关于500kV线路光纤纵联保护的运维研究

Dimension of Transport on 500kV Line of Fiber Pilot Protection

500k V电网是骨干网架,其主保护为光纤纵联保护,做好该类保护的运维工作的意义十分重大。文章首先介绍了光纤纵联保护的原理和通道介质,其次论述了保证线路两端保护逻辑协同的时钟设置、纵联码标定等内容,接着重点分析了光纤纵联保护的故障排除方法、日常运维要点、各运维专业的分工界面以及提升光纤纵联保护"综合生存能力"的针对性措施,最后本文就运维工作中如何高效进行光纤纵联保护的定检进行了适当探析。

500kV grid is the backbone network, the main protection for the optical fiber pilot protection, operation and maintenance of such good sense to protect very important work. The article first introduces the Fiber Pilot Protection Principle and channel medium, followed by discussion of the guarantee line ends synergistic protection logic clock setting, longitudinal code calibration, etc., and then analyzes the fiber pilot protection troubleshooting methods, daily operation dimensional points, operation and maintenance of each professional division interface and enhance fiber pilot protection ＂comprehensive viability＂ of the specific measures, the final article on the operation and maintenance work carried out on how effective a given fiber pilot protection were properly seized of.
