摘要
智能电网建设过程中工程配置复杂、主站与配电终端之间的人工信息校核工作量大等问题成为影响配电网发展的主要因素。基于IEC 61850标准建立了配电终端的自描述信息模型,分析了消息队列遥测传输协议(message queue telemetry transmission,MQTT)应用于即插即用技术的适用性,设计了基于MQTT协议的配电网通信架构,提出了基于MQTT协议的配电终端即插即用技术。以多台分布式配电终端(distribution terminal unit,DTU)与配电自动化云主站的即插即用为例,搭建了实际试验环境。试验结果表明,设计的通信架构及即插即用技术提高了数据传输效率,实现了配电终端即插即用的技术需求。
In the process of smart grid construction,complex engineering configuration and large workload of manual information check between the main station and the distribution terminals have become the main factors affecting the development of distribution network.Based on the IEC 61850 standard,the self-describing information model of the power distribution terminals was established,and the applicability of the message queue telemetry transmission(MQTT)to plug-and-play technology was analyzed,and the distribution network communication architecture based on the MQTT protocol was designed.The plug-and-play technology of power distribution terminal based on MQTT protocol was proposed.Taking the plug-and-play of multiple distributed distribution terminal units(DTU)and the distribution automation cloud master station as an example,the actual test environment was set up.The experimental results show that the communication architecture and plug-and-play technology designed improve the efficiency of data transmission and fulfill the technical requirements for plug-and-play power distribution terminals.
