Application of Entropy Fuzzy Matter Element Method to Ground-based Network of Corrosion Prediction

In order to make a more accurate evaluation on electric power grounding grid corrosion, predict the grounding grid service life and ensure the safe operation of power system, fuzzy matter element analysis method and entropy theory was used together to establish the prediction model of soil corrosion of substation. By identifying the main factors of soil corrosion evaluation and evaluation grade standard, an evaluation system was established, the weight of each index size was determined using the entropy weight method, the soil corrosiveness evaluation was realized, the grounding grid service life was preliminarily estimated. Combined with examples and comparison diagram, the effectiveness of the proposed method was verified, which can effectively fit the different dimensions and levels of data fully and reduce the subjectivity and experiential factors greatly, and eliminate the limitations of the Baeckman method, and thus make the evaluation results more reliable.
