摘要
介绍了西安地区保护信号的传输现状,重点对利用SDH自愈环传输保护信号进行了探讨,对保护信号传输的各种方式进行了分析,结合实际提出了西安地区光纤保护的使用方案,提出继电保护可以使用SDH光纤通道的结论。
The current transmission state of electric power protection signal in Xi′an is introduced in this paper,and utilizing self-healing ring of SDH to transmit electric power protection signal is especially discussed. After various transmission manners of protection signal are analyzed,and combined with the present state of Xi′an optical fiber network,the scheme of using self-healing ring of SDH to transmit electric power protection signal is brought forward.
