Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0038] Dalian City, Liaoning Province is a city with severe resource-based water shortage. With the development of the city in recent years, the city’s water consumption has gradually increased, and the contradiction between urban supply and demand has intensified. The Nahe Reservoir has been unable to meet the city's water demand. In order to alleviate the pressure on the city's water supply, the Biliuhe Reservoir has diverted water from the Dahuofang Reservoir in Fushun City, which is relatively abundant but far away. Long-distance water transfer costs are high, and in order to make full use of local water resources, reservoir managers consider changing the existing river system connectivity pattern and further tapping the local water source capacity. Biliuhe Reservoir and Yingnahe Reservoir are the two most important local water supply sources. The ...

Abstract

The present invention discloses a reservoir connectivity analysis method based on multi-target analysis. The method comprises the following steps of S1 determining reservoirs and the basic situations of the reservoirs which are involved in a connecting engineering needing to be demonstrated; S2 designing corresponding connecting schemes according to the conditions, such as the reservoir distribution situation, the reservoir water supply tasks, etc.; S3 applying a multi-target decision method to establish a reservoir multi-target joint scheduling model; S4 adopting a multi-target genetic algorithm epsilon-NSGAII to optimize and obtain the multi-target tradeoff solution sets of the reservoir scheduling under the schemes; S5 utilizing the visualized analysis to compare the multi-target solution sets of the schemes, and evaluating the advantages and disadvantages of the multi-target solution sets of the schemes, thereby giving out a reservoir connecting feasibility analysis result. The reservoir connectivity analysis method based on multi-target analysis of the present invention fully considers a watershed hydrology compensation effect and an inter-reservoir storage capacity compensation effect, has stronger persuasion for the feasibility analysis of the connecting engineering, and facilitates guiding the management decision personnel to make the reasonable decisions about the reservoir connectivity problem.

Description

technical field [0001] The invention belongs to the technical field of reservoir dispatching operation, and in particular relates to a reservoir connectivity analysis method based on multi-objective analysis. Background technique [0002] In response to a series of water resource problems and challenges facing our country, the Ministry of Water Resources has proposed a river and lake water system connectivity strategy. , Adjustable river and lake water network system" to improve the level of water resource regulation and water supply security. In fact, there have been quite a few practical projects connecting rivers and lakes in China, such as the South-to-North Water Diversion Project and the East-to-West Water Diversion Project. major changes. Since the river-lake system connectivity strategy was put forward, the implementation of water diversion projects and the construction of river-lake connectivity systems have been accelerated in China. However, due to the lack of ...
