| 摘 要： | 差动保护具有良好的可靠性、选择性和速动性，但受制于保护通道的建设，差动保护在配电网中仍未被广泛使用。本文介绍了1种基于5G技术的配网差动保护，利用5G技术实现差动保护数据交互，有效解决了配网差动保护通道建设难题。现场测试表明，差动保护可依托5G网络实现信息交互，但交互时延不稳定是制约实际应用的关键问题。

| Abstract: | Differential protection has good reliability, selectivity and quick action, but subject to the construction of protection channels, differential protection has not been widely used in distribution networks.This article introduces a 5G technology-based differential protection for distribution networks.The 5G technology is used to implement differential protection data interaction, which effectively solves the problem of differential protection channel construction in distribution networks.Field tests show that the differential protection can realize information exchange based on 5G network,and the instability of interaction delay is the key problem restricting the practical application. |
