Geometrical Approximation of the Overhead Power Line Conductors

Abstract

A numerical algorithm for segmentation of overhead power line conductors, which form a catenary, for 3D electric and magnetic power frequency field computation is presented. The overhead power line conductor catenary is approximated by a set of straight thin-wire segments. The segmentation algorithm requires only three input data per power line span conductor - the global coordinates of power line span conductor endpoints and the height of the lowest conductor point. On the basis of the presented theory, a FORTRAN program was developed and results of the overhead power line conductor segmentation with different number of straight segments along the span are compared and graphically presented
