Adaptability Evaluation Method of Distribution Terminal Based on AHP and CRITIC

Because the performance of distribution terminal is closely related to the reliability and automation level of distribution automation system, this paper proposes a method of distribution terminal adaptability evaluation based on the combination of the analytic hierarchy process and objective weight weighting method. By analyzing the working condition characteristics of the operation data collection and regulation control of distribution equipment, a two-level decision-making index system suitable for the selection of distribution terminal is constructed. Based on expert experience and technical requirements, the analytic hierarchy process is used to determine the weight of the first level of indicators. Considering the variability of indicators and the conflict between indicators, the objective weight weighting method is used to determine the weight of the second level of decision-making indicators. By synthesizing the weights of the two-level decision-making indexes, the comprehensive scoring of various types of distribution terminals are given. The effectiveness of this method is verified by an engineering example. This method provides a theoretical basis for the selection of distribution terminal in distribution automation systems, and has a certain engineering application value.
