Estudio para la implementación de una subestación tipo interior de 300KVA/13.8KV/127V-220V para un edificio de uso público

Abstract

This degree project focuses on the Study for the Implementation of an Indoor Substation of 300 kVA/13.8 kV/127 V-220 V for a Public Use Building. This work arises because the current 150 kVA substation has reached its capacity limit, making its redesign necessary to ensure a reliable and safe electrical supply capable of meeting the building's current and future needs. During the development of the project, the present and future load capacity of the building was evaluated to correctly size the proposed transformer. Short-circuit studies were carried out using ETAP software, which allowed for the selection of suitable equipment for the new substation, including transformers, protection systems, and switches. Additionally, the grounding system was designed using ETAP software, meeting established safety and reliability standards. As part of the project, a preliminary design was developed, including the single-line diagram and the layout of the main components. Furthermore, simulations of acceptance tests and commissioning were conducted to ensure the proper functioning of the substation. The result of this work aims not only to optimize the building's electrical performance but also to serve as a reference for future similar projects. This document is intended to help other professionals improve and update the electrical systems applied in such infrastructures, integrating more modern and efficient technologies.
