Research of the Redundancy Technologies in the Communication Network for Distribution Automation

Abstract

As the demand of the power supply reliability is improved in recent years, the communication reliability for distribution automation system should be promoted. Redundancy technologies in the communication network can switch the interrupted communication channel to the normal communication channel to improve the communication reliability. This paper discusses several redundancy technologies in the communication network for distribution automation which includes the wireless communication technologies and wired communication technologies, and gives an application suggestion of these redundancy technologies in different application scenarios. The redundancy technologies this paper discussed can effectively improve the communication reliability of the communication network for distribution automation in the key power supply areas.
