摘　　要：5G技术可为配网差动保护技术应用提供通信解决方案,但5G网络的时延和抖动依然不稳定,影响配网差动保护的正常工作。目前5G配网差动保护应用缺乏对端到端通信链路性能实时、精确监测的手段。文章提出一种在5G终端中对差动保护的特定报文标记时间信息进行网络性能监测的探针技术,并分别基于5G虚拟专网软切片和硬切片的组网方案,验证网络探针技术在差动保护业务中的应用可行性,为5G技术在电力业务中的广泛应用提供保障。5G technology can provide communication solutions for distribution network differential protection technology applications,but the latency and jitter of 5G networks are still unstable,which affects the normal work of distribution network differential protection.Currently,5G distribution network differential protection applications lack the means to monitor the performance of end-to-end communication links in real time and accurately.This paper proposes a probe technology for network performance monitoring of specific message tagging time information for differential protection in 5G terminals,and verifies the feasibility of applying network probe technology in differential protection business based on the networking scheme of soft slicing and hard slicing of 5G virtual private network,respectively,to provide a guarantee for the wide application of 5G technology in power business.
