Embodiment Construction

[0025] The technical solutions of the present invention will be further described below through the accompanying drawings and embodiments.

[0026] (1) First-level and second-level index weighting based on AHP

[0027] AHP empowerment process and steps are as follows in the present invention:

[0028] The first step: determine the sequence relationship, if a certain evaluation index x in the energy efficiency evaluation index system of industrial power users i The degree of importance relative to a certain evaluation criterion or goal is not inferior to x j , then record as x i > x j . If the evaluation index x 1 , x 2 ,...,x m Relative to a certain evaluation criterion or target has the relation x 1 > x 2 >… >x m , it is said that the corresponding order relationship is determined by ">" between the evaluation indicators. For the evaluation index set X={x 1 , x 2 ,...,x m}, the sequence relationship can be established according to the following steps: select t...

Abstract

The invention provides a method for evaluating electricity energy efficiency for an industrial user. The method comprises the following steps of establishing a three-level electricity energy efficiency evaluation index suitably for being used for an industrial user from technology, economy and management levels; determining the weight coefficients of the first level and second level indexes in the energy efficiency index by an analytic hierarchy process; determining the weight coefficient of the third level index in the energy efficiency index by an entropy method; and finally structuring a comprehensively weighted electricity energy efficiency evaluation model according to the weight coefficient of the third level index. The method provided by the invention can be used for overcoming the disadvantage of single weighting method, ensuring the scientificity and reliability of the evaluation model, and supplying guidance for the industrial user to develop the electricity energy efficiency diagnosis analysis, energy-saving potential analysis and energy-saving reformation.

Description

technical field [0001] The invention relates to a method for evaluating electric energy efficiency of industrial users, belonging to the fields of energy technology and electrical engineering. Background technique [0002] The energy consumption evaluation of industrial users, especially high-energy-consuming enterprises, is the focus of work to achieve energy-saving goals, and is the main source of demand and application carrier for the development and innovation of energy-saving technologies. At present, many enterprises do not have a set of scientific and reasonable energy efficiency evaluation systems and methods, and lack an accurate understanding of the specific use of energy and the benefits it generates, resulting in the loss and waste of energy in the production process and affecting the cost of products. Estimation and effective control of enterprise energy consumption. [0003] The progress of power energy efficiency testing and evaluation for industrial users is...
