Research on the comprehensive evaluation index system of distribution network reliability

The present study, firstly, puts forth a comprehensive and reasonable reliability assessing theory system directing at fuzzy layers and the incomprehensive factors of current distribution network. Next, the four major characteristics influencing reliability of the distribution system have been defined and research has been conducted on grade one and grade two as well as basic index involving those four aspects. Then, on those bases, this study constructs scoring standard of the basic indexes and determines the weighting relation in the same lay index, with the combination of the Analytic Hierarchy Process (AHP), the comprehensive evaluation index system of distribution network reliability which closely related to actual situation has been put forward. Finally, the validity and practicability of the current method is verified by the analysis and evaluation of some distribution network´s reliability.
