Abstract :
A full multi-span three-degree-of-freedom (3-DOF) iced power transmission line model is presented. This new model is applicable for describing the galloping phenomena of both single and bundle lines, for performing static and dynamic analysis, and predicting the galloping behavior of iced power transmission lines, as well as for performing checks against field experience. Some applications for overhead power transmission lines design are detailed. Some original recommendations for the design of multi-span bundle configurations are also proposed
