In distribution network reconstruction, the multiple objective evaluation function model is established based on the system average interruption frequency index and the average service unavailability index which characterize the reliability of distribution network, and factors of the active power loss. The analytic hierarchy process is applied to the hierarchy analysis of the three factors. According to the definition of comparative scale, the judgment matrix is formed. Each goal weight is calculated, and a normalized target model is obtained, thus the comprehensive satisfaction evaluation function is formed. Based on intelligent PSO algorithm, the active power network loss is considered before the reconstruction, and the reliability factors are considered in the later period. IEEE69 node system simulation results verify the stability and the superiority of the algorithm.
