The Research of Grounding Grid Corrosion Factors Based on Vector Similarity and Fuzzy Techniques

In this paper, a structure combined vector similarity and fuzzy techniques was present to establish the grounding grid corrosion research model. Set corrosion factors of each sample as the feature vectors and make dimensionless, by calculating the similarity of feature vectors and corrosion rate vectors, the weight of each corrosion factor on corrosion rate was obtained, combine closeness principles of fuzzy technology to predict corrosion rate. Example prove, using vector similarity method can accurately determine the weight of each corrosion factor affecting the corrosion rate, and corrosion prediction model combined with fuzzy technology and closeness principle can predict corrosion rate effectively and stably.
