159 Aeolian Vibration Monitoring Technologyof Wire in Smart Grid

The influence of Aeolian vibration is a common problem in the overhead transmission line. It sometimes leads the conductor wire broken off. All of these will threat the safe operating of transmission line. Researching on fatigue property and Aeolian vibration performance, and then predicting the life of wire, provide a concrete support to formulate an effective measure of anti-vibration. Bending amplitude and Dynamic bending strain can be calculated and computed by our monitoring model depending on the generating principle combined with the bending amplitude method in this paper. A prototype monitoring system is developed to realize the effectiveness of our model.
