High Voltage Transmission Line Vibration: Using MATLAB to Implement the Finite Element Model of a Wind-Induced Power-Line Conductor Vibration

Abstract

Wind-induced vibration affects the performance and structural integrity of high voltage transmission lines. The finite element method (FEM) is employed to investigate windinduced vibration in MATLAB. First, the FEM model was used to develop the equation of motion of the power line conductor. In addition, dampers, conditions for damping, free and forced vibrations of the overhead conductor were considered in the FEM model. Wind-induced experiments were conducted in the laboratory using an actual overhead power conductor. The developed FEM models were simulated in the MATLAB computing environment. The results from the MATLAB simulation, finite element and experimental recordings were compared in order to evaluate the efficacy of models simulated in MATLAB and developed using the FEM.
