摘　　要：借助光纤光栅(FBG)、相位敏感型光时域反射计(Φ-OTDR)及基于拉曼散射的分布式温度传感器(DTS),对4km长的高压输电真型线路的健康监测进行研究。分析了导线舞动过程中输电塔架和输电导线的温度和应变的特征。利用安装在塔架结构上的104个FBG应变和温度传感器对塔架结构进行应变监测。利用Φ-OTDR及DTS,借助输电线路中现有的光纤复合架空地线(OPGW)内的通信光纤,实现了输电线路的舞动和温度的监测。三种光纤传感方案相互补充照应,实现了对整个输电系统结构健康监测。Health monitoring of the high-voltage transmission line system with the length of 4 km is analyzed by means of fiber Bragg grating（FBG）,phase sensitive optical time-domain reflectometer（Φ-OTDR）and distributed temperature sensor（DTS）based on Raman scattering.The strain and temperature of the transmission tower and the transmission wire are focused on during the transmission line galloping.104 FBGs,working as strain and temperature sensors,are installed on one of the power towers.Based on the communication fibers in the optical fiber composite over-head ground wire（OPGW）,Φ-OTDR and DTS technologies are used to monitor the galloping of the transmission line.These three kinds of optical fiber sensing schemes are complementary to each other and the health monitoring of the power transmission system is realized.
