Numerical Calculation of Overhead Power Lines Dynamics
Journal Title: Strojnicky casopis - Journal of Mechanical Engineering - Year 2016, Vol 66, Issue 2
Abstract
This paper contains results of transient analysis of airflow around the ACSR power line cross-section in unsymmetric multi-span. The forces applied to the power line are obtained from CFD simulations, where the wind induced vibration is studied. Effect of these forces to the maximal displacement of the power line and the maximal mechanical forces in the points of attachment are studied and evaluated.
