The power plant (10) has a tower (12) supporting a relatively rotatable machine housing (14), provided with a wind turbine rotor which rotates about a horizontal axis and a helicopter landing platform (28). The electrical operating components of the power plant, e.g. the switchgear and transformer, are housed in a container (32) mounted at the side of the machine housing.

Description

Die Erfindung betrifft eine Windkraftanlage, die sich insbesondere für den Off­ shore-Betrieb eignet.The invention relates to a wind turbine, which is particularly suitable for off suitable for shore operation.

Windkraftanlagen sind aus dem Stand der Technik bereits bekannt. Die DE 198 16 483 A1, DE 94 17 738 U1 und GB 2 286 637 A offenbaren Windkraftanla­ gen, die vorwiegend für das Festland geeignet sind, und die WO 99/43 956 A1 offenbart ein Verfahren zum Aufstellen von Offshore-Windkraftanlagen.Wind turbines are already known from the prior art. DE 198 16 483 A1, DE 94 17 738 U1 and GB 2 286 637 A disclose wind turbines gene, which are mainly suitable for the mainland, and WO 99/43 956 A1 discloses a method for installing offshore wind turbines.

Um den Zugang zu Offshore-Windkraftanlagen insbesondere bei rauher See zu verbessern, geht man mehr und mehr dazu über, das an dem Turm drehbar gelagerte Maschinengehäuse mit einer Plattform zu versehen, die von einem Hubschrauber angeflogen werden kann. Auf dieser Plattform kann ein Hub­ schrauber entweder aufsetzen oder aber der Hubschrauber schwebt über der Plattform (sogenannte Hoisting-Plattform), um z. B. Wartungspersonal abzu­ setzen oder abzuholen. Auf diese Weise sind diese Windkraftanlagen aus der luft "anfliegbar". Das Wartungspersonal ist darüber hinaus sogleich am Ort des Geschehens, nämlich am Maschinengehäuse und am Rotor, wo sich die meisten zu wartenden Bestandteile der Windkraftanlagen befinden. Allerdings bleibt es nicht aus, auch diejenigen elektrischen Komponenten, die sich im Regelfall unten im Turm in Höhe der Schiffsanlege-Plattform befinden (Schalteinrichtungen zum An- und Abkoppeln des Generators, Transformator, Umrichter etc.), warten bzw. austauschen zu müssen. Das Wartungspersonal muss dazu den Turm hinabsteigen, was als lästig und zeitaufwendig empfun­ den wird.To gain access to offshore wind turbines especially in rough seas improve, one goes more and more to the rotatable on the tower stored machine housing to be provided with a platform by a Helicopters can be approached. A hub either put the screwdriver on or the helicopter hovers over the Platform (so-called hoisting platform) to z. B. Maintenance personnel put or pick up. In this way, these wind turbines are out of the air "approachable". The maintenance staff is also immediately on site of the action, namely on the machine housing and on the rotor, where the most of the components of the wind turbines to be maintained. Indeed it does not fail, even those electrical components that are in the As a rule, they are located at the bottom of the tower at the level of the ship's platform (Switching devices for coupling and uncoupling the generator, transformer, Converter, etc.), to be serviced or replaced. The maintenance staff must descend the tower, which is annoying and time-consuming that will.

Es existieren bereits Windkraftanlagen, deren nahezu gesamte elektrische Komponenten im Maschinengehäuse bzw. oben im Turm untergebracht sind. There are already wind turbines, almost all of which are electrical Components are housed in the machine housing or at the top of the tower.  

Aus Zeitgründen wird jedoch gefordert, die wartungsintensiven elektrischen Komponenten schnell austauschen zu können. Bei den bekannten Windkraft­ anlagen müssen diese Komponenten einzeln aus dem Maschinengehäuse bzw. Turm entfernt und gegen neue ausgetauscht werden. Dies setzt das Entkop­ peln der elektrischen Verbindungen der einzelnen Komponenten untereinander sowie mit anderen Komponenten der Windkraftanlage voraus. Diese Art von Austausch ist recht Zeit- und damit kostenintensiv.However, due to time constraints, the maintenance-intensive electrical To be able to replace components quickly. With the well-known wind power systems, these components must be removed individually from the machine housing or Tower removed and replaced with new ones. This sets the decoupling the electrical connections between the individual components as well as with other components of the wind turbine. This kind of Exchange is quite time-consuming and therefore costly.

Es ist bereits bekannt, bei Offshore-Windkraftanlagen mit lediglich einer unten am Turm angeordneten Schiffsanlege-Plattform auf dieser einen Container an­ zuordnen, der wartungsintensive elektrische Komponenten wie z. B. Hoch- und Mittelspannungsschalter, Transformatoren und/oder Umrichter sowie Steuer­ einrichtungen beinhaltet. Dieser Container kann im Störfall oder zu Wartungs­ zwecken komplett gegen einen neuen ausgetauscht werden.It is already known in offshore wind turbines with only one below on the tower arranged ship docking platform on this a container assign the maintenance-intensive electrical components such. B. High and Medium voltage switches, transformers and / or converters and control facilities includes. This container can be used in the event of a malfunction or for maintenance completely replaced with a new one.

Der Erfindung liegt die Aufgabe zugrunde, eine Windkraftanlage zu schaffen, die im Hinblick auf sowohl die schnelle Behebung von Störungen als auch die Wartung der elektrischen Komponenten auch dann vorteilhaft ist, wenn sich das Personal der Windkraftanlage aus der Luft nähert.The invention has for its object to provide a wind turbine with regard to both the quick rectification of faults and the Maintenance of the electrical components is also advantageous if the wind turbine personnel approach from the air.

Zur Lösung dieser Aufgabe wird mit der Erfindung eine Windkraftanlage, ins­ besondere Offshore-Windkraftanlage vorgeschlagen, die versehen ist mit
To solve this problem, the invention proposes a wind turbine, in particular offshore wind turbine, which is provided with

  • - einem Turm,- a tower,
  • - einem am Turm drehbar gelagerten Maschinengehäuse,- a machine housing rotatably mounted on the tower,
  • - einem Rotor, der drehbar am Maschinengehäuse gelagert ist, und- A rotor, which is rotatably mounted on the machine housing, and
  • - einer an dem Maschinengehäuse angebrachten Landeplattform zum An­ fliegen durch einen Hubschrauber,- A landing platform attached to the machine housing fly through a helicopter,
  • - elektrischen Betriebsmitteln.- electrical equipment.

Diese Windkraftanlage ist erfindungsgemäß gekennzeichnet durch
einen Container, in dem zumindest Teile der elektrischen Betriebsmittel untergebracht sind, wobei
der Container zu einer Seite (Ober- oder Unterseite, Seitenwand, Rück­ wand) des Maschinengehäuses benachbart zu diesem angeordnet ist.According to the invention, this wind turbine is characterized by
a container in which at least parts of the electrical equipment are housed, wherein
the container to one side (top or bottom, side wall, rear wall) of the machine housing is arranged adjacent to this.

Bei der erfindungsgemäßen Windkraftanlage befinden sich die Schalteinrich­ tungen zum wahlweisen Verbinden des Generators mit und Entkoppeln des Generators von dem elektrischen Spannungsversorgungsnetz in einem Contai­ ner, der am Maschinengehäuse (neben, unterhalb, oberhalb) abnehmbar gela­ gert ist. Damit ist es zum einen möglich, zu Wartungszwecken sowie zu Zwe­ cken der Beseitigung von Störfällen den gesamten Container gegen einen neuen auszutauschen, also die störanfälligen elektrischen Betriebsmittel kom­ plett zu tauschen. Darüber hinaus ist die Anordnung des Containers oben am Maschinengehäuse insoweit von Vorteil, als dass das per Hubschrauber ankommende Wartungspersonal sich nicht erst bis ans untere Ende des Tur­ mes begeben muss, um an die Schalteinrichtungen zu gelangen, sondern diese sogleich wartungs- und austauschfreundlich im Container am Maschi­ nengehäuse vorfindet.The switching devices are located in the wind power plant according to the invention for connecting the generator with and decoupling the Generator from the electrical power supply network in a container ner, which on the machine housing (next to, below, above) detachably gela device. This makes it possible on the one hand for maintenance purposes and for two the elimination of accidents the entire container against one replace new ones, i.e. the fault-prone electrical equipment com to swap plett. In addition, the arrangement of the container is at the top Machine housing is advantageous insofar as that by helicopter incoming maintenance personnel do not first reach the bottom of the door mes must to get to the switchgear, but this immediately maintenance and exchange-friendly in the container on the machine finds housing.

Bei einem "Container", wie er zur Unterbringung zumindest eines Teils der elektrischen Betriebsmittel der Windkraftanlage im Sinne dieser Erfindung ver­ standen werden soll, handelt es sich um einen Behälter aus insbesondere Metall, dessen Abmessungen nicht notwendigerweise mit denen des zu Transportzwecken bekannten Transportcontainers übereinstimmen müssen. Auch ist es nicht zwingend erforderlich, dass der nach der Erfindung erforderliche Container stapelbar oder mit Beschlagelementen zum Zusammenwirken mit Lastzugelementen (Haken mit Seil oder Greifer) versehen sein muss. Allerdings ist letzteres sicherlich von Vorteil, wenn man daran denkt, dass der Container mittels einer Winde o. dgl. abgelassen werden können muss. Ferner soll mit dem Begriff "Landeplattform" im Sinne der Erfindung sowohl eine Plattform verstanden werden, auf der ein Hubschrauber landen kann, als auch eine sogenannte Hoisting-Plattform, über der der Hubschrauber zum Absetzen und Aufnehmen von Wartungspersonal in geringer Höhe schwebt. Schließlich werden im Sinne der Erfindung unter den elektrischen Betriebsmitteln der Windkraftanlage all diejenigen Komponenten verstanden, die entweder mechanische Energie in elektrische Energie umwandeln (z. B. Generator) oder mittels derer die elektrische Energie geschaltet, transformiert oder in anderer Weise verarbeitet wird.In the case of a "container" as used to accommodate at least part of the electrical equipment of the wind turbine in the sense of this invention ver should be stood, it is a container made in particular Metal whose dimensions are not necessarily the same as those of the Known transport container must match transport purposes. It is also not absolutely necessary that the according to the invention required containers stackable or with fittings for Interaction with trailer units (hook with rope or gripper) must be provided. However, the latter is certainly an advantage if you remember that the container is lowered by means of a winch or the like must be able to. Furthermore, the term "landing platform" in the sense of Invention can be understood both as a platform on which a helicopter can land, as well as a so-called hoisting platform over which the Helicopter to drop and pick up maintenance personnel in low height hovers. Finally, within the meaning of the invention  electrical equipment of the wind turbine all those components understood that either mechanical energy into electrical energy convert (e.g. generator) or by means of which the electrical energy switched, transformed or processed in any other way.

Neben den Schalteinrichtungen sind im Container auch ein Transformator und zweckmäßigerweise auch eine Umrichtereinheit untergebracht. Der Transfor­ mator kann dann entfallen, wenn der Generator selbst die erforderliche Hoch- bzw. Mittelspannung erzeugt. Die Umrichtereinheit ist nur dann erforderlich, wenn der Generator für einen drehzahlvariablen Betrieb ausgelegt ist. Die Schalteinrichtungen selbst sind in erster Linie Nieder- und/oder Mittel- und/oder Hochspannungsschalter, deren Funktionstüchtigkeit zu jedem Zeit­ punkt des Betriebs der Windkraftanlage gewährleistet sein muss. Die verschie­ denen Varianten sollen unter dem Begriff "Generatorsystem" verstanden wer­ den.In addition to the switching devices, there is also a transformer and expediently also accommodates a converter unit. The Transfor mator can be omitted if the generator itself has the required high or medium voltage generated. The converter unit is only required if if the generator is designed for variable-speed operation. The Switching devices themselves are primarily low and / or medium and / or high voltage switches, their functionality at all times operation of the wind turbine must be guaranteed. The different which variants should be understood under the term "generator system" who the.

Zweckmäßigerweise verfügt der Container über elektrische Anschlüsse, die über Verbindungsleitungen auf einfache Weise mit elektrischen Anschlüssen des Maschinengehäuses verbunden werden können. Damit ist die elektrische Entkopplung sowie Ankopplung des Containers an das Maschinengehäuse auf einfache Weise gewährleistet.The container expediently has electrical connections which via connecting lines with electrical connections in a simple manner of the machine housing can be connected. So that is electrical Decoupling and coupling the container to the machine housing guaranteed simple way.

Die Anordnung des Containers am Maschinengehäuse ist vorteilhafterweise dergestalt gelöst, dass sich der Container unterhalb eines über das Maschinen­ gehäuse überstehenden Teils der Landeplattform für den Hubschrauber befin­ det. Diese Positionierung hat darüber hinaus den Vorteil, dass der gesamte Container mittels einer im Hubschrauber angeordneten Winde abgelassen wer­ den kann, wenn er getauscht werden muss. Diese Winde kann aber auch auf der Landeplatteform, am Maschinengehäuse oder am Turm angebracht wer­ den. Die Anbringung der Winde z. B. außen am Turm in Höhe der Schiffsan­ lege-Plattform ist zu bevorzugen, da der Container, wenn er dann abgelassen werden muss, direkt auf ein Schiff abgelassen werden sollte und die Winde unten am Turm demzufolge von einer Person des Schiffspersonals, die sich auf der Schiffsanlege-Plattform befindet, installiert und bedient werden kann.The arrangement of the container on the machine housing is advantageous solved in such a way that the container is below one over the machine Projecting part of the landing platform for the helicopter det. This positioning also has the advantage that the entire Container is lowered by means of a winch arranged in the helicopter can if it needs to be exchanged. But this winch can also be on the landing plate shape, attached to the machine housing or to the tower the. The attachment of the winch z. B. outside the tower at the height of the ship Laying platform is preferable because the container when it is then lowered must be drained directly onto a ship and the winch  below on the tower, therefore, by a person of the ship's personnel who is on the ship berth platform is located, installed and operated.

Nachfolgend wird die Erfindung anhand der Zeichnung näher erläutert.The invention is explained in more detail below with reference to the drawing.

In der Zeichnung ist in Seitenansicht eine Offshore-Windkraftanlage 10 darge­ stellt, die einen im Meeresgrund verankerten Turm 12 mit einem um eine Ver­ tikalachse drehbaren Maschinengehäuse 14 am oberen Ende des Turmes 12 aufweist. Um eine Horizontalachse drehbar gelagert am Maschinengehäuse 14 ist der Rotor 16, der eine Nabe 18 und radial von dieser abstehende Rotor­ blätter 20 aufweist. Oberhalb des Meeresspiegels 22 befindet sich eine Platt­ form 24, die dann genutzt wird, wenn die Windkraftanlage 10 per Schiff ange­ fahren wird.In the drawing, a side view of an offshore wind turbine 10 is Darge, which has an anchored in the seabed tower 12 with a tical axis Ver rotating machine housing 14 at the upper end of the tower 12 . About a horizontal axis rotatably mounted on the machine housing 14 is the rotor 16 which has a hub 18 and radially projecting rotor blades 20 . Above the sea level 22 there is a platform 24 , which is used when the wind turbine 10 is driven by ship.

An dem dem Rotor 16 abgewandten hinteren Ende 26 des Maschinengehäuses 14 befindet sich eine Hubschrauber-Landeplattform 28, die einen über das hintere Ende 26 des Maschinengehäuses 14 überstehenden Bereich 30 auf­ weist. Unterhalb dieses Bereiches 30 der Landeplattform 28 befindet sich ein Container 32, der mechanisch an der Landeplattform 28 und/oder dem Maschinengehäuse 14 gelagert ist. In dem Container 32 befinden sich die Schaltanlagen für den Generator (nicht dargestellt) sowie Umrichter und Transformatoren. Diese elektrischen Komponenten sind über ebenfalls nicht dargestellte elektrische Kabel mit dem Generator sowie anderen elektrischen Komponenten des Maschinengehäuses 14 verbunden. Allgemein ausge­ sprochen befinden sich also in dem Container zumindest teilweise die elektri­ schen Betriebsmittel der Windkraftanlage 10.At the rear end 26 of the machine housing 14 facing away from the rotor 16 there is a helicopter landing platform 28 which has an area 30 projecting beyond the rear end 26 of the machine housing 14 . Below this area 30 of the landing platform 28 there is a container 32 which is mechanically mounted on the landing platform 28 and / or the machine housing 14 . The switchgear for the generator (not shown) as well as converters and transformers are located in the container 32 . These electrical components are connected to the generator and other electrical components of the machine housing 14 via electrical cables, also not shown. Generally speaking, the electrical equipment of the wind turbine 10 is at least partially located in the container.

Der Vorteil der hier beschriebenen Windkraftanlage 10 besteht in dem ein­ fachen Tauschen der elektrischen Komponenten des Containers 32 sowie der einfachen Zugänglichkeit dieser Komponenten direkt von einem auf der Lan­ deplattform 28 gelandeten Hubschrauber 34. Zu diesem Zweck weist der Container 32 eine begehbare Öffnung 36 auf. Mittels einer Seilwinde (nicht dargestellt), die entweder am Maschinengehäuse 14, an der Landeplattform 28, der Schiffsanlege-Plattform 24, dem Turm 12 oder im Hubschrauber 34 angeordnet ist, lässt sich der Container 32 absenken, um ihn beispielsweise auf ein Schiff zu verladen. Alternativ dazu ist es natürlich auch möglich, dass der Hubschrauber 34 den auszutauschenden Container 32 direkt abtranspor­ tiert und ein weitere Hubschrauber einen neuen Container 32 anliefert.The advantage of the wind power plant 10 described here consists in the simple replacement of the electrical components of the container 32 and the easy accessibility of these components directly from a helicopter 34 that has landed on the landing platform 28 . For this purpose, the container 32 has an accessible opening 36 . The container 32 can be lowered by means of a cable winch (not shown), which is arranged either on the machine housing 14 , on the landing platform 28 , on the landing stage 24 , on the tower 12 or in the helicopter 34 , for example to load it onto a ship . Alternatively, it is of course also possible that the helicopter 34 transports the container 32 to be replaced directly and another helicopter delivers a new container 32 .

Ferner kann der Container 32 auch zur Unterbringung des Generators dienen, wenn dieser im Maschinengehäuse 14 angeordnet ist und zu Zwecken des Austausches des ebenfalls im Maschinengehäuse 14 untergebrachten Getrie­ bes zwischengelagert werden muss. Diese Zwischenlagerung kann entfallen, wenn der Generator im Container 32 untergebracht ist oder im Maschinenge­ häuse 14 ausreichend Platz zur Zwischenlagerung vorhanden ist, um das Ge­ triebe trotz Unterbringung des Generators im Maschinengehäuse 24 auszu­ wechseln.Furthermore, the container 32 can also be used to accommodate the generator if it is arranged in the machine housing 14 and for the purposes of exchanging the gearbox also accommodated in the machine housing 14 must be temporarily stored. This intermediate storage can be omitted if the generator is housed in the container 32 or in the machine housing 14 there is sufficient space for intermediate storage to replace the gearbox despite housing the generator in the machine housing 24 .
