Abstract
The goal of this project is to design a reliable high voltage overhead long transmission line that satisfies specific design criteria including voltage regulation, efficiency, surge impedance, surge impedance loading, sag and tension, and voltage gradient for corona loss. Various combinations of tower structures and conductors are tested with MATLAB, from which the combination yielding optimal results is selected. The proposed design consists of a lattice steel type 3L2 structure with ACSR 1192 kcmil. Fault analysis at three locations is performed using MATLAB and ASPEN’s One Liner program.
