分散式DTU终端通信技术研究与应用

Research and Application of Distributed DTU Terminal Communication Technology

随着配电自动化技术的不断发展,国内10 kV配电终端的设计模式逐步转向分散式DTU终端。然而在现有配网自动化系统架构下,尚无很好的方案能实现分散式DTU终端整体数据上送配电主站。提出了通过分散式DTU终端公共单元与配电主站之间建立多个端口服务的模式来实现配电主站与分散式DTU终端整体进行通信的需求,有效地解决了分散式DTU终端与配电主站三遥、定值以及文件等数据交互问题。

With the continuous development of distribution automation technology,the design mode of 10 kV distribution terminal in China has gradually shifted to distributed DTU terminal.However,under the existing distribution network automation system architecture,there is still no good scheme to realize the overall data of distributed DTU terminal transmitted to the distribution master station.This paper proposes the method of establishing a multi-port service mode between distributed DTU common unit and master station so as to realize the demand of communication between master station and distributed DTU terminals,which effectively solves the problems of data interaction concerning"three remote"systems,fixed value,files,etc.between distributed DTU terminal and distribution master station.
