Plataforma homologada al contexto ecuatoriano para el diseño y dimensionamiento preliminar de subestaciones eléctricas ≤ 24 MVA

Abstract

CONDITIONING OF PROJECT PUBLICATION. The growth of projects in Ecuador has increased the need for adequate electrical infrastructure to ensure proper operation. In medium and large-scale projects, this requirement often leads to the implementation of electrical substations, where the scope of the required infrastructure is not always clearly understood, thus hindering effective decision making. In this context, the objective of this work is to develop an application adapted to the Ecuadorian context, while maintaining technical and regulatory criteria, enables the preliminary design and sizing of electrical substations with capacities of up to 24 MVA. To achieve this, a structured and modular methodology was applied, including demand estimation, selection of substation type, and preliminary sizing of infrastructure and equipment, considering representative configurations of AIS and GIS substations, as well as the generation of technical deliverables. As a result, DIMSUB-24 was developed as a functional application capable of generating coherent technical configurations, thereby facilitating the understanding of the electrical infrastructure required for a substation. The application was validated through three groups of users, which collectively demonstrated its potential for growth, practical usefulness, and educational value. Consequently, this work establishes a referential basis that contributes technical clarity to decision-making processes in substation projects. Keywords: Electrical substations, preliminary sizing, technical deliverables, application adapted to the Ecuadorian context.
