Method for distributing heliostats in tower plant

Abstract

Method for distributing heliostats in a tower solar plant surrounded by a field of heliostats which reflect solar radiation on said tower. The distribution method for said heliostats consists of imitating the systems that are found in nature to maximize the collection of light (plant seeds, leaves and petals) and which is mathematically described by Fermat spirals in a number belonging to the Fibonacci series, through the placement, in polar coordinates, of each heliostat according to a radius and an angle defined byrn=cn·n;θn=n·2·πτ2;being:rn distance from the tower (2) to the position of the heliostat n (3),θn the angle formed by the radius rn with the radius rn-1,n number of the heliostat (3) we wish to place,cn parameter that corresponds to the compactness index of the heliostats (3) in the plant,τ the irrational limit of the golden section, i.e.,τ=1+1+1+1+1+…

Description

TECHNICAL AREA OF THE INVENTION[0001]This invention is encompassed within the area of electric energy generation from solar radiation through a plant like those with a central tower receptor.[0002]The object of the invention consists of achieving optimal performance of the thermo electric plant through the selective distribution of the heliostats relative to the receptor tower.BACKGROUND OF THE INVENTION[0003]A thermo electric solar plant is an industrial facility in which, through the heating of a fluid by way of solar radiation and its use in a convectional thermo dynamic cycle, the necessary power is produced to move an alternator for the generation of electric energy in the same way as in a classic thermal plant.[0004]Constructively, it is necessary to concentrate the solar radiation in order to be able to achieve elevated temperatures, of over 300° C., and thus obtain an acceptable performance in a thermo dynamic cycle, which would not be attainable with lower temperatures.

AI Technical Summary

Benefits of technology

The invention provides a solar field system with heliostats placed in a way that minimizes optical losses caused by shadows and blockings, reduces atmospheric attenuation, and maximizes the density of heliostats in the solar field. The heliostats are placed by an optimized positioning system that increases performance and reduces construction costs. The system avoids the use of complex software and eliminates the current lines of transition and symmetry. The technical effects of the invention include higher performance, increased production, and savings in time and resources.

Problems solved by technology

All of these types of plants feature a configuration in which the heliostats are distributed as a function of the size and distance to the tower, following certain common radial dispositions from the tower and known as “corn field” and “radial staggered” Said configurations have the disadvantage that shadows and blockings are produced among the neighbouring heliostats and therefore some of them need to be eliminated in order to avoid this effect.
