Due to its tough demands of communication medium for the equivalent communication of intelligent distributed feeder automation (FA), it mainly adopts the optical fiber communication mode based on ethernet passive optical network (EPON) or industrial Ethernet technology. This communication mode requires the laying of expensive fiber optic cable channels, so it is difficult to apply in the old town or line transformation area. By studying the process of intelligent distributed FA fault management and the adaptability of intelligent distributed FA in the wireless communication situation, this paper puts forward an intelligent distributed FA technology based on 4G/5G wireless communication. The method of combining application-layer protocol control with fault handling process is adopted to realize the close cooperation between the communication time index and FA process among terminals. For abnormal situations such as communication interruption, communication delay and packet loss, communication multi-pack. It comples the distributed fault treatment under wireless communication. Through the simulation of the multi-scene test and application in Jinhua, Zhejiang province, it is shown that the proposed algorithm adapts to different conditions of wireless communication and accurately completes fault isolation and non-failure areas recovery. The effectiveness of intelligent distributed FA technology based on wireless communication is verified.
