Ecological dispatching method for reservoir based on ecological dispatching graph

Abstract

The invention relates to an ecological dispatching method for a reservoir based on an ecological dispatching graph, which comprises the following steps of: firstly, adding ecological water requirements into a water supply plan of the reservoir as a water supply department, calculating the utilizable capacity and the key dispatching line of the reservoir by using the diachronous method and the actual typical year method respectively, and further drawing the ecological dispatching graph of the reservoir; and then, formulating dispatching modes when the water level of the reservoir is in different areas including an area above the dead water level and below the limiting flood level, an area above the limiting flood level and below a lower dispatching line, an area above the lower dispatching line and below an upper dispatching line, an area above the upper dispatching line and below flood-fighting line, and the like, according to the ecological dispatching graph of the reservoir. The ecological water requirements are added into the traditional ecological dispatching graph, and the ecological dispatching graph is used for instructing the dispatching modes, therefore, the ecological dispatching of the reservoir is more practical and can be applied more easily.

Description

technical field [0001] The invention belongs to the field of environmental protection and relates to a reservoir ecological regulation method. In particular, it relates to a method for incorporating ecological water demand into conventional reservoir dispatching diagrams to realize reservoir ecological dispatching. Background technique [0002] The construction of water conservancy projects has not only brought huge economic and social benefits to human beings, but also greatly changed the original natural evolution and change process of the downstream rivers. Traditional water conservancy projects, whether they are designed, constructed or dispatched, are mainly aimed at promoting benefits and eliminating harm, focusing on the role of water conservancy projects in flood control, power generation, water supply, shipping, irrigation, etc., while ignoring the requirements of the ecological environment. It has caused a series of ecological and environmental problems such as ri...

Problems solved by technology

Some scholars proposed to assign certain weights to socio-economic goals and ecological goals respectively, and then add the two together to convert the multi-objective function into a single-objective function (patent "Optimization and determination method for water supply reservoir scheduling diagram taking into account human and ecological needs" , application number 200910265478.6), where the weights of socio-economic goals and ecological goals are different, representing the difference in the importance of the two in the decision-making process, but because the weights have no clear practical meaning and are highly subjective, they are not practical. The manager's decision-making in scheduling has caused certain difficulties

[0005] In addition, most of the research on ecological scheduling ignores the ecological scheduling method based on scheduling graphs.
