To enhance the safety monitoring of power transmission lines, the distributed fiber Bragg grating array sensing technology was employed to measure the dynamic motion characteristics of optical power ground wire (OPGW) cables in laboratory conditions. The results show that this technology can effectively monitor the dynamic behavior of OPGW under simulated aeolian vibrations and galloping states, clearly recording various vibration patterns. The experimental data reveal that by increasing the spatial density of the grating array sensors and reducing the system's low-frequency phase drift, the monitoring performance can be further enhanced. It is evident that the distributed vibration sensing technology based on fiber Bragg grating arrays provides a novel technical approach for the distributed dynamic structural health monitoring of OPGW cables.

为提高输电线路安全监测水平,通过分布式光纤光栅阵列传感技术,对光纤复合架空地线光缆(optical power ground wire,OPGW)的动态运动特性进行实验室测量。结果表明:该技术能有效监测OPGW在模拟微风振动和舞动状态下的动态行为,清晰记录不同振动模式。实验数据揭示,通过提高光栅阵列传感器的空间密度和降低系统低频相位漂移,可进一步提升监测性能。可见,基于光纤布拉格光栅阵列的分布式振动传感技术为OPGW电缆的分布式动态结构健康监测提供了新的技术手段。
