Embodiment Construction

[0107] Attached below figure 2 , taking the Jinniushan reservoir group and its water delivery channel system in Nanjing City, Jiangsu Province as an example to further illustrate the present invention.

[0108] (1) Through actual measurement or consultation with the irrigation district management department, collect the relevant data required for calculation, including:

[0109] ① Divide the scheduling period (hydraulic year) into 12 time periods by month;

[0110] ② Number the five reservoirs in the system respectively, Jinniushan Reservoir number i=1, Maoying Reservoir number i=2, Tanggong Reservoir i=3, Nanyang Reservoir i=4, Zhaoqiao Reservoir i=5;

[0111] ③Collect reservoir inflow data

[0112] LS 1,t =[375,158,13,19,59,34,149,842,1358,1498,867,361] ten thousand m 3

Abstract

The invention belongs to the technical field of irrigation area water resource optimal allocation, and particularly relates to a water resource optimization scheduling method for hilly area long-vinemelon-bearing type multi-reservoir system. The method comprises the following specific steps: (1) searching and calculating required related data through actual measurement or consultation to an irrigation area management department; (2) system decomposition: decomposing the multi-reservoir system water resource optimal scheduling model into a plurality of single-reservoir subsystem water resource optimal scheduling models; (3) optimizing the single reservoir subsystem by adopting dynamic planning; and (4) aggregating the large systems by adopting dynamic planning, and finally obtaining an optimal scheduling scheme of the multi-reservoir system. According to the invention, a corresponding water resource optimal scheduling mathematical model is established. On the basis of the decomposition and aggregation theory, the subsystem model and the aggregation model are solved through dynamic programming, the minimum water shortage amount of a water receiving area in a certain water supply period and the corresponding optimal water supply amount and water abandoning amount process of all reservoirs can be obtained, seasonal water shortage of a multi-reservoir system is solved, and the utilization rate of water resources is increased.

Description

technical field [0001] The invention relates to a water resource optimization scheduling method for a multi-reservoir system in a hilly area, belonging to the technical field of water resource optimization allocation in irrigation areas. Background technique [0002] China's hilly areas are widely distributed, accounting for more than 70% of the country's land area, and its cultivated land accounts for about 50% of the country's total cultivated land area. Therefore, the development of hilly area agriculture is of great significance to ensuring national food security. The "long vines and melons" multi-reservoir irrigation system combined with storage, introduction and extraction is the crystallization of the wisdom of the working people in ancient Chinese hilly areas. Because the channel system looks like vines and the water storage project looks like melons, it got its name. The system can not only effectively adapt to the characteristics of the terrain, but also play the ...
