Diseño óptimo de instalaciones eléctricas considerando cableado convencional y blindo-barras mediante decisión multicriterio con objetivos de calidad, eficiencia y costos

Abstract

The following development project is focused on the optimal design of electrical installations, in which conventional cabling and busbars were considered through multi-criteria decision-making regarding efficiency, cost and quality. For this purpose, a simulation of fifteen scenarios was carried out, where a base diagram was executed which determines the lengths and technical-electrical parameters. In addition to this, it should be noted that for the diagram mentioned above, nine connection sections are defined, which vary according to each of the scenarios mentioned. However, the diagrams for each of these scenarios were modeled and schematized using DIGSILENT® software. Where it was possible to determine the behavior of three different variables for the fifteen scenarios, which were losses in kilowatts, voltage deviation and costs. Once the values of these three variables were determined for the fifteen scenarios, the multi-criteria analysis was applied through the CRITIC method using MATLAB software, where the three different criteria were applied; In the first criterion, a greater weight was assigned to the voltage deviation variable, in the second criterion a greater weight was considered to the kilowatt losses variable and in the third criterion a greater weight was established to the cost variable. With these three criteria the following results were obtained; criterion 1: optimal scenario 3, criterion 2: optimal scenario 3 and criterion 3: optimal scenario 7. Once these results were obtained, through the CRITIC method it was possible to determine that the optimal winning scenario would be number 3, that is, the implementation of busbars in the first five sections and the implementation of conventional cabling in the last four sections
