【 摘 要 】

In the paper, the description of the type of vibrations of overhead transmission lines and theoretical background of spectral element method is presented. The main goal of this paper is to develop a model of the transmission line via spectral element method. The methodology of analysis is presented. Due to the accuracy of the results and the efficiency of the method, it is recommended to analyse the vibrations of the systems in various configurations of boundary and initial conditions. Numerical analysis investigates the natural frequency of the model due to different parameters, such as a tension force and the area of the cross-section of the conductor.
