dc.description.abstractIntroducción: Actualmente en Colombia, existe gran interés por la aplicación de energías renovables y la diversificación de la matriz energética. Por lo tanto, en el presente trabajo se muestran los resultados de la simulación de una planta solar térmica hibrida de ciclo Brayton cerrado en Colombia, que recibe calor de un sistema de concentración de torre central y heliostatos. El recurso solar se estima por un modelo horario, adicionalmente cuenta con una cámara de combustión que utiliza gas natural como combustible, la cual garantiza la estabilidad del calor suministrado a la planta. La ubicación de la planta se selecciona en función de la radiación global y difusa media diaria mensual, y adicionalmente, se realiza una simulación de los principales parámetros de operación, optimizando la potencia y el rendimiento global en función de la relación de presión. Por último, se realiza un análisis exergético de la planta, especialmente de los componentes afectados por la variación de la radiación en el día. Objetivo: Evaluar una planta solar térmica de concentración de ciclo Brayton cerrado, desde el punto de vista energético y exegético bajo las condiciones ambientales de Colombia. Metodología: Integrar en lenguaje modélica, por medio de un compilador Dymola un modelo de recurso solar, un modelo energético y un modelo exergético aplicado a las condiciones ambientales de Colombia. Resultados: Se presenta el análisis correspondiente a la evolución de los principales parámetros de operación de la planta a lo largo del día, la variación del rendimiento y la potencia en función de la relación de presiones. Conclusiones: Es viable técnicamente la operación de una planta solar térmica de concentración de ciclo Brayton en algunos lugares de Colombia, dado el recurso solar disponible y el ahorro de combustible que genera a pesar del detrimento del rendimiento energético y exergético.es_ES
dc.description.abstractIntroduction− Actually in Colombia, there is great inter-est in the application of renewable energy and the diversi-fication of the energy matrix. Therefore, in this work, are presented the results of the simulation of a hybrid solar thermal plant of closed Brayton cycle in Colombia, that re-ceives heat from a concentration system of central tower and heliostats. The solar resource is estimated by a time model validated initially, additionally with a combustion chamber that uses natural gas as fuel, which guarantees the stability of the heat supplied to the plant. The location of the plant is selected based on the global and diffuse average monthly radiation per day, and additionally, a simulation of the main operating parameters is carried out, optimizing the power and overall performance as a function of the pressure ratio. Finally, an exergy analysis of the plant is developed, especially of the components affected by the variation of the radiation during the day.Objective−Evaluate a thermal solar plant of closed Brayton cycle concentration, through an energetic and exegetical analysis under the environmental conditions of Colombia.Methodology−Integrate a model of solar resource, an energetic model and an exergy model applied to the envi-ronmental conditions of Colombia in model language in a Dymola compiler.Results− The evolution of the main operating parameters of the plant throughout the day, the variation of the perfor-mance and the power depending on the pressure ratio are presented and analyzed.Conclusions−It is technically feasible the operation of a solar thermal plant of concentration of Brayton cycle in some places of Colombia, given the available solar resource and the fuel saving that it generates despite the detriment of the energetic and exegetical performance.es_ES
