Substation Project Evaluation Model Based on Coefficient of Variation And Fuzzy Comprehensive Evaluation

Aiming at the problems of single traditional index, fuzzy evaluation result and subjective index weight in evaluating the investment benefit of substation project, a substation project evaluation model based on coefficient of variation and fuzzy comprehensive evaluation is constructed. First of all, this paper constructs a more perfect evaluation substation project investment index system from four dimensions: project maturity, project rationality, project effectiveness and investment construction environment. Furthermore, a combination weighting method based on coefficient of variation is proposed and introduced into the calculation of fuzzy comprehensive score, and the necessity model of power grid project investment is established. Finally, an example analysis is carried out for the 35kv project put into production in a certain province, and it is verified that the weighting method and evaluation model proposed in this paper can reasonably and effectively quantify the investment benefit and necessity of the evaluated substation project, which is practical in promoting the lean investment of the substation project.
