EXPLICACIÓN DE LA INVENCIÓN EXPLANATION OF THE INVENTION
Así, el equipo generador de energía mediante captación solar fotovoltaica, transportable y aplicable para alimentación eléctrica de sistemas de comunicación en instalaciones remotas que la invención propone se configura como una destacable novedad dentro de su campo de aplicación, ya que a tenor de su implementación y de forma taxativa se alcanzan satisfactoriamente los objetivos anteriormente señalados como idóneos, estando los detalles caracterizadores que lo hacen posible y que lo distinguen de lo ya conocido adecuadamente recogidos en las reivindicaciones finales que acompañan a la presente descripción. Thus, the power generating equipment by means of photovoltaic, transportable and applicable solar capture for power of communication systems In remote installations that the invention proposes, it is configured as a remarkable novelty within its field of application, since according to its implementation and in a restrictive way the objectives previously indicated as suitable are satisfactorily achieved, being the characterizing details that make it possible and that distinguish it from what is already well known in the final claims that accompany the present description.
De forma concreta, pues, lo que la invención propone es un equipo generador de energía que se configura a partir de un contenedor marítimo transformado especialmente para albergar en su interior, durante el transporte del mismo, todos los elementos que conforman el equipo y, una vez instalado, servir como base de apoyo al campo de captación fotovoltaico que incorpora, ya que la energía eléctrica que genera para alimentar los sistemas de comunicaciones a que se destina es de origen solar. Specifically, then, what the invention proposes is an energy generating equipment that is configured from a maritime container specially transformed to house inside, during its transport, all the elements that make up the equipment and, a Once installed, serve as a support base for the photovoltaic collection field that it incorporates, since the electrical energy generated to power the communications systems it is intended for is of solar origin.
Para ello, y como parte electrónica de potencia, el equipo cuenta, además de con una serie de módulos fotovoltaicos para la citada captación solar, los cuales se disponen oblicuamente cubriendo el contenedor fijados sobre una estructura metálica unida solidariamente al suelo y al contenedor, con, al menos, dos cargadores de baterías, un inversor bidireccional, un rectificador, un grupo de baterías y un grupo generador diesel. For this, and as an electronic power part, the equipment also has a series of photovoltaic modules for the aforementioned solar collection, which are arranged obliquely covering the container fixed on a metal structure joined in solidarity with the ground and the container, with At least two battery chargers, a bidirectional inverter, a rectifier, a battery group and a diesel generator group.
Los módulos fotovoltaicos proporcionan del 60 al 85% de la energía necesaria para alimentar al sistema, en función de la potencia elegida, mientras que el resto es proporcionado por el grupo generador diesel . The photovoltaic modules provide 60 to 85% of the energy needed to power the system, depending on the power chosen, while the rest is provided by the generator set diesel
Los cargadores de baterías se encargan de buscar el punto de máxima potencia de los módulos fotovoltaicos; el inversor bidireccional tiene la capacidad de convertir la corriente continua en alterna y viceversa, siendo el encargado de generar la energía eléctrica, tanto en corriente continua como en corriente alterna, además, gestiona el estado de carga de las baterías y gestiona la corriente que viene del grupo generador (sólo en el caso que sea necesario el arranque del generador, por días de lluvia y mala climatología) . The battery chargers are responsible for finding the maximum power point of the photovoltaic modules; The bidirectional inverter has the ability to convert direct current into alternating current and vice versa, being in charge of generating electrical energy, both in direct current and in alternating current, in addition, it manages the state of charge of the batteries and manages the current that comes of the generator group (only in the case that it is necessary to start the generator, due to rainy days and bad weather).
Por su parte, las baterías se encargan de almacenar energía para proporcionar corriente al sistema durante las horas nocturnas, debiendo señalarse que el grupo generador sólo funciona cuando las condiciones climatológicas impiden el funcionamiento óptimo de los módulos fotovoltaicos . Así, cuando el grupo arranca (cosa que hace de forma automática) carga las baterías al nivel óptimo y también suministra la corriente necesaria para mantener estable el suministro de corriente continúa y alterna. On the other hand, the batteries are responsible for storing energy to provide power to the system during the night hours, it should be noted that the generator set only works when the weather conditions prevent the optimal operation of the photovoltaic modules. Thus, when the group starts (which it does automatically) it charges the batteries to the optimum level and also supplies the current necessary to keep the continuous and alternating current supply stable.
Por último el rectificador se encarga de estabilizar la tensión a 48V (+-1V) , que es la tensión convencional de funcionamiento de los equipos de comunicaciones. Esta tensión se puede ajustar también a 12 o 24V. Finally, the rectifier is responsible for stabilizing the voltage at 48V (+ -1V), which is the conventional operating voltage of the communications equipment. This voltage can also be set to 12 or 24V.
En cuanto a la configuración estructural del equipo, este parte, como se ha dicho, de un contenedor marítimo estándar de 20 pies, con la particularidad de que incorpora una doble puerta en la parte posterior del mismo, exactamente igual a la doble puerta ubicada en la parte delantera. As for the structural configuration of the equipment, this part, as has been said, of a standard 20-foot maritime container, with the particularity that it incorporates a double door at the back of it, exactly the same as the double door located in the front part.
Pero, además, a dicho contenedor se le ha incorporado interiormente una cámara o habitáculo de paredes aislantes, del tipo que se instala en las cámaras frigoríficas (10 cm de poliuretano encerrado entre dos láminas de acero) , contemplándose entre el contenedor y las paredes de dicho habitáculo un hueco de 7 cm, en cada cara, que ha sido cubierto por poliuretano inyectado resistente a altas temperaturas. But, in addition, to said container a chamber or interior of insulating walls has been incorporated inside, of the type that is installed in the cold stores (10 cm of polyurethane enclosed between two sheets of steel), being contemplated between the container and the walls of said cabin a 7 cm hole, on each side, which has been covered by injected polyurethane resistant to high temperatures.
El citado habitáculo aislado térmicamente, en el que se disponen los elementos funcionales del equipo convenientemente dispuestos en diferentes armarios y/o salas independientes, deja un espacio libre en el contenedor que conforma un segundo habitáculo sin aislar reservado para el grupo generador, ya que éste no necesita estar aislado del exterior. The said thermally insulated cabin, in which the functional elements of the equipment are conveniently arranged in different cabinets and / or independent rooms, leave a free space in the container that forms a second uninsulated cabin reserved for the generator group, since this It does not need to be isolated from the outside.

Finalmente hay que destacar que el equipo generador preconizado incorpora como elementos de seguridad, un sistema contraincendios, un sistema de detección de H2 y sensores magnéticos para detectar la entrada de personal al contenedor. Finally, it should be noted that the recommended generator equipment incorporates as security elements, a fire system, an H2 detection system and magnetic sensors to detect the entry of personnel to the container.
El sistema contraincendios consta de, al menos, dos detectores de incendio dispuestos uno en el habitáculo interior aislado y otro en el del grupo generador, una centralita colocada a la entrada de la sala de baterías, dos indicadores luminosos colocados en el exterior, uno en la puerta frontal y otro en la puerta trasera. The fire system consists of at least two fire detectors arranged one in the insulated interior cabin and another in the generator group, a switchboard placed at the entrance of the battery room, two light indicators placed outside, one at the front door and one at the back door.
El funcionamiento es el siguiente; en caso de activarse uno de los dos detectores de humo de cualquiera de los habitáculos, se activa el aviso de incendios y se comienzan a cerrar todas las rejillas y a apagar los equipos de climatización, el sistema avisa al sistema de control remoto de que hay un aviso de incendio y, si se activa el segundo detector de humo, se desconectan todos los equipos eléctricos salvo la centralita de incendios, y se activa el sistema de extinción de incendio mediante gas HFC-227ea en la sala de baterías y sala de inversores, y mediante agua pulverizada en la sala del generador.  The operation is as follows; in case of activating one of the two smoke detectors of any of the rooms, the fire warning is activated and all the grilles are closed and the air conditioning equipment is turned off, the system warns the remote control system that there is a fire warning and, if the second smoke detector is activated, all electrical equipment except the fire panel is switched off, and the HFC-227ea gas fire extinguishing system is activated in the battery room and inverter room, and by water spray in the generator room.
En cuanto al funcionamiento del detector de H2, el nivel de concentración de hidrógeno se monitoriza continuamente a través del sensor de hidrógeno "TS 293 PI" previsto en el equipo para evitar llegar a niveles peligrosos (> 4%) . En caso de que la concentración de hidrogeno alcance el 2% comienza la ventilación forzada para evacuar el gas de la sala de baterías. Regarding the operation of the H2 detector, the hydrogen concentration level is continuously monitored through the hydrogen sensor "TS 293 PI" provided in the equipment to avoid reaching dangerous levels (> 4%). In case the hydrogen concentration reaches 2%, forced ventilation begins to evacuate the gas from the battery room.
Si el nivel de hidrogeno es elevado, y se está evacuando al exterior mediante el sistema de ventilación, el sistema avisa con un indicador luminoso situado en el exterior del contendor, en la puerta frontal . If the hydrogen level is high, and it is being evacuated to the outside through the ventilation system, the system warns with a light indicator located outside the container, at the front door.
Se constata, pues, que las ventajas del equipo preconizado respecto a otros sistemas son destacables, ya que: Therefore, it is noted that the advantages of the recommended equipment compared to other systems are remarkable, since:
- Genera dos redes de corriente, una en corriente continua y otra en corriente alterna. Para conseguir mantener estas redes no hace más de una transformación en la alternancia de la corriente, es decir, en el peor de los casos sólo transforma una sola vez la corriente alterna en continua o la continua en alterna, a diferencia de otros sistemas en los que la corriente es transformada dos o tres veces perdiendo en cada transformación un 5% de eficiencia. - It generates two current networks, one in direct current and one in alternating current. For managing to maintain these networks does not make more than one transformation in the alternation of the current, that is, in the worst case it only transforms the alternating current into continuous or the continuous one into alternating, unlike other systems in which The current is transformed two or three times, losing 5% efficiency in each transformation.
- El equipo es portable y se puede transportar como cualquier contenedor marítimo. Es decir todo lo necesario para el funcionamiento del contenedor está dentro del propio contenedor. Incluso los módulos fotovoltaicos y la estructura necesaria para la fijación de los mismos van dentro del contenedor durante el transporte y, una vez ubicado en su emplazamiento, se sacan del interior y se instala de forma rápida. Además, el equipo generador propuesto viaja como cualquier contenedor marítimo y todos sus elementos llevan instalados soportes antisísmicos, diseñados especialmente para evitar la rotura de cualquier elemento durante su desplazamiento. - The equipment is portable and can be transported like any sea container. In other words, everything necessary for the operation of the container is inside the container itself. Even the photovoltaic modules and the structure necessary for fixing them go inside the container during transport and, once located, they are removed from the interior and installed quickly. In addition, the proposed generator set travels like any maritime container and all its elements have anti-seismic supports installed, specially designed to prevent the breakage of any element during its movement.
Los grupos de climatización han sido diseñados especialmente para esta aplicación y son capaces de funcionar incluso en las peores condiciones (45° de temperatura externa y 100% de humedad) . Además incorporan la función de "f"ree cooling" para aumentar la eficiencia energética. The air conditioning units have been specially designed for this application and are capable of operating even in the worst conditions (45 ° external temperature and 100% humidity). They also incorporate the function of "f " ree cooling "to increase energy efficiency.
- No tiene ganancias térmicas exteriores gracias al aislamiento de que dispone, a que exteriormente está pintado con pintura con un alto índice de reflexión solar y a la sombra que proyectan sobre él los módulos fotovoltaicos que se disponen cubriendo el contenedor incorporados en una estructura metálica prevista para ello. - El equipo cuenta con un sistema de control y monitorización específicos para esta aplicación que permite evaluar en cada momento el rendimiento de los módulos fotovoltaicos, conocer el estado de funcionamiento de cualquier elemento así como parametrizar a distancia (vía PC) la configuración de cualquier elemento electrónico. - It has no external thermal gains thanks to the insulation it has, because it is painted with high solar reflection paint and the shade cast by the photovoltaic modules that are arranged covering the container incorporated in a metal structure intended for it. - The equipment has a specific control and monitoring system for this application that allows you to evaluate the performance of the photovoltaic modules at any time, know the operating status of any element as well as remotely parameterize (via PC) the configuration of any element electronic.
Todas las rejillas que lleva para la ventilación son unas rejillas especiales anti arena, que, a diferencia de otros sistemas, no necesitan filtro de sustitución y evitan la entrada de arena incluso en las peores condiciones, por ejemplo si se instala en el desierto. Hay que puntualizar que las rejillas por sí solas consiguen un aislamiento IP-55 (índice de protección) , pudiendo incluso incorporar filtros con grado de protección superior. All the grilles that it carries for ventilation are special anti-sand grilles, which, unlike other systems, do not need a replacement filter and prevent the entry of sand even in the worst conditions, for example if it is installed in the desert. It should be noted that the grilles alone achieve an IP-55 insulation (protection index), and can even incorporate filters with a higher degree of protection.
Además el equipo está capacitado para detectar cuando la eficiencia de los módulos ha bajado debido a pérdidas por suciedad, para lo cual, opcionalmente, incorpora un sistema de limpieza que además actúa como elemento protector contra agentes atmosféricos y abrasivos, como podría ser una tormenta de arena en el desierto, etc., estando dotado de control automatizado mediante estación meteorológica. In addition, the equipment is capable of detecting when the efficiency of the modules has decreased due to losses due to dirt, for which, optionally, it incorporates a cleaning system that also acts as a protective element against atmospheric and abrasive agents, such as a storm of sand in the desert, etc., being equipped with automated control by means of a weather station.
