Abstract
Description
Die Erfindung betrifft eine Offshore-Windenergieanlage mit einer Rotoreinheit, einem Generator und ggf. einem Getriebe.The invention relates to an offshore wind turbine with a rotor unit, a generator and possibly one Transmission.
Windenergieanlagen wandeln durch den Rotor die translato rische Energie der Luftströmung in rotatorische Energie des Triebstranges um. Bei modernen Windenergieanlagen wird diese mechanische Energie in elektrische Energie um geformt. Für diese Wandlung sind Generatorsysteme erforderlich, die entweder direkt vom Rotor der Windturbine oder mit einem zwischengeschalteten Getriebe angetrieben werden. Beide Generatorsysteme unterscheiden sich im we sentlichen durch ihre Baugröße, die sich aus der Leistung und den Antriebsdrehzahlen ergibt. Generatoren in der Me gawattklasse, die direkt vom Rotor angetrieben werden, rotieren mit einer Drehzahl von ca. 10 bis 20 min-1. Ge nertoren von Windenergieanlagen, bei denen ein hochüber setzendes Getriebe zwischen Rotor und Generator gekoppelt ist, werden mit ca. 800 bis 1800 min-1 betrieben. Diese Energiewandlung in eine Energieform mit einer höheren Wertigkeit ist mit Wirkungsgradverlusten verbunden, die in Form von Wärme anfallen. Die Verlustwärme fällt also entweder nur im Generator oder im Getriebe und im Gener tor an und muß zur Vermeidung einer Überhitzung und einer dadurch verursachten Beschädigung der Anlagenkomponenten an die Umwelt abgeführt werden.Wind turbines convert the translatory energy of the air flow into rotational energy of the drive train through the rotor. In modern wind turbines, this mechanical energy is converted into electrical energy. For this conversion, generator systems are required, which are either driven directly by the rotor of the wind turbine or with an intermediate gear. Both generator systems differ essentially in their size, which results from the power and the drive speeds. Generators in the megawatt class that are driven directly by the rotor rotate at a speed of approx. 10 to 20 min -1 . Wind turbine generators, in which a high-speed transmission is coupled between the rotor and generator, are operated at approx. 800 to 1800 min -1 . This energy conversion into an energy form with a higher value is associated with efficiency losses that arise in the form of heat. The heat loss occurs either only in the generator or in the gearbox and in the generator and must be dissipated to the environment to avoid overheating and damage to the system components.
Bei Anlagen nach dem Stand der Technik wird diese Ver lustwärme entweder durch eine direkte Durchlüftung der Gondel mit Außenluft oder durch einen Zwischenkreis mit Wärmetauscher abgeführt, wobei in jedem Fall Außenluft direkt durch die Gondel geleitet wird.In systems according to the state of the art, this Ver lust heat either by direct ventilation of the Gondola with outside air or through an intermediate circuit Heat exchanger removed, with outside air in any case is led directly through the gondola.
Für Offshore-Anlagen ist diese Durchlüftung der Gondel mit ungefilterter Außenluft nicht akzeptabel, da die kor rosive, salzhaltige Luft die Anlagenkomponenten nachhal tig schädigen und einen Ausfall bewirken kann.For offshore systems, this is the ventilation of the nacelle with unfiltered outside air not acceptable because the cor rosive, salty air the system components afterwards damage and cause failure.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Offshore-Windenergieanlage zu schaffen, bei der für eine ausreichende Kühlung des Generators und ggf. des Getrie bes gesorgt ist, ohne daß diese mit der aggressiven Au ßenluft in Kontakt kommen. The invention is therefore based on the object To create offshore wind turbine at which for a sufficient cooling of the generator and, if necessary, the gearbox bes is concerned without this with the aggressive Au outside air come into contact.
Erfindungsgemäß wird diese Aufgabe gelöst durch ein Wär metauschersystem bestehend aus einer im Bereich des Gene rators und ggf. des Getriebes angeordnete Wärmeaufnahme einheit, einer im Bereich des Turms angeordnete Wärmeab gabeeinheit, einer die beiden Einheiten miteinander ver bindenden Leitungssystem bestehend aus einer Vorlauflei tung und einer Rücklaufleitung und einer Umwälzpumpe.According to the invention, this object is achieved by a heat Exchange system consisting of a gene rators and possibly the transmission arranged heat absorption unit, a heat in the area of the tower unit, one ver the two units together binding pipe system consisting of a flow line device and a return line and a circulation pump.
Ein bevorzugtes Ausführungsbeispiel zeichnet sich dadurch aus, daß die Wärmeabgabeeinheit als um den Mantel des Turms herum verlaufende Rohrspirale ausgebildet ist. Alternativ kann die Wärmeabgabeeinheit zwischen den Wan dungen eines doppelwandig ausgebildeten Turms eingebracht sein.A preferred embodiment is characterized by this from that the heat dissipation unit than around the jacket of the Pipe spiral running around the tower is formed. Alternatively, the heat dissipation unit between the panes of a double-walled tower his.
Die Wärmeabgabeeinheit kann im oberen Bereich des Turms von der Umgebungsluft beaufschlagt angeordnet sein, vor zugsweise ist die Wärmeabgabeeinheit jedoch im unteren Bereich des Turms von dem Umgebungswasser beaufschlagt angeordnet.The heat emission unit can be in the upper area of the tower be loaded by the ambient air before however, the heat emission unit is preferably in the lower one Area of the tower affected by the ambient water arranged.
Das Leitungssystem sollte mit Drehdurchführungen versehen sein, die die Übergabe des zu fördernden Kühlmediums von der relativ zu dem Turm drehbaren Gondel auf das Lei tungssystem ermöglicht. Es können stattdessen auch flexi ble Leitungen verwendet werden, die einigen wenigen Um drehungen der Gondel relativ zu dem Turm folgen können.The pipe system should be provided with rotating unions be the handover of the cooling medium to be pumped by the gondola rotatable relative to the tower on the lei system enables. Instead, flexi ble lines are used, the few um rotations of the gondola can follow relative to the tower.
Die Wärme wird durch geeignete Transfermedien von dem Ort der Entstehung gezielt an einen anderen Ort der Wärme übertragung geleitet. Im Generator ist dieses Transferme dium üblicher Weise Luft, im Getriebe ist es Öl. The heat is removed from the place by suitable transfer media the creation targeted to another place of warmth transmission directed. This is in the generator dium is usually air, in the gearbox it is oil.
Die darin enthaltene Wärmemenge kann dann über Wärmetau scher an ein zentrales Wärmeleitungssystem übertragen werden. Dieses Wärmeleitungssystem kann als Medium z. B. frostgeschütztes Wasser verwenden.The amount of heat contained in it can then via heat dew to a central heat conduction system become. This heat conduction system can be used as a medium, for. B. use frost-protected water.
Dieses zentrale Wärmeübertragungssystem ist an einen Wär metauscher angeschlossen, der in der Turmwand der Anlage oder dem Gründungsteil der Offshore-Windenergieanlage an geordnet ist.This central heat transfer system is connected to a heat Metauscher connected in the tower wall of the plant or the founding part of the offshore wind turbine is ordered.
Für die Übertragung der Verlustwärme von der Gondel der Anlage, die das Getriebe und den Generator enthält, auf den Turm ist zwischen den Rohrleitungen eine Drehdurch führung oder ein flexibles Schlauchsystem erforderlich, um die notwendige Drehung der Gondel zu ermöglichen.For the transfer of heat loss from the nacelle System containing the gearbox and the generator the tower is rotating between the pipes guidance or a flexible hose system required, to allow the necessary rotation of the gondola.
Bei der Anordnung in der Turmwand wird die Wärmemenge über die Außenwand des Turmes an die Außenluft abgegeben. Dieses hat den Vorteil der kurzen Leitungswege aber den Nachteil der relativ großen Wärmetauscherflächen. Bei der Anordnung in dem Gründungsteil der Anlage wird die Wärme menge über die Außenwandung an das umgebende Meerwasser überführt. Dieses hat den Vorteil einer kleineren Wärme tauschergröße aufgrund des besseren Wärmeüberganges zum Wasser, aber den Nachteil der längeren Leitungswege.When placed in the tower wall, the amount of heat released to the outside air via the outer wall of the tower. This has the advantage of short cable routes Disadvantage of the relatively large heat exchanger surfaces. In the Arrangement in the founding part of the plant is the heat quantity over the outer wall to the surrounding sea water transferred. This has the advantage of a smaller heat exchanger size due to the better heat transfer to the Water, but the disadvantage of longer conduits.
Der Großteil der gesamten Verlustwärmemenge, die von dem Transfermedium transportiert wird, kann auf diese Weise in die Umwelt abgeführt werden. Der geringe Teil der Ver lustwärme, der an die Oberfläche der energieverlustbehaf teten Komponenten gelangt, muß über direkte Konvektion abgeführt werden. Ideal ist daher eine Kombination von direkter Wärmeabfuhr über Wärmetauscher, wie oben be schrieben, und eine Restwärmeabfuhr von den Komponenten oberflächen durch gereinigte Luftzufuhr in den Gondelraum unter Überdruck, so daß der Luftstrom ausschließlich nach außen gerichtet ist.The majority of the total heat loss from that Transfer medium can be transported in this way be discharged into the environment. The small part of ver Lust heat that is on the surface of the energy loss components, must be via direct convection be dissipated. A combination of is therefore ideal direct heat dissipation via heat exchanger, as above wrote, and a residual heat dissipation from the components surfaces through cleaned air supply into the nacelle area under pressure, so that the air flow only after is directed outside.

Die Figuren verdeutlichen, daß das Wärmetauschersystem aus einer Wärmeaufnahmeeinheit 16 und einer Wärmeabgabe einheit 18 besteht. Die Wärmeaufnahmeeinheit 16 ist dabei dem Getriebe 12 und dem Generator 14 zugeordnet und nimmt den wesentlichen Teil der von diesen abgegebenen Verlust wärme auf. Über ein aus einer Vorlaufleitung 20 und einer Rücklaufleitung 22 bestehendes Leitungssystem wird die Wärme zu der Wärmeabgabeeinheit 18 geführt.The figures illustrate that the heat exchanger system consists of a heat absorption unit 16 and a heat emission unit 18 . The heat absorption unit 16 is assigned to the gear 12 and the generator 14 and absorbs the essential part of the heat given off by these. The heat is conducted to the heat emission unit 18 via a line system consisting of a feed line 20 and a return line 22 .
Bei dem in Fig. 1 dargestellten Ausführungsbeispiel ist die Wärmeabgabeeinheit 18 als um den Mantel des Turms 24 herum verlaufende Rohrspirale ausgebildet, bei dem in Fig. 1b gezeigten Ausführungsbeispiel ist der Turm 24 in seinem oberen Bereich doppelwandig ausgebildet, wobei der Raum zwischen den beiden Wandungen die Wärmeabgabeeinheit 18 bildet.In the example shown in Fig. 1, the heat dissipation unit 18 is formed as to the jacket of the tower 24 around extending spiral tube, in the example shown in Fig. 1b embodiment, the tower is of double-walled at its upper portion 24, wherein the space between the two walls forms the heat emission unit 18 .

Bei dem in den Fig. 2a, 2b dargestellten Ausführungs beispielen ist die Wärmeabgabeeinheit 16 im unteren Bereich des Turms oder des Gründungsteils von dem Umge bungswasser beaufschlagt angeordnet, bei dem in Fig. 2a dargestellten Ausführungsbeispiel ist die Wärmeabgabeein heit 18 wiederum als Rohrspirale, bei dem in Fig. 2b dar gestellten Ausführungsbeispiel durch eine doppelwandige Ausbildung des Turms 24 oder des Gründungsteils ausgebil det wird. Bei diesem Ausführungsbeispiel wird die Wärme abgabe 18 von dem Umgebungswasser umspült, die Verlust wärme also von dem Umgebungswasser abgeführt. Dieses Aus führungsbeispiel hat weiter den Vorteil, daß es bei einem Betrieb der Anlage den Bereich um den Turm herum eisfrei hält.Examples In the example shown in FIGS. 2a, 2b execution the heat dissipation unit 16 is disposed applied bung water in the lower section of the tower or the foundation part of the Conversely, in the illustrated in Fig. 2a embodiment, the Wärmeabgabeein is standardized 18 again as a spiral tube, wherein in Fig. 2b illustrated embodiment is ausgebil det by a double-walled design of the tower 24 or the foundation part. In this embodiment, the heat output 18 is washed by the ambient water, so the heat loss is dissipated from the ambient water. This exemplary embodiment also has the advantage that it keeps the area around the tower free of ice when the system is in operation.
Bei dem in Fig. 3 dargestellten Ausführungsbeispiel ist der Wärmetauscher wiederum als Rohrspirale ausgebildet, die aus einem geeigneten korrosionsbeständigen Material gefertigt ist und außerhalb des Turmes angeordnet ist, so daß die Wärmeabgabeeinheit 18 von dem umgebenen Wasser unmittelbar umspült wird. Diese Ausführungsform hat den Vorteil, daß der Wärmetauscher relativ klein ausgebildet werden kann.In the embodiment shown in Fig. 3, the heat exchanger is again designed as a spiral tube, which is made of a suitable corrosion-resistant material and is arranged outside the tower, so that the heat emitting unit 18 is immediately washed by the surrounding water. This embodiment has the advantage that the heat exchanger can be made relatively small.
