Abstract
En este proyecto se diseña una central termosolar de 50 MW utilizando colectores cilindro parabólicos. Se han evaluado las diferentes tecnologías disponibles y se detalla por qué se ha optado por captadores cilindro parabólico.
Se ha elegido Toledo como ubicación de la planta termosolar. Para determinar la viabilidad del emplazamiento de la central, se han considerado una serie de parámetros, de los cuales la radiación normal directa (DNI) ha sido determinante.
Con el objetivo de satisfacer la demanda, se ha dotado a la central de un sistema de almacenamiento térmico mediante sales fundidas, que permite conservar la energía térmica que no ha sido utilizada por el bloque de potencia de la planta.
Además se ha estudiado la posibilidad de añadir un 15% de apoyo de combustible fósil a la central termosolar, y cómo afecta esto a la su producción.
Para la simulación de la central, se ha utilizado el programa System Advisor Model, que proporciona datos sobre el dimensionamiento del campo solar, el funcionamiento y la producción eléctrica de la planta, así como el coste de la central y el precio de la energía producida.
Por último, se han expuesto las conclusiones obtenidas tras la realización de este proyecto y se han propuesto futuros estudios a realizar sobre el presente diseño. Además, se ha comentado brevemente las líneas de investigación que se están llevando a cabo en el terreno de la energía termosolar con concentradores cilidro parabólicos.
This project is intended to design a thermosolar power plant of 50 MW usingparabolic trough colectors. Different available technologies have been evaluated and it is detailed why parabolic trough colectors have been chosen. The selected location of the thermosolar power plant is Toledo (Spain). To determine the feasibility of the named location, several parameters have been considered, of which Direct Normal Irradiation has been decisive. With the aim of meeting the demand for electricity, a storage system of moltensalts has been added to the power plant. It allows the power plant to keep the thermal energy which has been not used by the power block. Besides, it has been studied the possibility of providing the power plant with a 15% of auxiliar ysystem with fossil fuel, and how it affects to production. For simulating the power plant, a software called System Advisor Model has been used. It can account for data about solar field sizing, operation and electricity production of the power plant, as well as costs and produced energy price. Finally, findings have been presented and future studies over the current design have been proposed. In addition, last researchs on parabolic trough have been mentioned.
