Particle Swarm Optimization with multi-ring topology applied to the optimization of power transmission line parameters

This paper proposes a method to assist the monitoring of power transmission lines, essential task to the electric industry operators. It is applied the Particle Swarm Optimization metaheuristic with multi-ring topology to obtain the cable-ground height, the distance between phases, the equivalent diameter of conductors, the currents and voltages, through a cross-section of a transmission line, using the reference values of the electric and magnetic fields. Due to the simplicity of implementation, the low runtime and the small error obtained, the proposed method is feasible and promising for monitoring transmission lines.
