基于光纤数字通信的直流双边联跳保护方案

DC Two Mutual Transfer Tripping Protection Design Based on Optical Fiber Digital Communication

介绍北京地铁亦庄线在国内轨道交通工程中首次应用的基于光纤数字通信的直流双边联跳保护方案。阐述方案的回路构成、联跳动作原理,分析方案设计过程中需要重点考虑的环节,并提出具体要求。与传统电缆传输信号的直流双边联跳方案进行综合经济技术比较,表明新方案具有良好的抗干扰性能、数据传输可靠性高,可以适用于任何工程环境。

The Yizhuang line of Beijing metro project firstly in domestic rail transit applied DC two mutual transfer tripping protection based on optical fiber digital communication.This article introduces in detail the theory and composition of DC two mutual transfer tripping protection design and analyzes the key links to be considered in the design process and puts forward specific requirements.Compared in both economic and technical aspects with the traditional two mutual transfer tripping protection schemes based on cable transmission signal,the new project has good anti-disturbance performance and high reliability of data transmission,and it can be used in any engineering environment.
