Research on Ice Monitoring on Overhead Power Transmission Lines with Parabola Method and Optical Fiber Sensing Technology
采用抛物线法，分析并建立了架空输电线覆冰厚度与轴向应变的理论关系模型，进而提出并实验验证了一种基于光纤布拉格光栅(Fiber Bragg grating, FBG)应变传感器的架空输电线覆冰厚度监测方案。实验结果显示在30mm等效覆冰厚度载荷范围内该方案最大测量误差为2mm。该方案可实现远距离无源化监测，且具有安装简单、应用灵活等特点，是一种极具应用潜力的架空输电线覆冰厚度监测方案。
With Method of parabola, a theoretical model of relationship between depth of ice and axial micro-strain on overhead transmission lines is analyzed and established. Furthermore, a scheme for ice monitoring on overhead transmission lines based on FBG sensors is proposed. Maximum deviation of 2mm is experimentally verified. Remotely passive monitoring is achieved by scheme proposed with features of simple installation and flexible application.
