Evaluation system of substation green construction index based on AHP and entropy method

With the scale of China's electric power supply system increasing year by year, the consumption of renewable resources and the damage to the surrounding environment of electric power projects are increasing again. Therefore, in order to respond to the call of national green sustainable development, it is the future development trend to popularize green construction in electric power projects and combine green construction with electric power projects. Firstly, by consulting the relevant domestic and foreign literatures and the latest scientific research journals in the early stage, this paper sorts out the construction characteristics of substation projects in electric power engineering, the characteristics of green construction, the processes and links that are prone to excessive energy consumption and environmental pollution in the whole life cycle of substation projects, and summarizes a construction method of green construction index system of substation. Secondly, the objective weighting method of entropy is used to determine the index weight, and the subjective weighting method of AHP is used to determine the index weight respectively. Finally, in order to avoid the subjectivity or objectivity of the obtained weights affecting the authenticity of the data, an optimization function is introduced, and the two methods, namely entropy -AHP method, are combined and weighted to obtain a more reasonable weight distribution, and the fuzzy mathematics comprehensive evaluation method is used to analyze the results.
