摘要
光纤纵联保护通道是实现继电保护系统高可靠性的关键。文章分析光纤通道时延、误码特性、人为造成的通道倒换方式选择错误、2 M通道重定时参数设置不当等问题,研究这些问题给保护系统带来的负面影响,提出了光纤保护对通道的要求及注意事项。
The longitudinal differential protection for optical fiber channel is very important for the reliability of relay protection system. This article analyzes the problems, such as the time delay and error code characteristic of optic fiber channel, path switching mistake caused by maintenance staff and improper parameter setting on 2 M channel retiming, which will produce negative influence on protection system. Some requirements and attention problems for channel are also put forward in the paper.
