Abstract

Differential protection of distribution network has high communication requirements for reliability, time delay and delay jitter. Theoretically 5G can meet these requirements. However, real network test results show that there are problems such as burst large delay and burst packet loss for differential protection based on the current 5G network, and deterministic capability of the current network is poor. This paper first gives the real network test results of differential protection based on 5G, and then gives a general description of deterministic technologies and the possible solution to meet the requirements of differential protection.
