Research of Fiber Optie Sensing Technology and Its Application to Online Landslide Monitoring of Transmission Line Corrider

摘要:

为提升电网对地质灾害的监测及防护水平，对基于光学传感技术的输电走廊滑坡在线监测方法进行了研究， 并在某500 kV 输电线路313 号和314 号塔进行了现场应用。根据大量现场勘察数据，针对性地制定了科学有效的监 测方案，搭建了一套基于光纤传感网络的在线监测平台，并且分析了降雨量、倾斜角和表面裂缝与滑坡体状态的关 联; 最后依据获取的监测数据对某500 kV 输电线路313 号和314 号塔进行了诊断，诊断结果表明其具有较高的实时 性和准确性。

Abstract:

In order to improve the monitoring and protection level of geological disasters in power grid，online landslide monitoring method is studied for transmission line corridor based on fiber optic sensing technology，and the research results is applied to No． 313 and No． 314 tower of a 500 kV transmission line． According to plenty of site survey data，a scientific monitoring program is developed，an online monitoring system is set up and the relationship between rainfall，tilt angle，crack and landslide status is analyzed． At last，No． 313 and No． 314 tower of a 500 kV transmission line are diagnosed according to the monitoring data，and the results show that the system is more timely and accurately．
