Communication Technology Research and Application of Distributed DTU Terminal

As distribution automation technology develops, the design mode of domestic 10kV distribution terminals gradually turns to distributed distribution terminal unit(DTU) terminals. Howerver, there is not a good way to send the whole datas of a distributed DTU terminal to the master station under the existing distribution automation system architecture. This paper proposes the mode of multi-ports service between distributed DTU common unit and master station so as to realize the demand of communication between master station and distributed DTU terminals. It effectively solves the problem of data interaction which includes three-remote datas, settings and file transfers between distributed DTU terminals and master station.
