Firstly, according to the main function of distri- bution network self-healing system and requirements of distribution network supply, the paper expounds the distribution network self-healing control system performance evaluation. Based on this evaluation, the paper builds distribution network self-healing objective function and its constraints related param- eters which calculate the maximum fitness value for the calculation of the target. Then it introduces working principle of parti- cle swarm optimization（PSO）. And details implementation steps of improved particle swarm optimization algorithm. Finally, combines distribution network self-healing objective function and improved particle swarm algorithm, put forwards control method of distribution network self-healing which based on PSO, and introduces its working principle and realization flow chart. The simulation results show that method of distribution network self-healing control in this paper has better convergence.
