摘　　要：为提高光纤复合架空相线(Optical Phase Conductor,OPPC)在线实时监测系统性能,以OPPC应力应变和温度监测为研究对象,提出一种基于光纤传感器的OPPC在线实时监测方法。方法通过搭建布里渊光时域分析(Brillouin Optical Time-Domain Analysis,BOTDA)与布里渊光时域反射(Brillouin Optical Time Domain Reflectometer,BOTDR)系统,对OPPC进行应力应变和温度监测,实现了OPPC在线实时检测。仿真结果表明,相较于BOTDR系统,BOTDA系统对OPPC应力应变监测的测量有效距离更长、空间分辨率更高、测量精度更高,且更容易准确定位引下线,实现线路应力分析;对OPPC温度的监测效果更好,更能实时反映OPPC的温度运行状况,确保OPPC运行安全,为提高OPPC在线实时监测系统的性能提供了参考。In order to improve the performance of online real-time monitoring system of optical fiber composite overhead phase conductor(OPPC),an online real-time monitoring method of OPPC based on optical fiber sensor is proposed with the stress,strain and temperature monitoring of OPPC as the research object.Methods By building Brillouin Optical Time-Domain Analysis(BOTDA)and Brillouin Optical Time Domain Reflector(BOTDR)systems,the stress,strain and temperature of OPPC were monitored,and the online real-time detection of OPPC was realized.The simulation results show that compared with the BOTDR system,the BOTDA system has longer effective distance,higher spatial resolution and higher measurement accuracy for OPPC stress and strain monitoring,and it is easier to accurately locate the downlead to realize line stress analysis;The monitoring effect of OPPC temperature is better,which can reflect the temperature operation status of OPPC in real time,ensure the operation safety of OPPC,and provide a reference for improving the performance of OPPC online real-time monitoring system.
