Dynamic Modeling of Galloping in Overhead Transmission Lines

In this paper, a dynamic model of single conductor overhead lines with vertical motion is investigated and according to applicable differential equations, this model is simulated for important types of galloping. Therefore by doing this simulation, maximum galloping amplitude is estimated and the effect of wind velocity on maximum galloping amplitude and its frequency is also evaluated.
