Description
Dispositivo para la prevención de daños ocasionados por el viento en seguidores solares.Damage prevention device caused by wind in solar trackers.
La presente invención, según se expresa en el enunciado de esta memoria descriptiva, se refiere a un dispositivo para la prevención de daños ocasionados por el viento en seguidores solares, cuya finalidad es evidentemente la de evitar que se originen desperfectos o daños en los seguidores solares cuando se producen fuertes vientos.The present invention, as expressed in the set forth in this specification, refers to a device for the prevention of wind damage in followers solar, whose purpose is obviously to prevent cause damage or damage to solar trackers when They produce strong winds.
El dispositivo es aplicable en aquellos sistemas en los que el movimiento del seguidor solar se realiza mediante elementos hidráulicos, por lo que el objeto de la invención no es otro que el de actuar sobre dichos elementos hidráulicos para producir la activación de éstos en caso de fuertes vientos y dispongan el seguidor solar en horizontal, a fin de conseguir que la incidencia del viento sea mínima.The device is applicable in those systems in which the movement of the solar tracker is done by hydraulic elements, so that the object of the invention is not other than acting on said hydraulic elements to produce their activation in case of strong winds and arrange the solar tracker horizontally, in order to get the incidence of wind is minimal.
Actualmente, la tendencia en las instalaciones de energía fotovoltáica, de forma cada vez más frecuente, es colocar los paneles en seguidores solares en lugar de llevar a cabo el montaje en instalaciones fijas orientada al sol. Como sea que la potencia de éstas es en principio proporcional al coseno del ángulo formado por la perpendicular a la superficie del panel y a la dirección panel-sol, los seguidores al orientar hacia el sol consiguen en cada momento la máxima potencia aprovechable.Currently, the trend in facilities of photovoltaic energy, more and more frequently, is place the panels on solar trackers instead of carrying out installation in fixed installations oriented to the sun. However the power of these is in principle proportional to the cosine of the angle formed by the perpendicular to the surface of the panel and the panel-sun direction, followers when targeting towards the sun they get maximum power at all times usable
Para prevenir los efectos de vientos fuerte o incluso huracanados se hace necesario colocar anemómetros, de forma que cuando el viento supera una velocidad de seguridad se pone en marcha una acción de emergencia en el sistema de movimiento del seguidor, que actúa sobre el mismo de forma que los paneles queden en posición horizontal, pues cerca del suelo la dirección del viento es sensiblemente también horizontal y de esta forma la resistencia al viento es la menor posible, evitando así posibles daños o la rotura de determinadas partes o elementos de la instalación.To prevent the effects of strong winds or even hurricanes it is necessary to place anemometers, so that when the wind exceeds a safety speed it is set to marches an emergency action in the movement system of the follower, which acts on it so that the panels are in a horizontal position, because the direction of the wind is also substantially horizontal and in this way the wind resistance is the least possible, thus avoiding possible damage or breakage of certain parts or elements of the installation.
Pues bien, aunque los sistemas referidos y basados en el concepto referido con anterioridad, resultan eficaces funcionalmente, sin embargo presentan una serie de inconvenientes que pueden resumirse en los siguientes:Well, although the referred systems and based on the concept referred to above, they are effective functionally, however they present a series of drawbacks which can be summarized in the following:
- --
- No es posible realizar cálculos aerodinámicos exactos, ya que las formas del seguidor no se parecen en nada a perfiles normalizados, así como que los datos que obtuviesen de un ensayo en túnel aerodinámico diferirían de las condiciones en campo, donde es imposible simular las turbulencias de la orografía de cada campo en concreto. En todo caso, los cálculos son siempre orientativos y obligan a reducir la velocidad de emergencia, con el consiguiente perjuicio energético.It is not possible to perform accurate aerodynamic calculations, since the forms of the follower do not resemble standard profiles at all, so like the data they got from a tunnel test aerodynamics would differ from field conditions where it is impossible to simulate the turbulence of the orography of each field in concrete. In any case, the calculations are always indicative and force to reduce the emergency speed, with the consequent energy damage
- --
- En aquellos casos en que la dirección del viento sea paralela a los paneles solares, el sistema se pondrá en horizontal aunque ello no sea necesario, reduciendo el rendimiento energético.In those cases in which the wind direction is parallel to the solar panels, the system will be horizontal although it does not as necessary, reducing energy efficiency.
- --
- Incluso en el caso de instalar un anemómetro por seguidor solar, existe el riesgo de torbellinos verticales producidos por diferencias térmicas, que de atacar a la superficie del seguidor en uno de sus extremos puede no ser detectado por el anemómetro, lo que produciría un par o torsión grande por carga simétrica que daría lugar a serios desperfectos en el seguidor solar.Even in the case of installing a anemometer by solar tracker, there is a risk of whirlpools verticals produced by thermal differences, which attack the follower surface at one end may not be detected by the anemometer, which would produce a torque or torque large by symmetrical load that would lead to serious damage in The solar tracker.
El dispositivo de la invención, aplicable en aquellos sistemas hidráulicos utilizados para producir el movimiento de seguidores solares, presenta una serie de particularidades que permiten solventar los problemas e inconvenientes referidos en el apartado anterior.The device of the invention, applicable in those hydraulic systems used to produce the solar tracker movement, presents a series of particularities that allow to solve the problems and inconveniences referred to in the previous section.
En tal sentido, el dispositivo en cuestión se constituye mediante uno o más presostatos instalados de forma adecuada, los cuales en virtud de la relación concreta que existe entre la presión y el esfuerzo, proporcionan una señal que indicará el momento exacto en que el seguidor solar se tiene que situar horizontalmente, para que ofrezca una mínima resistencia al viento y se evite con ello posibles daños o roturas de la instalación que pudieran producirse por los efectos del viento fuerte y/o huracanado.In that sense, the device in question will constitutes by one or more pressure switches installed in a way adequate, which by virtue of the concrete relationship that exists between pressure and effort, they provide a signal that will indicate the exact moment when the solar tracker has to be located horizontally, to offer minimal wind resistance and thus avoid possible damage or breakage of the installation that could be caused by the effects of strong wind and / or hurricane
El presostato o presostatos, como es evidente, irán conectados al sistema hidráulico correspondiente con el fin de detectar el aumento de presión y actuar en consecuencia, enviando una señal u orden al mecanismo productor del movimiento para que éste actúe y disponga el seguidor solar en posición horizontal.The pressure switch or pressure switches, as is evident, will be connected to the corresponding hydraulic system in order to detect the increase in pressure and act accordingly, sending a signal or order to the movement producing mechanism so that it acts and puts the solar tracker in position horizontal.
Mediante el dispositivo de la invención se consigue que ante eventualidades como las referidas con anterioridad, el sistema se ponga en posición horizontal cuando se llega a una fuerza real establecida como la de seguridad, de acuerdo con el cálculo correspondiente de la estructura, y no de una forma estimada como sería en el caso de utilizar anemómetros para la misma finalidad.By means of the device of the invention, get that in case of eventualities like those referred to previously, the system will be placed horizontally when comes to a real force established as security, of according to the corresponding calculation of the structure, and not of an estimated way as it would be in the case of using anemometers for the same purpose.
Asimismo, en base al dispositivo de la invención el sistema mantendrá su posición de seguimiento al sol, aún en casos de velocidades altas del viento cuando éste sople en direcciones paralelas a las placas solares, con el consiguiente aumento de rendimiento energético.Also, based on the device of the invention the system will maintain its position of tracking in the sun, even in cases of high wind speeds when it blows in directions parallel to the solar panels, with the consequent Increase in energy efficiency.
Igualmente, en base al dispositivo referido el sistema generará una señal de emergencia que preservará la seguridad del mismo, aún en caso de torbellinos verticales y en cuanto éstos afecten a una superficie parcial.Likewise, based on the device referred to system will generate an emergency signal that will preserve the safety of the same, even in case of vertical whirlpools and in how much they affect a partial surface.
En base al dispositivo referido se consigue una serie de ventajas entre las que pueden destacarse las siguientes:Based on the referred device, a series of advantages among which the following:
1°) Ahorro económico ya que el coste de un presostato es inferior al de un anemómetro.1st) Economic savings since the cost of a Pressure switch is lower than an anemometer.
2°) Mayor vida útil del sistema, al no existir partes móviles que giran constantemente siempre que exista viento.2nd) Longer system life, as it does not exist moving parts that rotate constantly whenever there is wind.
3°) Mayor fiabilidad.3rd) Greater reliability.
