Abstract
La tecnología solar térmica es la única dentro de las renovables, junto con la
hidroeléctrica de bombeo, con capacidad de integrar almacenamiento de energía sin
necesidad de baterías electroquímicas con eficiencia probada. El continuo desarrollo de
esta tecnología, así como las mejoras en los procesos productivos de los componentes
de los que hace uso, auguran su expansión en el futuro próximo.
A lo largo de la memoria se establecerá los procesos de cálculo para el modelado básico
de los principales sistemas de una central solar térmica de canales cilindro-parabólicos,
almacenamiento térmico de 6 horas y refrigeración seca. En primer lugar, se
seleccionará la localización de la central, tomando como referencia un caso real y se
simulará mediante la herramienta informática SAM. A continuación, se ofrecerá una
metodología de cálculo de los elementos principales de la central (campo solar, bloque
de potencia y sistema de almacenamiento). El proceso de diseño finalizará con el
dimensionado del equipo para la refrigeración por aire.
Por último, se realizará una valoración económica del coste del proyecto y de la
rentabilidad de la inversión necesaria.
Concentrated solar power technology is the only renewable, along with pumped hydropower, with the ability to integrate energy storage with proven efficiency not relaying in chemical batteries. The continuous development of this technology and the improvements in the manufacturing processes of the components used, foresee its future expansion in the near future. Throughout the report, calculation methods for the basic modelling of the main systems of a parabolic-trough concentration solar plant with 6 hours thermal storage and dry cooling will be established. First, the location of the plant will be selected taking a real case as reference, being it simulated by SAM software. Next, calculation procedures for the main systems modelling (solar field, power block and storage system) will be shown. The design process will end sizing the air cooler condenser required for the refrigeration of the plant. Finally, an economic assessment will be performed, providing a value for the capital cost of the project and analyzing the profitability of the initial investment.
