Reservoir water supply scheme determination method and device

Abstract

The embodiment of the invention provides a reservoir water supply scheme determination method and device, and the method comprises the steps: determining a water level preference coefficient corresponding to each water intake control station based on a water level simulation model of the relation between the reservoir-out water flow of a reservoir-out section of a target reservoir and the water level of each water intake control station; according to the water level preference coefficient corresponding to each water intake control station and the drought demand preference coefficient corresponding to each water intake area, determining a water supply benefit function corresponding to each downstream water intake control station, and taking the power generation benefit function and the water supply benefit function of the target reservoir as target functions of a water supply scheduling model; and according to a preset constraint condition, constructing a water supply scheduling model of the target reservoir, and inputting the plurality of water supply scheduling schemes of the target reservoir into the water supply scheduling model to obtain a target water supply scheduling scheme. According to the invention, bidirectional feedback of the reservoir scheduling scheme and the water taking and using of the downstream area is realized, so that the target water supply scheduling scheme is more scientific and reasonable.

Description

technical field [0001] The present application relates to the technical field of smart cities, and in particular to a method and device for determining a water supply scheme of a reservoir. Background technique [0002] Water abstraction from natural river channels is one of the key sources of water abstraction for important provinces and cities located along the river / river. Reservoir outflow decisions in the upstream will have a certain impact on the water intake from the river by the important downstream provinces and cities. Therefore, it is necessary to comprehensively consider the water demand of the important downstream provinces and cities to draw water from the river, and make a rational decision on the optimal scheduling of reservoir water supply. [0003] The traditional reservoir water supply optimization scheduling decision is made according to the water intake demand of the corresponding water intake area. It is necessary to ensure that the water level of the ...

Problems solved by technology

[0003] The traditional reservoir water supply optimization scheduling decision is made according to the water intake demand of the corresponding water intake area. It is necessary to ensure that the water level of the water intake control station corresponding to the water intake area reaches a fixed design value. If the water level of the water intake control station reaches the design value, the representation can be guaranteed Corresponding to the water intake needs of provinces and cities, but the actual occurrence of drought events in different water intake areas, the historical period and the scope of influence are all different

In addition, the reservoir water supply scheduling strategy is generally to ensure the flow decision of the reservoir outlet section, and flow along the river channel from top to bottom to the water intake control stations of various provinces and cities. Differences in water quality and drought conditions in various provinces and cities have not been fed back to the outlet section of the reservoir from bottom to top, that is, the decision-making of reservoir water supply dispatching is one-way

To sum up, the water supply scheduling decision made by the traditional method has certain flaws, which is not scientific and reasonable enough.
