Method for optimizing normal storage water level of hydropower station

Abstract

The invention discloses a method for optimizing a normal storage water level of a hydropower station, which comprises the following steps of: 1, establishing a complete index system and classifying indexes in the index system; 2, raising a normal storage water level value, calculating a data establishment alternative scheme of the indexes under the water level value by using the mathematical integral operation, and repeating the step 2 to obtain an alternative scheme set; 3, calculating an index weight by using a discrete mathematics weighting method; 4, combining the alternative schemes in the alternative scheme set with a data matrix of the data establishment alternative schemes and carrying out dimensionless and standardization processing on the data matrix of the alternative schemes; 5, selecting a reference scheme from the processed data matrix of the alternative schemes, wherein the reference scheme consists of data with the highest value in index data; 6, calculating the degree of association between the alternative schemes in the alternative scheme set and the reference scheme; and 7, according to the size of the degree of association, sorting the alternative schemes and using the alternative scheme with the highest degree of association as the optimal scheme in the alternative schemes. The method disclosed by the invention has important practical application value in the field of hydraulic and hydro-power engineering and has wide application prospect.

Description

technical field [0001] The invention relates to the information technology field of hydropower project construction in GIS technology and multi-attribute decision-making method, and particularly relates to a method for optimizing the normal water storage level of a hydropower station. It is also applicable to the water level selection of other non-hydropower station projects. Background technique [0002] At present, my country's hydropower industry is in a period of rapid development, and the construction of hydropower projects has become the focus of my country's energy development strategy. Give priority to the development of hydropower projects and rationally adjust the national energy structure. To develop hydropower projects, it is necessary to continuously improve the technical level of engineering construction, continuously strengthen the research on technical methods of hydropower projects, improve the efficiency of hydropower project construction and reduce constr...

Problems solved by technology

However, the application of GIS technology in the hydropower industry is relatively scattered and has not formed a systematic application

It is widely used in surveying and mapping in the construction of hydropower projects, but less in the selection of normal water storage levels, so that the acquisition of inundation data still adopts the traditional method of manual survey and surveying and mapping personnel's field measurement or map calculation, which takes a lot of time , human and material resources
