Description

Die Erfindung betrifft einen Vielpol-Synchrongenerator für getriebelose Horizontalachsen-Windkraftanlagen der im Patent anspruch 1 angegebenen Art mit Nennleistungen bis zu mehre ren Megawatt. The invention relates to a multi-pole synchronous generator for gearless horizontal-axis wind turbines of claim 1 in Patent specified type with power ratings up to several megawatts ren.

Stand der Technik sind Konzepte für getriebelose Windkraft anlagen mit permanentmagneterregtem Synchrongenerator, wie sie in Vortrag L4 der "European Community Wind Energy Conference" 1993 in Travemünde mit dem Titel "Multipole, permanent magnet generator studies and planed prototypes" oder in der Fachzeitschrift Windenergie Aktuell, Heft 7/1992 in dem Bericht "Konzepte für getriebelose WKA" vorgestellt wurden. State of the art concepts for gearless wind power plants with permanently synchronous generator as in lecture L4 of the "European Community Wind Energy Conference" in 1993 in Travemünde, entitled "Multi-pole permanent magnet generator studies and planed prototypes" or in the journal Wind Energy News Issue 7/1992 were presented in the report "concepts for gearless wind turbines." Ausgeführt ist in der obengenannten Leistungsklasse und Bauart bisher eine Anlage mit Synchrongenerator und Erregerwicklung der Firma ENERCON, siehe Produktbeschreibung zur ENERCON E40, mit einer Nennleistung von 500 kW. is performed in the above power class and type previously a plant with a synchronous generator and exciter winding ENERCON, see product description for ENERCON E40, with a rated power of 500 kW.

Die heute existierenden Anlagen und Konzepte haben folgende Nachteile: So sind die Generatoren entweder in herkömmlicher Bauweise mit mehrfach geteiltem Gehäuse ausgeführt, wobei der Rotor meist auf einer durch Umlaufbiegung belasteten Welle sitzt, was für die Einhaltung des Luftspaltes ein zu sätzliches Problem darstellt, oder der Generator ist einfach geteilt in Stator und Rotor, wobei jedes dieser Teile unter schiedlichen Baugruppen der Windkraftanlage zugeordnet ist. The currently existing systems and concepts have the following disadvantages: the generators are designed either in traditional construction with multi-split case, the rotor usually sitting on a loaded by rotating bending wave, which is too sätzliches problem for compliance with the air gap, or generator is simply divided into stator and rotor, each of said parts is associated difference union assemblies of the wind power plant. Insbesondere ist der Rotor an der Nabe der Windkraftanlage und der Stator an den Turmkopf bzw. die Achse der Windkraft anlage angeflanscht. In particular, the rotor on the hub of the wind turbine and the stator in the tower top or the axis of the wind power plant is flanged. In der zuletzt genannten Bauform kann der Generator nur bei einer bestimmten Windkraftanlage in einer Sonderanfertigung verwendet werden. In the last-mentioned design of the generator may be used only at a specific wind turbine in a custom-made product.

Die bekannte Situation ist aus der Sicht der Generatorher steller und der Hersteller der Windkraftanlagen in mehr facher Hinsicht unbefriedigend. The situation is known manufacturers from the perspective of Generatorher and manufacturer of wind turbines in several respects unsatisfactory. So kann ein bekannter Genera tor der vorgenannten, letztgenannten Bauweise nicht fertig montiert und funktionsgeprüft ausgeliefert werden. Thus, a known genera tor of the above, the latter construction will not be assembled and delivered functionally tested. Der Generatorhersteller muß Einfluß nehmen auf die Konstruktion des Windkraftanlagenherstellers, da die Einhaltung des Luft spaltes unbedingt gewährleistet sein muß. The generator manufacturer must take effect on the construction of the wind turbine manufacturer, since compliance with the air gap absolutely must be guaranteed. Der Generator muß schließlich in seiner Bauform an die von jedem Windkraft anlagenhersteller gewünschte Einbausituation angepaßt wer den. The generator must eventually in its design adapted to the system manufacturer of each wind power installation situation who desired the. Bei den zu erwartenden relativ geringen Stückzahlen ist diese Bauart für einen Generatorhersteller unwirtschaftlich. With the expected relatively small numbers of this type is uneconomical for a generator manufacturer.

Aufbauend auf dem vorgenannten Stand der Technik ist es Auf gabe der Erfindung, einen Vielpol-Synchrongenerator der ein gangs genannten Art zu schaffen, der sehr einfach aufgebaut und zuverlässig im Betrieb ist und insbesondere in unter schiedlich konzipierte Windkraftanlagen problemlos eingebaut werden kann. Based on the aforementioned prior art, it is on reproducing the invention to provide a multi-pole synchronous generator of a the type mentioned, which is very simple in construction and reliable in operation and can be easily installed especially among differently-designed wind turbines.

Gelöst wird die der Erfindung zugrundeliegende Aufgabe durch die im Patentanspruch 1 angegebenen Merkmale. which the object underlying the invention by the features indicated in patent claim 1 is achieved.

Vorteilhaft weitergebildet wird der Erfindungsgegenstand durch die Merkmale der Unteransprüche 2 bis 6. subject of the invention is advantageously developed by the features of the claims 2 to. 6

Wesen der Erfindung ist die Zusammenfassung der bisher ge trennten Komponenten Generator und Nabenlagerung zu einer einzigen Baugruppe, die im Gegensatz zu herkömmlichen Genera torkonzepten vorzugsweise aus lediglich zwei tragenden Bau teilen besteht. Essence of the invention is the combination of the previously separated components is ge share generator and hub bearing to a single assembly, the torkonzepten in contrast to conventional Genera preferably comprises only two supporting construction. Die Anordnung ermöglicht den Einbau der Generator-Baugruppe in unterschiedliche Anlagenkonzepte, z. The arrangement allows the installation of the generator assembly in different system concepts such. B. in Anlagen mit Blattverstellung (Pitch-geregelt) und Anlagen mit Leistungsbegrenzung durch Strömungsabriß (Stall-geregelt). As in systems with blade adjustment (pitch-controlled) and systems with power limitation by stall (stall regulated). Die Baugruppe stellt somit keine anlagenspezifi sche Sonderbauform dar und kann von verschiedenen Herstel lern von Windkraftanlagen als Zukaufteil geordert werden. The assembly therefore does not constitute anlagenspezifi specific special design and can learn from different herstel be ordered from wind turbines as a purchased part.

Aufgrund der Bauausführung kann auf eine zusätzliche Lage rung der Nabe mit den Rotorblättern verzichtet werden. Because of the construction can be dispensed with an additional layer tion of the hub with the rotor blades.

Die Generator-Baugruppe weist vorzugsweise integrierte wichtige Baukomponenten auf wie Kühlung, Generatordichtung, Bremse und/oder Feststellvorrichtung, Klemmenkasten sowie Schnittstellen zur Signalübertragung und Lagerschmierung. The generator assembly is preferably integrated important structural components such as cooling on, generator seal, brake and / or locking device, terminal box as well as interfaces for signal transmission and bearing lubrication.

Insbesondere durch die O-Anordnung der Lagerung mit kleinem Lagerabstand und verformungssteifem Stator und Rotor wird die Einhaltung des Generatorluftspaltes unter allen Belastungszuständen gewährleistet. In particular, by the O-arrangement of the bearing with a small distance between the bearings and the stator and rotor verformungssteifem compliance with the generator air gap is ensured under all load conditions.

Der Synchrongenerator besitzt vorzugsweise einen zentralen Durchgang, so daß die Nabe vom Innern des Turmkopfs aus im eingebauten Zustand des Generators in einer Windkraftanlage zugänglich ist. The synchronous generator preferably has a central passage, so that the hub from the inside of the tower head being accessible in the installed state of the generator in a wind turbine.

Zur Integration in eine Windkraftanlage sind insbesondere Anschlußflansche zur Nabe und zum Turmkopf der Windkraft anlage vorgesehen, die eine problemlose, einfache und siche re Montage an einer Windkraftanlage vor Ort ermöglichen. For integration into a wind turbine in particular flanges to the hub and the tower head of the wind power plant are provided, which allow easy, simple and Siche re installation on a wind turbine on site.

Die Erfindung wird nachfolgend anhand von Ausführungsbeispie len unter Bezugnahme auf die beigefügte Zeichnung mit Bezug auf den derzeitigen Stand der Technik näher beschrieben, es zeigen The invention is described below with reference to Ausführungsbeispie and with reference to the accompanying drawing with reference to the current state of the art in more detail, show

Fig. 2 einen Halbschnitt durch die Generatorbaugruppe gemäß Fig. 1 in größerer Einzelheit, Fig. 2 is a half section through the generator assembly of FIG. 1 in greater detail,

Fig. 3 eine Variante der Generatorbaugruppe ähnlich Fig. 2, und Fig. 3 shows a variant of the generator assembly similar to FIG. 2, and

Fig. 4 eine Ausführungsweise nach dem Stand der Technik, bei der der Generator einfach in Stator und Rotor geteilt ist, wobei jedes dieser Teile unterschied lichen Baugruppen der Windkraftanlage zugeordnet ist und der Generator in dieser Ausführungsvariante keine eigene Lagerung besitzt. Fig. 4 shows an embodiment according to the state of the art, in which the generator is simply divided into stator and rotor, wherein each of these parts is associated with different union assembly of the wind turbine and the generator in this embodiment has no bearing support.

In Fig. 1 ist in einem schematischen Halbschnitt ein Vielpol-Synchrongenerator 1 im eingebauten Zustand einer getriebelosen Horizontalachsen-Windkraftanlage gezeigt, wobei in Fig. 2 die Einzelheit der Generatorbaugruppe in einem Halbschnitt besonders herausgestellt ist. In Fig. 1, in a schematic half-section of a multi-pole synchronous generator 1 is shown in the installed state of a gearless horizontal-axis wind turbine, wherein in Fig. 2, the detail of the generator assembly is particularly exposed in a half-section.

Es handelt sich dabei um einen permanenterregten Synchron generator mit hoher Polzahl in einer Ausführung als Außen läufer. This is a permanent-magnet synchronous generator with high number of poles in an embodiment as external rotor. An den Rotor 11 des Generators ist die Nabe 2 ange flanscht. To the rotor 11 of the generator, the hub 2 is integrally flanged. Der Generator ist über den Anschlußflansch 14 mit dem Turmkopf 3 der Windkraftanlage verbunden. The generator is connected through the connecting flange 14 to the top of the tower 3 of the wind turbine. Der Turmkopf 3 ist seinerseits auf dem Turm 4 der Windkraftanlage drehbar gelagert. The tower head 3 is in turn rotatably mounted on the tower 4, the wind turbine.

Der Vielpol-Synchrongenerator 1 besitzt einen verformungs steif ausgebildeten Stator 8 und einen verformungssteif aus gebildeten Rotor 11 , die ihrerseits über eine fliegende Lage rung 15 innerhalb des Generators miteinander verbunden sind, die sowohl die Drehbewegung des Rotors abstützt als auch zur Aufnahme extern eingeleiteter Kräfte und Momente dient und dadurch eine zusätzliche Lagerung der Nabe mit den Rotorblät tern überflüssig macht. The multi-pole synchronous generator 1 comprises a stator deformation stiff formed 8 and a deformation-resistant of the formed rotor 11 tion in turn of a flying position 15 are connected to each other within the generator, which both supports the rotation of the rotor as well as for receiving external forces introduced and moments and thereby serves an additional bearing of the hub with the Rotorblät tern makes superfluous. Die Konstruktion, besonders die der Lagerung, ist so ausgelegt, daß der Vielpol-Synchrongenera tor als Baueinheit oder Verbindungselement zwischen Turmkopf 3 und Nabe 2 problemlos vor Ort einer Windkraftanlage inte griert werden kann. The design, particularly the storage is designed so that the multipolar sy tor as a structural unit or connecting element between the tower head 3 and the hub 2 can be inte grated easily on site of a wind turbine. Im Betrieb werden alle vom Wind über die Rotorblätter in die Nabe eingeleiteten Kräfte und Momente aufgenommen und in den Turmkopf 3 weitergeleitet. In operation, all initiated by the wind on the rotor blades into the hub forces and moments are recorded and forwarded to the tower head. 3

Wie insbesondere aus Fig. 2 zu entnehmen ist, ist der Rotor 11 mit Permanentmagneten 10 bestückt. As can be seen in particular from FIG. 2, the rotor 11 is equipped with permanent magnet 10. Die Dreiphasenwicklung mit Blechpaketen 9 sitzt auf dem Stator 8 . The three-phase winding with sheet packages 9 is seated on the stator. 8 Die fliegende Lagerung 15 zwischen Rotor und Stator ist hier durch zwei räumlich getrennte Kegellager in O-Anordnung ausgeführt. The floating bearing 15 between the rotor and stator is here performed by two spatially separate tapered roller bearings in an O arrangement. Die Ausführung der Lagerung 15 in O-Anordnung mit kleinem Lager abstand verhindert große Durchbiegungen bei großer Steifig keit, was die Einhaltung des Luftspaltes unter höchsten Bean spruchungen ermöglicht. The design of the bearing 15 in O arrangement with small bearing distance prevents large deflections at high Steifig ness, allowing spruchungen compliance of the air gap to the highest Bean.

In Fig. 3 ist die Lagerung 15 als einteiliges Lager ausge führt, wobei in dieser Darstellung auch ein Klemmenkasten 7 angedeutet ist, welcher in den Vielpol-Synchrongenerator 1 integriert ist. In Fig. 3, the storage 15 is executed as a one-piece bearing, which is indicated in this drawing, a terminal box 7, which is integrated into the multi-pole synchronous generator 1.

Die Baugruppe des Vielpol-Synchrongenerators 1 besteht im wesentlichen aus zwei tragenden Teilen, dem Rotor 8 und dem Rotor 11 , und es sind in die Baugruppe Kühlung 12 , Generator dichtung 5 , Bremse und/oder Feststellvorrichtung 6 , sowie vorgenannte Klemmenkasten 7 und auch Schnittstellen zur Signalübertragung und Lagerschmierung integriert. The assembly of the multi-pole synchronous generator 1 consists essentially of two supporting parts, the rotor 8 and the rotor 11, and there are in the module Cooling 12 generator seal 5, brake and / or locking device 6, and the aforementioned terminal box 7 and also interfaces integrated for signal transmission and bearing lubrication.

Der Vielpol-Synchrongenerator weist einen zentralen Durch gang 20 mit einem vergleichsweise großen Durchmesser auf. The multi-pole synchronous generator has a central passage 20 having a comparatively large diameter. Die Ausführung des Stators 8 mit großem Innendurchmesser läßt eine Wartung von Nabe 2 , Rotorblättern 15 und eventuell in die Nabe 2 integrierte Blattverstelleinrichtungen und Meß vorrichtung vom Innern des Turmkopfes 3 aus zu. The execution of the stator 8 with a large inner diameter allows a maintenance of hub 2, rotor blades 15 and eventually in the hub 2 and pitch mechanisms integrated measuring device to the interior of the tower head 3 from.

Durch die ungeteilte Ausführung von Stator 8 und Rotor 11 ist gegenüber herkömmlichen elektrischen Generatoren ein vereinfachter Zusammenbau gewährleistet. Through the execution of undivided stator 8 and the rotor 11, a simplified assembly is ensured over conventional electrical generators.

Da die gesamte Windkraftanlage im mechanischen Antriebs strang nur noch eine Lagerung besitzt, scheiden Fluchtungs fehler aus, wie sie bei Anlagen herkömmlicher Bauart auftre ten. Since the entire wind turbine in the mechanical driveline only has a bearing curse Tung ruled out errors as th in systems of traditional construction occurring defects.

Der Einbau der Baugruppe in eine Windkraftanlage wird insbe sondere durch die zwei klar definierten Anschlußflansche 13 und 14 zur Nabe 2 bzw. zum Turmkopf 3 erleichtert. The installation of the assembly in a wind turbine is in particular facilitated by the sondere two clearly defined flanges 13 and 14 to the hub 2 and to the tower head. 3

Ersichtlich ermöglicht die Erfindung es Generatorherstel lern, einen Vielpol-Synchrongenerator - permanentmagneterregt oder fremderregt - als abgeschlossene und getestete Bau gruppe für eine Montage einer Windkraftanlage zu liefern. Seen the invention enables learning Generatorherstel, a multi-pole synchronous generator - permanent magnet excited or externally excited - to deliver a completed and tested construction group for installation of a wind turbine. Die Windkraftanlage kann grundsätzlich unterschiedlich konzi piert sein, sofern die Anschlußflansche 13 und 14 klar defi niert sind. The wind turbine may be different piert konzi principle, provided that the connecting flanges 13 and 14 are clearly defi ned.
