Network reconfiguration is one of the most important measures to improve the economical operation, security and reliability of distribution networks. A fast service restoration method for distribution network is proposed in this paper by combining the heuristic rules with network reconfiguration theory. Breadth first traversal is utilized to find the outofservice area first. Subsequently, heuristic rules are employed to determine the service restoration strategy, whose aims at connecting the outofservice area to the energized area. For the network without the intending islanding part, a network reconfiguration model, whose objective is minimization of the network loss and constraints are the safety operation of the distribution network, is constructed for the rest network, and the improved harmony search algorithm is used to solve the model. The simulation results of 69 bus system show that the proposed method is superior to other methods, and the effectiveness of the proposed network reconfiguration model is verified.
