Classification of substation single-line diagrams based on fuzzy systems

This paper proposes three approaches to classify substation single-line diagrams so it can be used in a power distribution network expansion. With these approaches the expertise shall confront different single-line diagrams, so he can choose the best solution to a given problem. This classification is based on reliability, operational flexibility and impact on the environment criteria of each electrical equipment that is part of a substation specification. Simulations were accomplished to establish the best way to stand for the classification criteria through the fuzzy logic use and the approach with the best outcomes in the classification.
