Application of Monitoring Technology Based on Aeolian Vibration in Smart Grid
The aeolian vibration of overhead transmission lines frequently brings about the breaking fatigue of wires, which makes a serious threat to the security of transmission lines.Today, more and more attentions have been paid to the aeolian vibration both in research and commercial realms . As aeolian vibration monitoring can accurately monitor wire damage, it is conducive to timely maintenance and avoiding accidents. In our paper, we propose a system model adopting bending amplitude method to estimate bending amplitude, calculate dynamic bending strain of wire and obtain early warning tips by comparing with strain chart based on the research of principles of aeolian vibration. Besides, A prototype system is developed to realize the effectiveness of the proposed model.
