Research and Application of Intelligent Distributed Distribution Protection Technology Based on 5GCommunication

The improvement of distribution network power supply reliability depends on perfect relay protection technology.This paper introduces a fast fault isolation technology of distribution network based on 5G wireless communication.By using the characteristics of 5G communication with large bandwidth,high reliability and low delay,it breaks through the limitations of optical fiber communication on the traditional fault isolation technology of traditional distribution network,and provides a new direction for the application of intelligent distributed distribution protection technology in more occasions.In order to solve the problem that conventional GOOSE messages cannot be transmitted in 5G networks,a method of applying R-GOOSE protocol to intelligent distributed distribution protection is proposed,and the problems of 5G bandwidth and traffic under this method are discussed.Finally,the pilot project application was used to verify the communication performance and protection functions,proving the effectiveness and applicability of the overall scheme.
