Design of Beidou Communication Module for Distribution Automation Feeder Terminal

With the continuous expansion of power distribution networks and the innovative development of communication technologies, most distribution networks adopt 4G communication technology for the intelligent management of feeder terminal units(FTU). However, in remote areas without network coverage, 4G communication methods are ineffective, rendering some FTU terminals unable to be remotely monitored and necessitating manual inspections for maintenance. This paper proposes a communication solution for distribution network feeder terminals that integrates the Beidou short message communication technology. By combining Beidou short message technology with existing communication methods and miniaturizing and integrating it into a communication module, the solution enables direct plug-and-play functionality and autonomous channel switching. This provides a stable and reliable communication method for FTU terminals. The effectiveness of this communication module solution is validated through experiments.
