Based on the characteristics of distribution network, the computational approach of network loss for distribution network is put forward, the mathematic model of network reconstruction whose function is to minimize the effective network loss is set up and voltage restriction and volume restriction are defined, and the method which seek secondary optimal value is analyzed. Using simulated annealing calculation method, the steps of optimal composition of distribution network swithing state are determined. This method is applicable to distribution network with varied votage grades and volume. The active eocnomic runing of distribution network is realized.
