Development of FEM methodology for analyzing wind-induced loads on transmission lines for sub-arctic terrain and extreme atmospheric conditions

Abstract

This thesis presents structural analysis of power lines with the use of the Finite Element Method (FEM). The methodology of analyzing the atmospheric loading on conductors and supporting structures is being developed. The introduction to the problematics of climatic loading that impact transmission lines is proceeded with review of design codes for determination of resulting loads on supports. The final stage is to create parametrized model of suspension structures coupled with conductors in MATLAB and COMSOL Multiphysics software with adequate modelling techniques and boundary conditions. As a result, master thesis contributes to development of structured procedure of overhead transmission lines design in order to facilitate the structural assessment and address the commercial needs.
