Optimización multiobjetivo en sistemas de puesta a tierra para subestaciones de potencia considerando la longitud de conductor.

Abstract

Grounding systems are of great importance in electrical engineering, they allow unwanted currents to escape to maintain the safety of the system to be protected, the design of a grounding grid is affected by the terminology when using the standards electrical, in the IEEE Std. 80-2013 standard there are steps to follow for the design of a grounding grid, oversizing the driver to comply with the imposed restrictions from the technical and safety point of view, thus achieving a system reliable in case there is an anomaly within a substation. In this work an algorithm is developed that minimizes the length of conductor for a grounding mesh, fulfilling the restrictions that are in the norm, this algorithm uses the Pareto method focused in the multiobjective problematic, that allows to minimize the conductor between bare conductor and rods, without transgressing the limits of voltages described.
