Abstract

Abstract: In order to solve the problems of high cost of optical fiber laying in medium and low voltage power grid and difficult application of remote backup automatic switching, this paper provides a principle and implementation method of remote backup automatic switching in substation based on 5G communication mode. By setting a 5G router in each remote backup automatic switching, the router realizes the point-to-point communication of remote backup automatic switching in GRE TAP mode, so as to realize the information exchange of remote backup automatic switching in substation. The simulation model built in RTDS proves the feasibility of the proposed remote backup automatic switching scheme based on 5G communication technology. This method does not need to change the original hardware and software of the remote standby self-switching device, and avoids the need of adding optical fiber channel and so on, which makes the remote standby self-switching device more convenient and reliable.The structure is simple, and anti-interference ability is strong, which greatly increases in the low-voltage power network application possibility.

Key words: remote standby automatic switching, 5G network, GRE communication mode, medium and low voltage power grid, power supply reliability
