The invention, which belongs to the technical field of distribution automation, especially relates to a feeder automation system. The intelligent distributed feeder automation system comprises a plurality of feeder automation terminals; and the adjacent feeder automation terminals carry out information exchange by information exchanger passages. Each feeder automation terminal includes a starting module, a positioning module, and a fault isolation module; the starting module starts the feeder automation terminal under a predetermined information effect; the positioning module is used for detecting switching of the feeder automation terminal and adjacent switching fault information in the information exchange and then determining fault location; and the fault isolation module connected with the positioning module is used for executing fault area isolation based on the fault location. On the basis of the technical scheme, the topological analysis module has high integrity and the topological tracking and analysis of the whole feeder automation terminal system can be realized conveniently; the topological structural change of the feeder automation terminal does not affect adjacent feeder automation terminal configuration, so that the maintenance becomes simple and convenient; and equipment replacement of different manufacturers can be carried out under the circumstance that the adjacent feeder automation terminal configuration is not changed.
