The present titling work presents a prefeasibility study that proposes alternatives of photovoltaic systems connected to the electricity grid, to cover the energy demand of the existing loads in the El Descanso thermoelectric power station, located in the El Descanso sector, Azogues, province of Cañar. The study starts with the analysis of Regulation 003/18, issued by the ARCONEL, called photovoltaic generation for self-supply of final consumers of electrical energy. The project is based on two analyzes: on the one hand, the search for feasibility at the prefeasibility level of the technical application of a photovoltaic system and on the other hand the economic evaluation of the project. Several technical and economic alternatives are presented for the development of the degree work. Information is collected using primary sources such as the weather station owned by ELECAUSTRO, located at the El Descanso thermoelectric plant. This information allows the technical feasibility to be evaluated using current and more efficient technology, thus allowing the existing solar resource in the area to be used as much as possible. As for the economic evaluation, current prices allow estimating investment costs for each of the technical alternatives proposed and thus determine the economic viability of each.Item Estudio para la implementación de una plataforma de mensajería corta para la red de telefonía fija de etapa en el cantón Cuenca(2008) Calva Sarango, Jairo Lenin; Lazo Castro, Pedro Vicente; Sempértegui Álvarez, Rodrigo EfraínItem Estudio preliminar para generación hidroeléctrica en las redes de agua potable de Etapa(2005) Bernal Bernal, Aurelio Armando; Sempértegui Álvarez, Rodrigo EfraínItem Estudio sobre el aprendizaje organizacional y la administración del conocimiento en las empresas basado en el pensamiento sistémico(2010) Espinoza Veintimilla, Angel Oswaldo; Sempértegui Álvarez, Rodrigo EfraínItem Estudio telefónico actual y futuro para la zona de el Ejido(1994) Jara C., Jorge R.; Pauta A., Fausto R.; Sempértegui Álvarez, Rodrigo EfraínItem Evaluación del subsidio al gas licuado de petróleo en el Ecuador(2015) Polo Avilés, María Verónica; Sempértegui Álvarez, Rodrigo EfraínIn the field of energy subsidies have been disseminated worldwide, trying to achieve several objectives, among them the introduction of new energy sources. The high fiscal cost generated by the use of subsidized LPG in Ecuador and socio-political impacts that can generate a decision of the Ecuadorian government with respect to the price of liquefied petroleum gas, demand evaluation using multi-criteria analysis of several scenarios which They are: Maintain the current subsidy (BAU) Raise the price of domestic LPG cylinder from US $ 1.60 to US $ 5.00, subsidize the consumption of LPG for cooking for quintiles 1 and 2 of the Ecuadorian population and finally replace the use of LPG for cooking electricity for all Ecuadorians homes. The mathematical models used are: Quipu is a compensatory model - no compensatory and ELECTRE III based on the concordance and discordance between variables. After applying the models obtained indicated that the alternative commitment to the evaluated criteria is to replace the use of LPG for cooking electricity for the Ecuadorian households.Item Evaluación y operación de luminarias para alumbrado público(1992) Díaz Guillén, Miguel; Peña Cisneros, Petronio; Sempértegui Álvarez, Rodrigo EfraínItem La generación distribuida y sus retos frente al nuevo marco legal del mercado eléctrico ecuatoriano(2013) Durán Contreras, Edgar Fernando; Sempértegui Álvarez, Rodrigo EfraínTraditional centralized schema evolution of Electric Power Systems requires paradigms change and distributed generation emerges as a solution to the growing need for alternative energy sources. Distribution systems are designed for a unidirectional flow to customers, several studies suggest as a solution to the technical and safety issues to take into account of Distributed Generation , by location and simple mode of operation, always with a focus on to minimize negative impacts on the management and operation of the original distribution systems . Importance of security and diversification of the energy mix, renewable energy to reduce dependence on fossil fuels, promotes the development of renewable resource projects while issuing and updating of the Regulations by the CONELEC, support their evolution. The use of distributed generation can provide improvements in power quality, fundamental aspect of production systems. On the other hand, large-scale integration of distributed generation in the distribution network would create a technical, economic and regulatory complex and requires innovative solutions should seek to establish clear rules from the beginning.Item Identificación de viviendas afectadas por el alumbrado público (polución lumínica) en la ciudad de Cuenca(2018) Sacta Pérez, Jorge Luis; Sempértegui Álvarez, Rodrigo Efraín; Pulla Galindo, Giovanni Santiago; Arévalo Pesántez, Hugo SantiagoLight pollution is any unused light energy that can cause negative effects in the environment, such as the emission of light flow in areas or in directions that should not be illuminated. The main objective of this study is to quantify the amount of unnecessary light produced by public lighting that is focused on the facades of existing buildings in Cuenca’s historic downtown, as well as estimate the energy consumed to illuminate these areas. Chapters 1 and 2 describe the concepts related to public lighting and light pollution.
