摘　　要：智能配网差动保护数据传输可能会产生大量流量,造成利用5G切片技术进行通信时的时延增加。文章在阐述5G智能配网差动保护技术原理的基础上,讨论了增加保护联跳继电器以解决两侧差动保护动作行为不一致引起的双向通信不对称的问题,从资源配置、通信协议、传输机制、优化算法、传输方式等方面比较分析了5G流量控制方法,说明采用矢量差动算法和非标准可路由SV(routed-sampled value,R-SV)协议能够有效减少5G通信产生的流量,满足智能配网差动保护的时延要求,而5G与光纤通道结合方式在差动保护的实际应用中可靠性更高。Smart distribution network differential protection data transmission may generate a large amount of traffic,resulting in increased latency when communicating using 5G slicing technology.In this paper,on the basis of elaborating the principle of 5G smart distribution network differential protection technology,we discuss increasing the protection joint-trip relay to solve the problem of asymmetric bidirectional communication caused by the inconsistent action of the differential protection on both sides,and then we compare and analyze the 5G traffic control methods in terms of resource allocation,communication protocols,transmission mechanisms,optimization algorithms,and transmission modes to illustrate that the adoption of the vectorial differential algorithm and the non-standard R-SV protocol can effectively reduce the traffic generated by 5G communication and meet the delay requirements of smart distribution network differential protection,while the combination of 5G and fiber optics channel method is more reliable in the practical application of differential protection.
