Development of Fiber Bragg Grating Wind Sensor for Icing-monitoring of Overhead Transmission Lines
摘要
Abstract
Measurement of wind load is an essential part of icing monitoring on overhead transmission lines. To overcome the drawbacks of the existing wind sensors, such as the requirement for field power, the sensitivity to electromagnetic interference (EMI) and the unavailability of real-time measurement, a novel wind sensor was developed on the basis of the fiber Bragg grating (FBG) sensing technique. In the sensor, a beam with uniform strength was used to measure the pressure caused by wind speed; two naked FBGs were symmetrical glued on the upper and lower surface of the beam to solve the problem of cross-sensitivity between strain and temperature of FBG sensing. The temperature effect on zero output was investigated by putting the FBG sensor into a oven, and the experiment results indicated the temperature effect on the wind speed zero output was less than ±5pm. The results of wind tunnel experiment indicated that the sensor has the advantages of lower non-linear error with the measurement error of less than ±0.5m/s. The ice load error caused by the wind measurement error was calculated with the relative error of less than 2.14%. These parameters of the proposed FBG wind sensor are suitable for ice monitoring on overhead transmission lines.关键词
