Actualización y coordinación de las funciones de protección de las Centrales Saucay, Saymirín, El Descanso y Ocaña
(2016) Astudillo Calle, Jorge Eduardo; Pinos Narváez, Wilson Stalin; Quizhpe Huiracocha, Kléver Leonardo
This present study develops a proposal to upgrade protection functions of various Intelligent Electronic Devices (IED’s) with digital technology, which protect generators and transformers of Saucay, Saymirin, El Descanso and Ocaña power plants belonging to Elecaustro S.A. Also a proposal to activate new protection functions is made, especially on Saucay, Saymirin III, IV and El Descanso plants, where electromechanical relays were replaced by IED’s in the past. To know which protection function needs to be updated or activated, it is carried out a comparison between the recommended protection functions by the standards: IEEE Std C37.102-2006 for AC generator protection, IEEE Std C37.91-2008 for transformer protection and the protection functions that currently have the installed IED’s. Also a new proposal for coordination of overcurrent functions that protect generators, transformers and transmission lines is performed, considering that all plants belonging to Elecaustro S.A are embedded in the 69kV subtransmission system belonging to EERCS. Finally, with the help of the software DIgSILENT PowerFactory, various failures are simulated at different points of the grid to make a contrast between existing and proposed trip times.

Alternativas de expansión del área de cobertura de la Subestación 14 Léntag
(2019-10-22) Estrella Nieto, Christian Fernando; Salgado Rodríguez, Modesto Enrique
The purpose of this work is to evaluate various alternatives for the expansion of the sub transmission system in the southern zone of the province of Azuay, served by the Léntag substation, due to the entry of important charges for mining concessions that will come into operation in the sectors of Rio Blanco, Loma Larga and San Gerardo. It is based on a demand projection study for several growth scenarios that cover a period of 15 years. For the spatial projection of the demand the methodology of micro areas is used which allows to determine the quantity of new clients and where they will be located, as a result a map of preferences for the different categories of consumption is obtained, to later convert these preferences in electrical demand obtaining a map of spatial projection of the demand for the area of study. With the projection study and the demand values of the mining projects, different options for the supply of electrical energy are evaluated evaluating technical and economic aspects, considering the implementation of infrastructure such as the construction of new substations and sub transmission lines and the evaluation of the distribution system at the 22-kV level with the new loads. The final result is the choice of the most favorable expansion alternative in order to supply electrical energy in compliance with quality standards according to current regulations.

Análisis de calidad de energía eléctrica de un sistema hospitalario “básico de segundo nivel” suministrado por la red convencional y su mejora mediante energía solar fotovoltaica
(Universidad de Cuenca, 2020-10-16) Lata Chuqui, Milton Geovanny; Sánchez Aucay, Andrés Ismael; Mogrovejo León, Wilson Fernando
At present, it is necessary to develop electricity generation alternatives aimed at taking advantage of natural resources that reduce energy dependence from polluting sources. The present work proposes alternatives to photovoltaic systems connected to the electrical network to solve the problems of electrical power quality in the San José de Taisha Hospital, located in the Taisha canton. The Energy Quality analysis was performed in the hospital center, taking into account the ARCONEL regulation No. 005/18 section 5.1.1 product quality. The project is based on the search for viability at the pre-feasibility level of the technical application of a photovoltaic system as a solution to the energy quality problems that the hospital center presents. Therefore, a photovoltaic generation system is dimensioned based on the ARCONEL Regulation No. 003-18, called photovoltaic generation for selfsufficiency of final consumers of electric energy; several technical alternatives are presented for the dimensioning of the photovoltaic generation system. For the analysis of the photovoltaic potential at the site, a data collection circuit was designed consisting of a Raspberry pi three single-board computer and a solar radiation sensor.

Análisis de cargabilidad de transformadores de distribución de la Empresa Eléctrica Centro Sur CA y su impacto técnico y económico
(Universidad de Cuenca, 2024-09-23) Sánchez Vásquez, Jorge Isaac; Ulloa Rodas, José Ignacio; Albornoz Vintimilla, Claudio Esteban
In the distribution of electric power, transformers are essential, since they allow the transfer of energy from medium to low voltage, adjusting to the needs of end users. Empresa Eléctrica Regional CENTROSUR faces the challenge of ensuring the efficiency and reliability of its distribution transformers, both technically and economically. This degree work performs a detailed analysis of the loadability and efficiency of this equipment in CENTROSUR, covering technical, operational and economic aspects, such as oversizing and associated losses. Since energy demand and installed capacity do not always grow at the same rate, it is crucial to perform a thorough evaluation to optimize transformer sizing. The research is organized in chapters that explain from the operation of transformers and their components, to a comparative analysis of sizing methodologies used by other distribution companies in the country. It also includes an analysis of loss costs under different scenarios of the utilization factor in the distribution system, considering two specific cases of transformers, implementing measurement curves and overload criteria established by the ANSI/IEEE C57.91-1981 standards and the Colombian Technical Guide GTC 50. This degree work seeks to propose more efficient practices in the management of distribution transformers, with the objective of reducing energy losses and improving professional practices in the electric distribution network of Empresa Eléctrica Regional CENTROSUR.

Análisis de conductores de alto desempeño (HPC y HTLS) en la expansión de sistemas de transmisión de energía eléctrica
(Universidad de Cuenca, 2025-09-25) Barrionuevo Ortega, Daniel Enrique; Torres Contreras, Santiago Patricio
The sustained growth in electricity demand and the technical limitations of transmission networks have driven the need for innovative technologies that enhance system efficiency and reliability without requiring major infrastructure investments. In this context, high-performance conductors (HTLS) emerge as a viable alternative to conventional ones, as they allow operation at higher temperatures without compromising mechanical stability or operational safety. This thesis evaluates the incorporation of HTLS conductors in power system expansion through a comparative technical-economic approach using three representative test systems. To solve the expansion planning problem, a metaheuristic was implemented in combination with an AC optimal power flow model using MATPOWER. The selection of candidate lines was based on technical and economic criteria, and scenarios with different cost proportions for HTLS conductors were analyzed to assess the feasibility of their implementation and the potential advantages they could bring to the grid, such as reducing investment costs or increasing system loadability.
