The existing urban distribution network, especially in load-intensive areas, has a large number of 10 kV switching stations. However, the existing distribution network system lacks the effective supervision ability for 10 kV switching station equipment, and this seriously hinders the construction of a resilient urban distribution network. Therefore this paper proposes an intelligent transmission technology scheme for the fault information of a ductile distribution network based on 5G and IEC61850. In this scheme, the network changes in the sensing switch station are automatically identified by the automatic discovery and identification technology of protection equipment based on situational awareness. The protection device is automatically discovered and configured by the automatic configuration and access technology of secondary equipment based on IEC61850 communication. The information conversion and sharing between the master and slave stations of the power grid protection fault information are quickly and accurately realized by the configuration-free conversion technology from the object-oriented stereo data model based on IEC61850 to the flat data model. High-speed, real-time and reliable transmission of information is realized by the technology based on the 5G network. A system test environment is built to test the technical scheme and run it at the test station. The results show that the technical scheme can obtain real-time operational status in a timely fashion and important action information of the equipment on demand, and realize the effective supervision of 10 kV switching stations.
