Item Reducción del espacio de búsqueda aplicada a la planificación óptima de sistemas transmisión de energía eléctrica de gran escala(Universidad de Cuenca. Facultad de Ingeniería, 2025-09-24) González Cantos, Félix Sebastián; Torres Contreras, Santiago PatricioTransmission Network Expansion Planning (TNEP) is an essential activity to ensure that the electric power system can meet future demand at the lowest cost while meeting technical and environmental constraints. The current challenge for implementing any TNEP methodology is the computational complexity derived from the size of transmission systems and the high number of candidate lines, which results in large search spaces and therefore unmanageable computation times. For that reason, in this work, we propose a methodology based on Search Space Reduction (SSR) using clustering algorithms to produce a subset or group of candidate lines in which the optimal solution is ideally found. The performance of unsupervised algorithms such as Kmeans, PAM, and CLARA is compared, considering the overload, cost benefit, and least effort criteria as clustering methods. To validate that the search subspace contains the optimal solution, the Improved version of DE-PBILc hybrid metaheuristic (IDE PBILc) is used as an optimization technique. Finally, the methodology is applied to four electrical test systems of different scales: the 6-bus Garver system, the 24-bus IEEE system, the modified 118-bus IEEE system, and the modified 300-bus IEEE system. This results in significant reductions in processing time, 12.05%, 98.85%, 78.81%, and 95.76%, respectively, due to the reduction in computational complexity. It is also verified that the optimal solution is part of the subspace obtained for each of the test systems.Item Modelamiento e implementación vía simulación por computadora de un método de control de potencia y tensión basado en lógica difusa para sistemas fotovoltaicos en una microreed aislada(Universidad de Cuenca, 2024-09-05) Inga Cajamarca, Alen Andrés; Nivicela Marchán, Christian Esteban; Ochoa Correa, Danny Vinicio; Villa Ávila, Edisson AndrésIn this thesis, a model of an isolated microgrid is proposed, implementing a Fuzzy Logic (FL) based controller to smooth out power curves within the isolated microgrid. The FL-based controller allows the synchronous generator to operate without abrupt power changes, thereby ensuring robust system backup and extending the generator's lifespan. Additionally, the study implements a controller to stabilize the voltage at the load node, particularly when the loads begin to vary their consumption. To achieve this, irradiance curves previously recorded at the Balzay Campus Microgrid were used, and computer simulations of the components connected to the system under study were conducted. The simulations were based on the nameplate specifications of the components, which include: Synchronous Generator, PV System, Supercapacitor, and Variable Load. These simulations provided a solid foundation to evaluate the performance of the controlled environment and verify its correct operation. The proposed power and voltage controller achieves significant improvements, thereby ensuring its effectiveness.Item Estudio de pre-factibilidad para la integración de generación fotovoltaica en el alimentador S-0427 dentro del complejo hidroeléctrico Machángara por parte de la Empresa Electro Generadora del Austro ELECAUSTRO S.A.(2019-10-25) Tituana Tituana, Cristian John; Gonzalez Morales, Luis Gerardo; Sarmiento Vintimilla, Juan CarlosThis thesis shows the pre-feasibility analysis prepared in covenant with the Company Empresa Electro Generadora del Austro. This analysis is applied to the Complejo Hidroeléctrico Machángara where areas with sufficient properties for the integration of photovoltaic designs were determined through exploration. In addition, pre-feasibility level designs corresponding to each area are made for technical and economic evaluation. From the establishment of useful areas for photovoltaic generation and different alternatives of technical design at the prefeasibility level, the technical analysis and economic analysis are carried out under different financing scenarios. As a result, the necessary approximate budget, the average cost of energy production and the existence of pre-feasibility for the delimited sector are obtained. Finally, the existence of technical and economic pre-feasibility for the integration of photovoltaic generation for the Saucay, Dutasay and Labrado sectors was determined. Result obtained by determining the financing and technical design scenario that offers the highest cost-benefit ratio corresponding to each area.Item Coordinación de protecciones de la Refinería Shushufindi considerando el ingreso de un nuevo turbogenerador de 5 MW(2018) Simbaña Pulupa, Geovanny Enrique; Apolo Armijos, Ronald Vicente; Sanango Fernández, Juan Bautista; Zeas García, Serafín EuclidesThe Shushufindi Industrial Complex (CIS), with the purpose of improving the reliability, continuity and self-sufficiency of the electric power supply for the refining processes and not having dependence on the external network; plans to acquire a new generation unit with a rated capacity of 6.3 MW, which will be driven mechanically by means of a residual gas turbine as primary energy, which, for reasons of turbine efficiency and performance, will result in the generation of an effective maximum power of 5 MW. The input of this generation unit causes a change in the topology of the current network, so that the protection settings of each element within the system have to be readjusted. In this sense, the present project starts from the field survey of characteristics of the elements that make up the current network, as well as obtaining specific information about the equipment that will be part of the new system. For the modeling of the network, the use of a computational tool was chosen; where by simulations to different conditions of the system at maximum demand and steady state, the study of power flows and short circuits for possible faults in main bars was carried out in order to establish, according to the results obtained, an effective coordination of the protections considering the selectivity criteria and speed recommended by the regulations in force. Finally, the minimum technical characteristics of additional protection equipment of the new generation unit are determined.Item Manual de verificación y mantenimiento subestación eléctrica CC Santo Domingo(2018) Jaramillo Carrión, Luis Ramiro; Miño Santander, Luis Bolívar; Sempértegui Álvarez, Rodrigo EfraínThis document is a guide for the performance of both preventive and corrective maintenance work in the Electric Substation of the Paseo Shopping Mall in Santo Domingo.

The electrical equipment for maneuver, protection and electrical machines that contribute to the operation of the crushing plants and asphalt plant are old, so it is appropriate to evaluate the efficiency of the installed electrical systems. The driving forces for the equipment are driven by electric motors powered by turbo diesel generator sets. The energy audit process includes the collection of information, data analysis and decision making. This will be the initial information to determine the technical methodology in the energy consultancy to be applied and the subsequent technological update proposal that allows optimizing the production processes and the coordination of electrical protections under technical principles and job security.Item Sistema automatizado de mantenimiento centrado en confiabilidad (MCC) para proyectos de electrificación rural con sistemas individuales fotovoltaicos en la amazonía ecuatoriana(2014) Orellana Maldonado, Edwin Stalin; Porras Reyes, Jerfferson Alberto; Espinoza Abad, Juan LeonardoThe main objective of this research is to develop an automated system of Reliability Centered Maintenance (RCM) to enable the Regional Electricity Company CENTROSUR CA monitoring the operational reliability of the project "YantsaIi Etsari" (“Light from our sun”), contributing to its sustainability. The project is developed in the isolated communities located in the Amazon region, within the concession area of Centrosur (province of Morona Santiago). To achieve this objective an RCM methodology is proposed for the stand-alone photovoltaic (PV) systems that are part of the project, using the technique Failure Mode and Effects Analysis (FMEA), which is based on calculating Risk Priority Index (RPI) in order to prioritize the potential cause of failure for possible corrective actions. Data collection was approached in two phases.The first phase consisted of collecting historical failure data in equipment of stand-alone photovoltaic systems of the Yantsa Ii Etsari project, information available in the Centrosur CA database. In the second phase, the authors conducted field visits to twenty five Amazonian communities benefiting from the project in order to collect data through surveys as well as visually checking the status of PV systems. With the raised information, an analysis was performed to prioritize critical equipment using the technique Criticality Analysis (CA), and once the equipmentwas hierarchized, possible causes of the failures were identified through the technique Root Cause Analysis (RCA). Finally theRCM methodologywas implemented in Microsoft Access software, indicating the steps to follow for optimal use of this automated system and demonstrating, through an example,how effective might be RCMin regard to maintenance of stand-alone photovoltaic systems of the Yantsa Ii Etsari project.Item Demanda eléctrica en instalaciones residenciales y comerciales(1988) Avila G., Edgar; Picón B., Efraín M.; Jaramillo Paredes, FabiánItem Selección óptima de unidades térmicas de generación utilizando programación entero-mixta(1987) Alvarez A., Willam; Arizaga P., Galo; Durán Noritz, CarlosItem Estudio de las protecciones del anillo de 69 Kv. del Sistema Regional Centro Sur(1985) Ortiz Larrea, Juvenal; Mora Espinoza, Santiago; Carrillo Torres, HernánItem Ubicación óptima de la nueva subestación alta tensión media tensión en la zona urbana de Cuenca(2006) Machado Solís, Jorge Santiago; Albornoz Vintimilla, Claudio EstebanItem Diseño de una red GSM para los cantones de: Cuenca, Paute, Gualaceo, Chordeleg, Girón y Santa Isabel(2002) Pinos Espinoza, Hugo Alejandro; Urdiales Flores, Luis Eduardo; Andrade Rodas, Juan ManuelItem Diseño y construcción de un sistema de comunicación digital mediante modulación delta, codificación de canal, modulación FSK y transmisión por rayos infrarrojos(Universidad de Cuenca, Facultad de Ingeniería, 1993) Brito Mancero, Fabián; Peñaherrera Calle, Miguel; Doutreloigne, JanItem Evaluación y operación de luminarias para alumbrado público(1992) Díaz Guillén, Miguel; Peña Cisneros, Petronio; Sempértegui Álvarez, Rodrigo EfraínItem Análisis de la confiabilidad de servicio en sistemas de distribución(1991) Arévalo P., Hugo; Neira C., Diego; León Córdova, Pedro AlejandroItem Adquisición de datos de las variables de los procesos de la planta de fuerza del molino papelero CARTOPEL(2011) Guamán Sánchez, Cristian Fernando; Bravo Padilla, Eddy Gabriel; Larco Barros, Ciro Mauricio
