摘　　要：提出了一种基于光纤Bragg光栅(FBG)传感器的架空输电线路覆冰厚度监测方案,并进行了仿真分析和实验验证。利用覆冰后输电线路的形变牵引FBG应变传感器,综合考虑FBG的应变量、实时气候条件等多种因素,得出输电线路的覆冰厚度。实验结果表明,方案能监测到30 mm覆冰厚度,测量精度和灵敏度达到1 mm覆冰厚度,有效监测距离可达40 km。仿真分析及实验测试结果一致,表明方案可有效测量长距离输电线路的覆冰厚度。An ice monitoring scheme for overhead power transmission lines with fiber Bragg grating（FBG） strain sensor is proposed,and simulation analysis and experimental validation sensor.FBG strain are performed was dragged by the deformation of iced overhead power transmission line.Based on an overall consideration of the strain of FBG,real time weather and other.factors,the thickness of ice on overhead power transmission line could be calculated.The experimental validation indicates that the scheme can monitor 30 mm ice thickness with is consistent 1 mm accuracy and sensitivity in 40 km distance.The experimental validation with the simulation analysis,which means that the scheme can effectively monitor the thickness of ice on long-distance overhead power transmission lines.
