Abstract: The use of traditional artificial intelligence algorithm in distribution network feeder fault location is wide. But some shortcomings such as large initial population, too much iterations and falling into optimum exist. This paper puts forward the estimation of distribution algorithm to realize the fault location, in which the fault section vector is regarded as the right solution. By sampling from the individual probability model established in the solution space, the probability of the optimal fault section vector is gradually improved. The simulation result shows that the application of estimation of distribution algorithm in the fault section location in multiple source ring-open distribution network has faster speed and good fault tolerance.
