、大黑汀和桃林口等水庫群進行聯(lián)合供水調度主要研究內容包括以下幾個方面:(1)闡述了本文的研究背景及研究意義,對國內外在該領域的研究歷史及現(xiàn)狀進行簡單介紹,并就其發(fā)展趨勢進行闡述。提出本文的研究內容及研究路線。(2)介紹研究區(qū)流域的基本情況。對灤河流域的已建工程及工程運行情況進行進一步全面的介紹。(3)根據(jù)灤河下游水庫群各水庫、區(qū)間歷年來水資料,分析各水庫的入庫徑流、區(qū)間入流的變化規(guī)律及變化趨勢。(4)總結對比各種需水量預測的方法,對比各個方法的優(yōu)缺點。對受水區(qū)的水資源進行需水預測。(5)在(1)-(4)工作的基礎上,根據(jù)現(xiàn)有工程的實際情況建立潘家口、大黑汀、桃林口等水庫群的聯(lián)合供水優(yōu)化調度模型。(6)針對遺傳算法的不足點,在算法中改進動態(tài)變異率及動態(tài)交叉率。再運用改進后的遺傳算法對水庫群供水優(yōu)化調度模型進行計算,得出在不同來水頻率的情況下的供水優(yōu)化調度方案,并對得出的結果進行分析總結。
[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.
