Abstract

A flow field model and a dynamic model of transmission line are introduced based on the analysis of micro-terrain effect on transmission line galloping. The dynamic simulation analysis was carried out for a transmission line with the consideration of micro-terrain influence, of which result was consistent with the practical observation. The results show that micro-terrain has significant effect on the transmission lines galloping characteristics of vibration mode and amplitude, with the comparative analysis of the simulation results with and without micro-terrain effect.

Key words
