Definitions
- the present invention is included within the sector of electric power generation from solar radiation by means of a plant of the type of central tower receiver.
- the object of the invention is to achieve optimum performance of the thermoelectric plant by selective distribution of heliostats with respect to the receiving tower.
- thermoelectric solar plant is an industrial installation in which, from the heating of a fluid by means of solar radiation and its use in a conventional thermodynamic cycle, the necessary power is produced to move an alternator for electric power generation as in a thermal power plant classic
- a tower plant - also known as a central receiver system - is composed of a concentrator system or heliostat field, which captures and concentrates the direct component of solar radiation on a receiver - where the conversion of radiant energy into energy occurs thermal— that is usually installed on top of a tower.
- the working fluid can be, among others, air, water vapor, molten sodium or molten salts, according to the chosen technology. In water vapor, it directly moves a turbine. In the others, the fluid transports the heat to a steam generator, with which a turbine that moves the electric generator is operated.
- the object of the invention is the application of the arrangement of the leaves, stems and seeds of the plants to the specific distribution of heliostats in the solar field. This provision is called phyloxis and is characteristic of each plant species. Its function is that these leaves, stems and seeds are exposed to the sun with the minimum possible interference by their partners maximizing the capture of light.
- This specific distribution allows the heliostats to be placed in such a way that the optical losses caused by shadows and blockages between neighboring heliostats, atmospheric attenuation and increased interception caused by large distances between heliostats and the tower are minimized, thus optimizing the use of solar radiation to maximize the density of heliostats in the solar field.
- the golden section or "divine proportion" results from the division of a linear quantity (magnitude of distance, duration, etc., abstract by the length of a segment) so that the relationship between the total length and the longest part is identical to that between the longest and the shortest part.
- the arrangement of the different elements or heliostats of a plant is described by a regularity in the divergence of the angle formed by the successive arranged elements. This angle divides a complete circle into a fraction that coincides with the Fibonacci series numbers (1/2, 1/3, 2/5, 3/8, 5/13 ...) that converge to the irrational limit of the Golden section 0.382 ..., corresponding to the angle of 137.5 ... degrees.
- n e N natural number that corresponds to the heliostat number that we want to place in a certain area.
- ⁇ is the irrational limit of the golden section 0.382 ..., corresponding to the angle of 137.5 ... degrees. Being the irrational limit of the golden section:
- ⁇ C n is a parameter that corresponds to the index of compactness of heliostats in the solar field. This parameter can be constant for all heliostats or be different for each one of them, optimizing the field based on the following variables:
- o L e [-] corresponds to the latitude at which the solar field will be located.
- ⁇ ⁇ e [0.2TT] corresponds to the location angle of each heliostat.
- thermoelectric plant configured through this arrangement of heliostats allows:
- system object of the invention eliminates the presence of current transition lines and, if desired, eliminates symmetry, both present in thermoelectric plants that are in operation today.
- Figure 1. Shows the state of the art, "radial staggered” (three bobbin) and "corn field” distributions.
- Figure 2 - Shows a scheme of the distribution of heliostats resulting from the system object of the invention.
- Figure 3. Shows a scheme of the distribution of the elements of the plant object of the invention.
- Figure 1 shows the distribution of heliostats according to the configurations used so far: “radial staggered” and “corn field”.
- Figure 2 shows how the heliostat field would look if it is distributed following the method of the invention.
- FIG 3 shows a thermoelectric plant (1) located in a certain location with latitude "L", in which a receiver tower (2) of a certain height "h” is erected to which the solar rays (4) will reach a once reflected by heliostats (3) that are arranged around said receiving tower (2).
- the generation of electrical energy is given by the incidence of solar rays (4) reflected in said receiving tower (2) where they are concentrated, heating a heat transfer fluid that will be used to move a turbine and generate electrical energy.
- thermoelectric plant (1) has a number "n N " of heliostats determined by the capacity or needs of the plant.
- each of the "n" heliostats (3, 3 ', 3 ") is performed according to a radius r n (r 3 , r 3 >, r 3 ) , which corresponds to the line that joins the heliostat (3, 3 ', 3 ") to the tower (2) and according to an angle ⁇ ⁇ ( ⁇ , ⁇ ,, ⁇ ⁇ ) corresponding to the angle formed by the radius r n with the radius r n- i.
- c n can be a constant for all heliostats or can be varied for each of them.
- c n we obtain a field distribution of the heliostats (3) whose plan view of the heliostats (3) of the thermoelectric plant (1) results in an identical scheme to the one that follows the distribution found, by example in composite flowers and set of seeds, the most famous example being the distribution of the seeds in a sunflower, as shown in figure 2. This arrangement is described mathematically by parabolic or Fermat spirals in a number belonging to the Fibonacci series.
