Dynamic Response of Overhead Transmission Line in Turbulent Wind Flow with Application of the Spectral Element Method

Abstract

In the paper, the response of overhead transmission line in turbulent wind flow with use of the spectral method is investigated. The analysis is performed for wind flow model that reflects the real conditions. Numerical analysis investigates the vibrations of the conductor due to different parameters of turbulence. For comparison, the excitation of the sine function is investigated. Spectra of longitudinal wind velocity for the numerical case, as well as the spectra of Karman, FSU and the proposal of author's models are analysed. Couniham and ESDU integral length scale are performed.
