Abstract:: The mathematical model of distribution network reconfiguration which contains distributed generators is established.The research of hybrid particle swarm optimal algorithm ，which has been used to deliberate the reconfiguration problem，is mainly focused in this paper.For low computational efficiency and poor stability of particle swarm algorithm ，three heuristic principles are established to ameliorate the efficiency and the stability of the algorithm.Using IEEE 33 node distribution system as the object ，the model and the algorithm was validated.It turned out that the refined hybrid particle swarm optimal algorithm can work with the problem of distribution network reconfiguration which contains distributed generators more efficient and more stable.
