摘要

5G网络为配电网各断路器保护装置之间的信息交互提供了通信平台。为解决配电网传统过流保护定值因整定失配造成的越级风险

文中提出一种基于5G通信的配电网区域保护方案，通过在成都配电网开展的实际应用，验证了该方案的可行性。首先，给出了配电网5G区域保护的架构；其次，分析了配电网5G区域保护的动作逻辑，该方案依据区域内断路器的过流及方向标志的组合信号进行故障定位；最后，给出了配电网5G区域保护的整定计算原则。

Abstract

5G network provides a communication platform for the information interaction between switch protection devices of distribution network. In order to solve the risk of leapfrogging caused by the setting mismatch of traditional overcurrent protection setting value of distribution network

a regional protection scheme for distribution network is proposed based on 5G communication

and through the actual application carried out in Chengdu distribution network

the feasibility of the proposed scheme is verified. Firstly

the architecture of 5G regional protection in distribution network is given. Secondly

the action logic of 5G regional protection in distribution network is analyzed

and the fault is located based on the combined signals of overcurrent and direction signs of the switches in the area. Finally

the setting calculation principle of 5G regional protection in distribution network is given.
