摘　　要：在当前配网差动保护过程中,获取差动保护判据时仅能对单一参数进行处理,导致差动保护效果受故障位置影响较大,对此提出基于5G端到端网络切片技术的配网差动保护方法。根据“充分式”思想进行配网充分式故障识别与分析,选用5G端到端网络切片技术进行配网端到端网络切片处理,获取配网通信网络部分判据,采集复合式判据,设定差动保护启动单元,实现配网差动保护。仿真实验结果证实,无论故障点在保护区内或是保护区外,其使用效果均不会受到故障点位置的影响,保护装置可及时启动保护单元,维护配网运行的稳定性。In the current process of distribution network differential protection,only a single parameter can be processed when obtaining the differential protection criterion,resulting in the problem that the effect of differential protection is greatly affected by the fault location.Hence,a distribution network differential protection method based on 5G end-to-end network slicing technology is proposed.According to the“sufficiency”thinking,the sufficient fault identification and analysis of distribution network are carried out.The 5G end-to-end network slicing technology is selected to process the end-to-end network slicing of distribution network,obtain the partial criterion of distribution network communication network,collect the composite criterion,set the starting unit of differential protection,and realize the differential protection of distribution network.The simulation results show that whether the fault point is inside or outside the protection area,its use effect will not be affected by the location of the fault point.The protection unit can be started in time to maintain the stability of distribution network operation.
