Construction and Application of Distribution Automation System in Island Based on "Beidou-5G-Quantum" Secure Communication

This article put forward a new construction and application mode of new generation distribution automation system in island based on "beidou-5G-quantum" secure communication, in view of the fact that the existing secure communication mode is difficult to meet the requirements of the real-time, reliability, security and low delay. A variety of secure communication technologies such as "beidou short message", "5G hard slice" and "quantum encryption" are used to improve communication security protection and overall control ability of distribution network, break through traditional communication bottleneck. It is suitable for practical application of complex distribution network engineering, effectively solve the problems of distribution network cable laying difficulty and high investment cost and communication problems in remote, unsignaled, isolated areas. It can be used as a powerful supplement for optical fiber and public network of traditional communication methods in construction of island distribution network.
