提出了一种基于光纤布拉格光栅（FBG）拟合传感器的输电线路驰动监控方法，并在架空输电线路实验中通过视频监控方法进行了验证。该方法可同时实时测量线张力、驰动模式以及水平和垂直方向的幅值。通过92 h的输电线路驰变结果验证了该方法的作用，并分析了风速和风向对驰变测量的影响。与视频监控方式相比，具有能够测量线的张力和驰骋方式、驰骋幅度监测分辨率更高、不受天气条件影响实时监控等优点。该方法可广泛应用于输电线路监测，对推进智能电网建设具有积极意义。
A method of monitoring the transmission line galloping based on a fiber Bragg grating (FBG) fitting sensor is proposed and verified by the video monitoring method in the overhead transmission line experiment. The proposed method can be used to measure the line tension, the galloping mode, and amplitude in horizontal and vertical directions in real-time, simultaneously. The functions of this method were confirmed by the 92-h transmission line galloping results and the influence of the wind speed and direction to the galloping measurement were also analyzed. Compared with the video monitoring method, it has the advantage of being able to measure the tension and galloping mode of line, higher resolution of galloping amplitude monitoring, and real-time monitoring regardless of weather conditions. This method can be widely used in transmission line monitoring and has positive significance to promote the smart grid.
