500kV北增乙线光纤保护通道联调方法

The Mutual Debugging of 500kV Beizeng CircuitⅡ Optical Protection Channel

光纤保护的使用日益广泛,光纤保护在通道联调时出现的问题也随之增加,经常会因联调前的准备工作不足而得不到迅速解决,影响联调进度,影响线路稳定运行。这里以500kV北郊变电站北增乙线光纤保护为实例,介绍光纤保护通道联调的步骤和方法。

Optical protection are being widely used increasingly, but owing to shortage of preparation work problem happens always in mutual debugging the optical channel. This will slower the mutual debugging and influence the operation of power transmission. Here with the optical protection of 500kV Beizeng Circuit Ⅱ in Beijiao substation as an example, the method and working procedure of optical protection channel mutual debugging is introduced.
