继电保护光纤复用技术应用探究

Research and Application of New Plant Network Power Communication Technology

本文介绍了某电厂线路加强工程规划建设中所面临的通信问题,并结合云南电网全面数字化转型和数字电网建设战略,提出了一种复用保护通道及新技术的应用方法。通过采用新型通信设备,并推行新型光接口标准,实现继电保护装置和SDH光传输设备以光纤的形式直接连接。这种方式的传输模式具有节省机房空间,简化电网业务信号编解码、解决传统通道保护业务不能远程网管监控等优点,打破原有技术壁垒,提高通道可靠性及设备兼容性,推进了设备国产化,节约了投资,并适用于各类应用场景。

This paper introduces the communication problems faced in the planning and construction of a power plant line strengthening project,and combined with the comprehensive digital transformation of Yunnan power grid and digital power grid construction strategy,puts forward an application method of multiplex protection channel and new technology.Through the adoption of new communication equipment and the implementation of new optical interface standards,the relay protection device and SDH optical transmission equipment are directly connected in the form of opticalfiber.This mode of transmission has the advantages of saving room space,simplifying power grid service signal codec,solving the traditional channel protection service can not be remote network monitoring,breaking the original technical barriers,improving channel reliability and equipment compatibility,promoting the localization of equipment,saving investment,and suitable for various application scenarios.
