Distribution network fault diagnosis technology based on intelligent algorithm

Fast and accurate fault diagnosis of distribution network is the key to ensure the reliability and security of power supply in distribution network. For distribution network fault diagnosis technology at home and abroad at present, mainly around the fault section location and precise ranging from two aspects, this paper combined with the latest research results of distribution network fault diagnosis technology, summarizes the related technologies of section positioning and fault location method, including matrix algorithm, genetic algorithm (GA), neural network algorithm (NNA), particle swarm optimization (PSO) algorithm, traveling wave method, impedance method, fault wave record device intelligent algorithm, etc., analyzes the basic principle and advantages and disadvantages of each algorithm, finally, the future development of the fault diagnosis technology is prospected.
