Diseño de un algoritmo de optimización para sistemas de puesta a tierra en subestaciones eléctricas implementando algoritmos genéticos

Abstract

Context: At present the programs for the design of systems of grounding have a high cost for their acquisition, as also the elaboration in geometric aspects of the mesh is empirical, which generates losses in the costs of its implementation. Method: To carry out the design of the grounding system following the guidelines and restrictions of the IEEE80, in the interface of the DESAG program the user enters data related to the mesh as they are; length of available terrain, available terrain width, terrain resistivity, among others, once this data is entered, DESAG automatically designs the grounding grid and delivers the data as results; length of the mesh, width of the mesh, spacing between conductors, among others, as well as a figure of the mesh made in 2D. Results: Performance tests were carried out which aimed to verify the proper functioning of the DESAG program, confirms the reliability and accuracy of DESAG by comparing the results obtained with the ETAP software grounding system module obtaining the most relevant result calculation errors below 0.5%.Conclusions: The algorithm designed complies with the guidelines and restrictions of the IEEE80 (2000), the meshes made by DESAG guarantee optimally the design of the grounding mesh due to the decrease of the real step and contact voltages with respect to the voltages of tolerable step and contact required by the standard.
