Ant Colony Algorithm for Solving Fault Location in Distribution Networks

As no ideal algorithms are currently available to solve the problem of fault location in distribution networks due to the aberration of fault over-current information, by making full use of the radiation-like characteristic of the distribution network and adopting the stage treatment, the entire distribution network is divided into a main branch and a number of independent regions, reducing the dimensions of feasible solutions and greatly improving the speed of fault location. The good plus feedback and high fault-tolerance performance of the ant colony algorithm is then used to search for local and global solutions. The effectiveness of the algorithm proposed is verified by simulation results.
