Resumo
This dissertation of master degree describes methods of optimizing routes and allocating towers
of overhead power lines, with the objective of meeting technical, structural and constructive
constraints, and reducing financial costs. The generated solutions are graphically presented
through the transmission line profile and its 3-dimension representation upon the elevation map of
the area. For the projects evaluation, elements of structural analysis are used, highlighting the
Matrix Structural Analysis for the study of efforts and deformations in the towers and their
components. Three methods are proposed, each one using different approaches. First, it will be
shown an optimization algorithm based on Evolutionary Computation, characterized by the
application of natural selection on individuals generated from mutations and genetic crossover.
The second algorithm was inspired by the well-known Nelder-Mead optimization method. The
triangular transformations addressed in the original method were adapted and physically
implemented to transmission lines. The last optimization algorithm presented is a hybridization of
the two previous methods. Finally, a performance comparison of the algorithms, in which each
one of them will be applied to three different cases, will be carried out in order to validate them.
