MODELING OF CABLE VIBRATION FOLLOWING ICE SHEDDING PROPAGATION
The dynamic effects induced by ice shedding propagation on overhead transmission line cables are simulated numerically. The numerical model is validated by comparing simulation results to observations made on the full-scale test line of Hydro-Quebec. The uniform ice load is simulated by several concentrated loads acting at constant distances along the loaded span. Ice shedding propagation is then simulated through the removal in a defined sequence of the concentrated loads. The model thus built can predict some parameters describing the dynamic behavior of the span during the vibration following the ice shedding propagation. The numerically obtained results show close agreement with the experimental observations, which fact confirms the reliability of the model and its applicability for predicting the dynamic effects of ice shedding propagation on an overhead line conductor.
