Self-excited generator: off-grid operation without energy storageGenerador autoexcitado: operación en red aislada y sin almacenamiento energéticoThis article covers the analysis and simulation of an off-grid electrical generation system based on renewable sources without energy storage. First of all, strategies for regulation of DC link voltages are proposed for a photovoltaic unit and a self-excited generator. In the first case, a modified maximum power point tracking algorithm has been implemented. For the self-excited generator, a combination of mechanical (turbine), electromechanical (induction machine), electrical (rectifier) and electronic (PI control of power converter) conversions, were performed. Hence, after having regulated the input voltage of the power inverter, all the effort relied on a droop controller allowing power sharing to distribute reasonably the demand among generators of the grid. The proposed system is potentially a low-cost solution for electrification of rural zones of Colombia.El presente artículo aborda el análisis y la simulación de un sistema de generación eléctrica basado en fuentes renovables, operando aislado y sin almacenamiento de energía. Inicialmente, se proponen estrategias de control individual para garantizar regulación en la tensión del bus DC. Para un sistema fotovoltaico, se considera la modificación de un algoritmo de seguimiento del punto de máxima potencia. Para un generador autoexcitado se construye una combinación de conversión mecánica a través de turbina, conversión electromecánica vía generador de inducción, rectificación trifásica y regulación de tensión vía lazo de control PI. A partir de ello, un control droop demuestra un apropiado reparto de potencias entre las diferentes unidades de generación. La topología de sistema propuesta es aplicable como solución de electrificación de bajo costo en zonas rurales de Colombia.Universidad Católica de Pereira2023-08-29T03:49:40Z2023-08-29T03:49:40Z2022-01-31Artículo de revistahttp://purl.org/coar/resource_type/c_6501http://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionhttp://purl.org/coar/resource_type/c_2df8fbb1application/pdfhttps://revistas.ucp.edu.co/index.php/entrecienciaeingenieria/article/view/263210.31908/19098367.2632http://hdl.handle.net/10785/13696Entre ciencia e ingeniería; Vol 15 No 30 (2021); 57-62Entre Ciencia e Ingeniería; Vol. 15 Núm. 30 (2021); 57-62Entre ciencia e ingeniería; v. 15 n. 30 (2021); 57-622539-41691909-8367spahttps://revistas.ucp.edu.co/index.php/entrecienciaeingenieria/article/view/2632/2472Derechos de autor 2022 Entre Ciencia e Ingenieríahttps://creativecommons.org/licenses/by-nc/4.0/deed.es_EShttps://creativecommons.org/licenses/by-nc/4.0/deed.es_ESinfo:eu-repo/semantics/openAccesshttp://purl.org/coar/access_right/c_abf2Forero Ordóñez, Fabián LeonardoAlzate Castaño, RicardoVega Pérez, Carlos Jesúsoai:repositorio.ucp.edu.co:10785/136962025-01-27T23:58:31Z |
