Abstract:
Based in the collecting of dates weathers conditions during years in Albania, in this paper we study possibility of occurring of phenomena of “galloping” in overhead transmission line. A numerical analysis is presented in order to simulate galloping type motion of transmission line. Computerized simulations can simulate numerous cases and determine the influence of diverse parameters on galloping, as well as "pre-test" a future line before building it. Many models have been developed for the simulations based on differential equations solving or on finite element modeling. The proposed methodology is based on differential equations modeling of the transmission lines for simulation of galloping. A simulation program that can simulate transmission lines motion taking effects of the ice and wind to clarify the characteristics of the galloping phenomenon, and to establish a rational design method for galloping it is developed. With help of software SAMCEF Version 6, tests have been done in a span of Mati river, to define the measures to be undertaken to eliminate the damages of this phenomena.
