Description

Die Erfindung betrifft einen Vielpol-Synchrongenerator für getriebelose Horizontalachsen- Windkraftanlagen der im Patentanspruch 1 angegebenen Art mit Nennleistungen bis zu mehreren Megawatt. The invention relates to a multi-pole synchronous generator for gearless Horizontalachsen- wind power plants of the type indicated in claim 1 with power ratings up to several megawatts.

Stand der Technik sind Konzepte für getriebelose Windkraftanlagen mit permanentmagneterregten Synchrongenerator, wie sie in Vortrag L4 der "Eurpoean Community Wind Energy Conference" 1993 in Travemünde mit dem Titel "Muitipole, permanent magnet generator studies and planned 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 turbines with permanent magnet synchronous generator, as in lecture L4 of "Eurpoean Community Wind Energy Conference" in 1993 in Travemünde, entitled "Muitipole, permanent magnet generator studies and planned prototypes", or in the scientific journal Wind Energy News Issue 7/1992 were presented in the report "concepts for gearless wind turbines." Ausgeführt ist in der oben genannten Leistungsklasse und Bauart bisher nur 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 as yet a plant with a synchronous generator and exciter winding ENERCON, see product description for ENERCON E40, with a rated power of 500 kW. Weiterhin zeigen getriebelose Wind- bzw. Wasserkraftkonverter, wie in GB 2 050 525 A und DE 89 14 379 U1 dargestellt, den Stand der Technik für Einheiten mit kleiner Leistung, die überwiegend für den Einsatz im Wasser vorgesehen sind. Further show gearless wind or water power converter, as shown in GB 2050525 A and DE 89 14 379 U1, the prior art units having a small power which are primarily intended for use in the water. In diesen Baugrößen erweist sich die Zusammenführung von Rotor- und Generatorlager aus Konstruktions- und Kostengründen als sinnvoll, zumal die auftretenden Kräfte bei Anlagen der genannten Größenordnung gering sind. In these sizes, the merging of rotor and generator bearings from design and cost reasons, proves to be useful, especially since the forces are low in systems of that magnitude.

Die heute existierenden Anlagen und Konzepte haben 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 zusätzliches Problem darstellt, oder der Generator ist einfach geteilt, in Stator und Rotor, wobei jedes dieser Teile unterschiedlichen Baugruppen der Windkraftanlage zugeordnet ist. The currently existing systems and concepts have 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 an additional problem for compliance with the air gap, or the generator is simply divided, in the stator and rotor, each of these parts is associated with different components of the wind turbine. Insbesondere ist der Rotor an der Nabe der Windkraftanlage und der Stator an den Turmkopf bzw. die Achse der Windkraftanlage 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 turbine is flanged. In der zuletzt genannten Bauform kann der Generator nur bei einer Sonderanfertigung verwendet werden. In the latter design, the generator can only be used with a special design.

Die bekannte Situation ist aus der Sicht der Generatorhersteller und der Hersteller der Windkraftanlagen in mehrfacher Hinsicht unbefriedigend. The well-known situation is unsatisfactory from the perspective of the generator manufacturer and the manufacturer of the wind turbines in several ways. So kann ein bekannter Generator der vorgenannten, letztgenannten Bauweise nicht fertig montiert und funktionsgeprüft ausgeliefert werden. So a well-known generator of the above, the latter design can not fully assembled and delivered functionally tested. Der Generatorhersteller muß Einfluß nehmen auf die Konstruktion des Windkraftanlagenherstellers, da die Einhaltung des Luftspaltes unbedingt gewährleistet sein muß. The generator manufacturer must take effect on the construction of the wind turbine manufacturer, since compliance with the air gap must be absolutely guaranteed. Der Generator muß schließlich in seiner Bauform an die von jedem Windkraftanlagenhersteller gewünschte Einbausituation angepaßt werden. The generator must be adapted in its construction to the type of each wind turbine manufacturers installation situation finally. 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 Aufgabe der Erfindung, einen Vielpol-Synchrongenerator der eingangs genannten Art zu schaffen, der sehr einfach aufgebaut und zuverlässig im Betrieb ist und insbesondere in unterschiedlich konzipierte Windkraftanlagen problemlos eingebaut werden kann. Based on the aforementioned prior art, it is an object of the invention to provide a multi-pole synchronous generator of the type mentioned, which is very simple construction and is reliable in operation and can be installed easily in particular differently designed wind turbines.

Gelöst wird die der Erfindung zugrundeliegende Aufgabe durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmale. which the object underlying the invention by the features specified in the characterizing part of claim 1. is released.

Vorteilhaft weitergebildet wird der Erfindungsgegenstand durch die Merkmale des Unteransprüche 2 und 3. subject of the invention is advantageously developed by the features of dependent claims 2 and 3. FIG.

Wesen der Erfindung ist die Zusammenfassung der bisher getrennten Komponenten Generator und Nabenlagerung zu einer einzigen Baugruppe, die im Gegensatz zu herkömmlichen Generatorkonzepten vorzugsweise aus lediglich zwei tragenden Bauteilen besteht. Essence of the invention is the combination of the previously separate components generator, and hub bearing to a single assembly, which preferably consists of only two structural members, in contrast to conventional generator concepts. 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 anlagenspezifische Sonderbauform dar und kann von verschiedenen Herstellern von Windkraftanlagen als Zukaufteil geordert werden. The assembly thus does not constitute a plant-specific special design and can be ordered from various manufacturers of wind turbines as a purchased part.

Aufgrund der Bauausführung kann auf eine zusätzliche Lagerung der Nabe mit den Rotorblättern verzichtet werden. Because of the construction can be dispensed with an additional bearing 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 preferably has integrated major structural components, such as cooling, 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 verformungssteifen 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 deformation-resistant stator and rotor, the compliance of the generator air gap is ensured under all load conditions.

Der Synchrongenerator besitzt einen zentralen Durchgang, so daß die daran befestigte Nabe vom Innern des Turmkopfs aus zugänglich ist, zum Einbau von Elementen der Rotorblattverstellung oder zum Ausführen von Wartungsarbeiten. The synchronous generator has a central passage, so that the attached hub from the interior of the tower head being accessible for installation of elements of the rotor blade adjustment, or for performing maintenance work.

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

Die Erfindung wird nachfolgend anhand von Ausführungsbeispielen unter Bezugnahme auf die beigefügten Zeichnungen mit Bezug auf den derzeitigen Stand der Technik näher beschrieben; The invention is described in more detail below by means of embodiments with reference to the accompanying drawings with reference to the current state of the art; es zeigen: show it:

Fig. 1 einen Vielpol-Synchrongenerator in eingebautem Zustand in einer Windkraftanlage in einem schematischen Vertikalschnitt, Fig. 1 is a multi-pole synchronous generator in the installed state in a wind turbine in a schematic vertical section,

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 Ausführung nach dem Stand der Technik, bei der der Generator einfach in Stator und Rotor geteilt ist, wobei jedes dieser Teile unterschiedlichen Baugruppen der Windkraftanlage zugeordnet ist und der Generator in dieser Ausführungsvariante keine eigene Lagerung besitzt. Fig. 4 shows an embodiment according to the prior art, in which the generator is simply divided into stator and rotor, each of these parts is associated with different components 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 in eingebautem 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 wind power plant in the installed state of a gearless Horizontalachsen-, wherein in Fig. 2, the detail of the generator assembly is particularly exposed in a half-section.

Es handelt sich dabei um einen permanenterregten Synchrongenerator mit hoher Polzahl in einer Ausführung als Außenläufer. This is a permanent magnet synchronous generator with high number of poles in an embodiment of an external rotor. An den Rotor 11 des Generators ist die Nabe 2 angeflanscht. To the rotor 11 of the generator, the hub 2 is 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 verformungssteif ausgebildeten Rotor 11 , die ihrerseits über eine fliegende Lagerung 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 Rotorblättern überflüssig macht. The multi-pole synchronous generator 1 has a deformation-resistant shaped rotor 11, which in turn are connected via a floating bearing 15 within the generator together, both supporting the rotation of the rotor as also serves for receiving externally initiated forces and moments and thus an additional bearing of the hub eliminates with the rotor blades. Die Konstruktion, besonders die der Lagerung, ist so ausgelegt, daß der Vielpol-Synchrongenerator als Baueinheit oder Verbindungselement zwischen Turmkopf 3 und Nabe 2 problemlos vor Ort einer Windkraftanlage integriert werden kann. The design, particularly the storage is designed so that the multi-pole synchronous generator can be integrated as a structural unit or connecting element between the tower head 3 and the hub 2 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 mit kleinem Lagerabstand ausgeführt. The floating bearing 15 between the rotor and stator is here executed with a small bearing clearance by two spatially separate tapered roller bearings in an O arrangement. Die Ausführung der Lagerung 15 in O- Anordnung mit kleinem Lagerabstand verhindert große Durchbiegungen bei großer Steifigkeit, was die Einhaltung des Luftspaltes unter höchsten Beanspruchungen ermöglicht. The design of the bearing 15 in O arrangement with a small distance between the bearings prevents large deflections at high stiffness, which enables compliance with the air gap under excessive use.

In Fig. 3 ist die Lagerung 15 als einteiliges Lager ausgeführt, 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 constructed as a one-piece bearing, in this illustration, a terminal box is indicated 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 Stator 8 und dem Rotor 11 , und es sind in die Baugruppe Kühlung 12 , Generatordichtung 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 stator 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 to the signal transmission and bearing lubrication integrated.

Der Vielpol-Synchrongenerator weist einen zentralen Durchgang 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 Meßvorrichtungen vom Innern des Turmkopfes 3 aus zu. The execution of the stator 8 with a large inner diameter allows for a maintenance of the hub 2, rotor blades 15 and eventually in the hub 2 integral pitch mechanisms and measuring devices from the interior of the tower head 3 from. Außerdem ist die Durchführung von Antriebselementen zur Blattverstellung möglich. In addition, the implementation of power transmission components for blade adjustment is possible.

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 Antriebsstrang nur noch eine Lagerung besitzt, scheiden Fluchtungsfehler aus, wie sie bei Anlagen mit herkömmlicher Bauart auftreten. Since the entire wind turbine has only one bearing in the mechanical drive train, alignment errors are eliminated as they occur in systems with conventional design.

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

Ersichtlich ermöglicht die Erfindung es Generatorherstellern, einen Vielpol- Synchrongenerator - permanentmagneterregt oder fremderregt - als abgeschlossene und getestete Baugruppe für eine Montage einer Windkraftanlage zu liefern. Apparent, the invention allows it generator manufacturers, a synchronous generator Vielpol- - permanent magnet excited or externally excited - to provide completed and tested as a mounting assembly for a wind turbine. Die Windkraftanlage kann grundsätzlich unterschiedlich konzipiert sein, sofern die Anschlußflansche 13 und 14 klar definiert sind. The wind turbine can basically be designed differently unless the connecting flanges 13 and 14 are clearly defined.
