It is of great significance to improve the capability of real-time monitoring and fault location for ensuring the normal operation of power distribution network.In this paper,an improved ant colony algorithm is used to locate distribution network faults.Based on the structural characteristics of distribution network,pheromone initialization and dynamic pheromone updating strategies are designed to improve the convergence speed and location accuracy of the algorithm.The simulation results show that the improved ant colony algorithm has good accuracy and better convergence speed than the traditional ant colony algorithm.
