Description

PLANTA OFFSHORE DE CONVERSiÓN DE ENERGíAS EÓLICA Y UNDIMOTRIZ A ELÉCTRICA CAMPO TÉCNICO DE LA INVENCiÓN 5 La presente invención pertenece al campo técnico de la conversión de las energías eólica y undimotriz (energía procedente de las olas oceánicas) a energía eléctrica en instalaciones flotantes a modo de plataformas flotantes ubicadas en el mar. OBJETIVO DE LA INVENCiÓN 10 El objetivo de la presente invención denominada PLANTA OFFSHORE DE CONVERSiÓN DE ENERGíAS EÓLICA Y UNDIMOTRIZ A ELÉCTRICA, es la conversión altamente eficiente de las energías eólica y undimotriz a energía eléctrica en base al aprovechamiento de la estructura flotante que hace de soporte tanto del generador eólico como de las instalaciones de conversión de energía undimotriz. 15 ANTECEDENTES DE LA INVENCiÓN En el estado actual de la técnica aplicada a la producción energía eléctrica mediante energía procedente de las olas oceánicas existe desde hace décadas gran variedad de modelos, dada la sencillez constructiva de estos dispositivos. 20 La energía transportada por las olas oceánicas depende de la altura y la frecuencia. Por tanto en aguas profundas en las cuales la profundidad sobrepasa la mitad de la longitud de onda, el flujo de energía definido como potencia viene dado como p = p' g2 . Hmo . T /(64 ·n) ~ 0.5· Hmo . T siendo 25 P, el flujo de energía o potencia la densidad del agua (kg/m3) 30 P, g, la aceleración de la gravedad (m/s2) Hmo, la altura significativa de la ola (m) T, es el período de la ola (s). La potencia específica (potencia por unidad de frente de ola) neta aportada a la red está dada como P =r¡ ·0.5· Hmo ·T (kW/m) donde 1] es la eficiencia total de conversión. Así, en el caso de oleaje oceánico cuya altura significativa de ola sea de 4 m, con una frecuencia de 7 s bajo una eficiencia de conversión del 50%, la energía proporcionada a red sería aproximadamente P = 1] ·0.5· Hmo . T ~ 0.5 x 0.5 x 42 x 7 = 28 kW/m. Esto 5 supone unos 28 kW por metro de frente de ola, equivalente a 2800 kW por cada 100 metros de longitud de plataforma, lo cual significa una potencia considerable. Entre los documentos de patente de máquinas de conversión de energía undimotriz en energía eléctrica se conoce la solicitud de patente W02010058047-A1 denominada "Dispositivo de transformación de energía undimotriz en energía eléctrica" consiste en 10 un dispositivo de transformación de energía undimotriz en energía eléctrica caracterizado por estar constituido esencialmente por un campo de boyas que son las que por el movimiento de las olas facilitan a un conjunto de ejes y engranajes esta fuerza que se transforma en movimiento notorio de ejes que impulsan los generadores de energía eléctrica. 15 Asimismo, actualmente se conocen diversas estructuras de artefactos marinos que constituyen el soporte de generadores eólicos convencionales ubicados en campos de explotación de vientos oceánicos para la conversión de energía eólica a eléctrica, los cuales en general llevan cerca de un par de décadas en operación con alta eficiencia partiendo de que la calidad del viento es mas alta que en zonas montañosas. 20 La estimación de la potencia de energía eólica susceptible de conversión idealmente se obtiene partiendo de que toda masa de aire m con movimiento uniforme unidireccional a velocidad v va asociada a una energía cinética que definida como E = 0.5 m V = 0.5 Vol. Pa V Siendo Pa es la densidad del aire de la corriente uniforme y Vol. el volumen de la masa 25 m, la energía por unidad de volumen resulta ser: 30 e= 0.5 Pa V entonces, al ser el caudal volumétrico Q a través de una superficie de control estacionaria de sección frontal A igual al producto de la sección transversal o normal a la dirección del viento por la velocidad del mismo v, se tiene: Q =A v resultando que el flujo de energía o potencia eólica de la corriente de viento a través de A vale: P = e Q = 0.5 Pa A V 5 La expresión que define la potencia prueba que existe una alta dependencia de la potencia con la velocidad de orden exponencial al cubo. Del mismo modo permite deducir que operando a nivel del mar, donde la densidad del aire es máxima, con un valor medio de 1,225 kg/m3, se obtienen los mejores resultados. No obstante, en el estado actual de la técnica relacionada con la conversión de energía eólica procedente de los vientos marinos así como la energía undimotriz procedente del oleaje oceánico, no se conocen artefactos flotantes marinos (offshore) habilitados para soportar y operar simultáneamente los dos tipos de generadores 10 (eólicos y undimotrices) en un solo artefacto marino de soporte. BREVE DESCRIPCiÓN DE LA INVENCiÓN La PLANTA OFFSHORE DE CONVERSiÓN DE ENERGíAS EÓLICA Y UNDIMOTRIZ A ELÉCTRICA consiste en una instalación marina capaz de soportar un generador eólico y un generador undimotriz. Tal instalación marina puede estar diseñada para 5 operar a flote y anclada al lecho marino, cuando opera en aguas profundas (mayor de 100 metros) o estar diseñadas para operar cerca de la costa en donde la profundidad (menor de 100 metros) permite artefactos cuya estructura (no es flotante) y se halla pilotada y empotrada en el lecho marino. En cada uno de ambos tipos de soporte se hallan la instalación eólica de generación y la instalación undimotriz de generación, 10 ambas constituidas por tecnologías convencionales.

OBJECTIVE OF THE INVENTION 10 The objective of the present invention called OFFSHORE PLANT OF CONVERSION OF WIND ENERGIES AND UNDIMOTRIZ TO ELECTRICAL, is the highly efficient conversion of wind and wave energy to electrical energy based on the use of the floating structure that supports from both the wind generator and the wind power conversion facilities. 15 BACKGROUND OF THE INVENTION In the current state of the art applied to the production of electrical energy by means of energy from ocean waves, there have been decades of great variety of models, given the constructive simplicity of these devices. 20 The energy transported by ocean waves depends on height and frequency. Therefore, in deep waters in which the depth exceeds half the wavelength, the energy flow defined as power is given as p = p 'g2. Hmo T / (64 · n) ~ 0.5 · Hmo. T being 25 P, the energy flow or power density of water (kg / m3) 30 P, g, the acceleration of gravity (m / s2) Hmo, the significant height of the wave (m) T, is the period of the wave (s). The specific power (power per unit of wavefront) contributed to the network is given as P = r¡ · 0.5 · Hmo · T (kW / m) where 1] is the total conversion efficiency. Thus, in the case of ocean waves whose significant wave height is 4 m, with a frequency of 7 s under a conversion efficiency of 50%, the energy provided to the grid would be approximately P = 1] · 0.5 · Hmo. T ~ 0.5 x 0.5 x 42 x 7 = 28 kW / m. This means about 28 kW per meter of wavefront, equivalent to 2800 kW per 100 meters of platform length, which means considerable power. Among the patent documents of converters of wave energy in electric energy is known the patent application W02010058047-A1 called "Device for the transformation of wave energy into electric energy" consists of a device for transforming wave energy into electrical energy characterized Being essentially constituted by a field of buoys that are the ones that by the movement of the waves provide a set of axes and gears with this force that is transformed into a notorious movement of axes that drive electric power generators. 15 Likewise, various marine artifact structures are currently known that constitute the support of conventional wind generators located in ocean wind exploitation fields for the conversion of wind to electrical energy, which in general have been in operation for about a couple of decades with high efficiency on the basis that the wind quality is higher than in mountainous areas. 20 The estimation of the power of wind energy capable of conversion is ideally obtained on the basis that every mass of air m with uniform unidirectional movement at speed v is associated with a kinetic energy that defined as E = 0.5 m V = 0.5 Vol. Being Pa is the density of the air of the uniform current and Vol. The volume of the mass 25 m, the energy per unit of volume turns out to be: 30 e = 0.5 Pa V then, being the volumetric flow rate Q through a surface of stationary control of frontal section A equal to the product of the cross section or normal to the direction of the wind by the speed of the same v, it is had: Q = A v resulting that the flow of wind power or wind power to through A vale: P = e Q = 0.5 Pa AV 5 The expression that defines the power proves that there is a high dependence on the power with the exponential speed of the cube. In the same way it allows to deduce that operating at sea level, where the air density is maximum, with an average value of 1,225 kg / m3, the best results are obtained. However, in the current state of the art related to the conversion of wind energy from marine winds as well as wave energy from ocean waves, there are no known offshore floating marine artifacts enabled to simultaneously support and operate the two types of 10 generators (wind and wave) in a single marine support device. BRIEF DESCRIPTION OF THE INVENTION The OFFSHORE PLANT FOR CONVERSION OF WIND ENERGIES AND UNDIMOTRIZ A ELECTRICAL consists of a marine installation capable of supporting a wind generator and a wave generator. Such a marine installation may be designed to operate afloat and anchored to the seabed, when operating in deep water (greater than 100 meters) or be designed to operate near the coast where the depth (less than 100 meters) allows artifacts whose structure (not floating) and is piloted and embedded in the seabed. In each of both types of support are the wind power generation plant and the wave wind turbine installation, 10 both consisting of conventional technologies.
