Abstract
En la actualidad, en numerosas centrales de receptor central de torre, en la época del año en la que el campo solar recibe la mayor cantidad de radiación y se alcanza con facilidad la potencia térmica neta del receptor, se opta por desorientar los heliostatos más alejados de la torre con el fin de evitar posibles daños en los equipos de la instalación. De este modo, no toda la radiación recibida por los heliostatos es aprovechada para generar energía eléctrica. Con el fin de poder aprovechar toda la energía recibida por los heliostatos, en este proyecto se detalla la programación de un algoritmo matemático que permite simular una central de concentración de energía solar con dos receptores ofreciendo una alternativa a las centrales con almacenamiento térmico de un sólo receptor.
Para evitar que parte de la energía recibida por los heliostatos sea desaprovechada, en este proyecto se ha decidido colocar un segundo receptor, justo debajo del receptor principal, para reflejar sobre este toda la radiación reflejada por los heliostatos que, en caso de no instalarse este nuevo receptor, sería desaprovechada. Siendo los meses en los que más energía solar recibe el campo de heliostatos los meses más calurosos del año, con esta alternativa se puede aprovechar esta energía para enfriar agua a través de una máquina de absorción y alimentar una red de district cooling para la climatización de viviendas cercanas a la instalación.
En este proyecto, se ha simulado la central solar de Gemasolar para mostrar que este sistema con dos receptores puede ser una alternativa para aquellas centrales en las que se desea aprovechar toda la radiación recibida.
At present, in numerous solar tower power plants, in the epoch of the year in which the solar field receives the major quantity of radiation and there is reached by facility the thermal clear power of the receiver, one chooses to disorient the heliostats most removed from the tower in order to avoid possible hurts in the equipments of the installation. Thus, not the whole radiation received by the heliostats is taken advantage to generate electric power. In order to be able to take advantage of this energy received by the heliostats, in this project there is detailed the programming of a mathematical algorithm that allows to simulate a solar tower power plant with two receivers offering an alternative to the head offices with thermal storage and only one receiver. To prevent that part of the energy received by the heliostats is missed, in this project it has been decided to place the second receiver, just below the principal receiver, to reflect on this one the whole radiation reflected by the heliostats that, in case of not installing this new receiver, it would be missed. Being the months in which more solar power receives the solar field the warmest months of the year, with this alternative it is possible to take advantage of this energy to cool water across a machine of absorption and feed a district cooling network for the air conditioning of housings near to the installation. In this project, Gemasolar solar power station has been simulated to show that this system with two receivers can be an alternative for those plants in which the whole received radiation is wanted to take advantage.
