Principle and Implementation Method of Remote Standby Automation in Substation Based on 5G Communication Mode

为解决中低压电网光纤敷设成本高、远方备自投应用困难的问题,提出一种基于5G通信方式的变电站远方备自投原理及实现方法,通过在每个远方备自投中设置一台5G路由器,由路由器实现采用GRE TAP模式完成远方备自投的点对点通信,从而实现变电站远方备自投的信息交互。在RTDS中搭建仿真模型验证基于5G通信技术的远方备自投方案的可行性,该方法无需改变原有远方备自投的软硬件,避免了现有技术方案易受到地域限制而需要增加光纤通道的问题,使远方备自投装置更加方便、可靠,且结构简单、抗干扰能力强,极大地增加了在中低压电网应用的可能性。

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.
