Comprehensive Evaluation of Social Benefits of Power Transmission and Transformation Projects Based on Entropy Method Optimization

Abstract

Power transmission and transformation projects, as Infrastructure construction projects, the scientific nature of their investments and the significance of investment benefits have been paid more and more attention to. At present, there are relatively few researches on social benefits evaluation index system of power transmission and transformation projects, and there is a lack of practical application of evaluating methods. With the goal of scientifically evaluating the social benefits of power transmission and transformation project, this paper extracts the social benefit evaluation indicators in the relevant domestic and foreign literature research, innovatively adopts the Entropy Method, and quantifies the relative importance of the indicators. After that, screens the original indicators and constructs the framework of conventional indexes and special indexes, then comprehensively forms a targeted evaluation index system. On this basis, uses Analytic Hierarchy Process to do the weight calculating and testing, and uses Fuzzy Comprehensive Evaluation Method to comprehensively analyze and evaluate the social benefits of power transmission and transformation projects. Then taking four large-scale power transmission and transformation projects in Henan as examples to comprehensively evaluate their social benefits, verify the feasibility and effectiveness of the method, and clarify the positive social benefits of power transmission and transformation projects.
