摘要
针对配电网差动保护数据传输存在延时等问题,采用5G通信技术独立组网,提供高可靠、低延时通信链路,能够增强数据传递实时性,增强差动保护动作可靠性.文章在搭建5G差动保护通信架构的基础上,从数据同步和报文传输两个方面对配电网差动保护5G通信关键技术展开分析,在方案实现阶段发现差动保护动作时间受通信时延影响,通过采用外部时钟实现采样同步,能够使差动保护性能达到配电网运行要求.
Abstract
In view of the delay of differential protection data transmission in distribution network,5G communication technology is used for independent networking to provide highly reliable and low-delay communication links,which can enhance the real-time performance of data transmission and enhance the reliability of differential protection action.Based on the construction of 5G differential protection communication architecture,the key technologies of 5G differential protection communication in distribution network are analyzed from two aspects:data synchronization and message transmission.In the implementation phase,it is found that the action time of differential protection will be affected by communication delay.By using external clock to realize sampling synchronization,the differential protection performance can meet the operation requirements of distribution network.
