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 horizontal axes. Wind turbines of the type specified in claim 1 with nominal powers 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. 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. 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. 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.State of the art are concepts for gearless wind turbines permanent magnet excited synchronous generator, as described in lecture L4 of the "Eurpoean Community Wind Energy Conference "1993 in Travemünde with the title" Muitipole, permanent magnet generator studies and planned prototypes ", or in the journal Wind Energy News Issue 7/1992 in the report "Concepts for gearless wind turbines" were presented. Has been carried out in the above-mentioned performance class and design only one system with synchronous generator and field winding from ENERCON, see Product description for the ENERCON E40, with a nominal output of 500 kW. Farther show gearless wind or hydropower converters, as in GB 2 050 525 A. and DE 89 14 379 U1, the prior art for units with small Performance that is primarily intended for use in water. In these The merging of rotor and generator bearings has proven to be of great size Design and cost reasons make sense, especially since the forces that occur in systems of the order of magnitude mentioned are small.

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. Insbesondere ist der Rotor an der Nabe der Windkraftanlage und der Stator an den Turmkopf bzw. die Achse der Windkraftanlage angeflanscht. In der zuletzt genannten Bauform kann der Generator nur bei einer Sonderanfertigung verwendet werden. The systems and concepts that exist today have disadvantages: That's how they are Generators either in a conventional design with a multiple split housing executed, whereby the rotor is usually seated on a shaft loaded by recirculating bending, which is an additional problem for maintaining the air gap, or the Generator is simply divided into stator and rotor, with each of these parts being different Assemblies of the wind turbine is assigned. In particular, the rotor is on the hub the wind turbine and the stator to the tower head or the axis of the wind turbine flanged. In the latter design, the generator can only be used with one Custom order can be used.  

Die bekannte Situation ist aus der Sicht der Generatorhersteller und der Hersteller der Windkraftanlagen in mehrfacher Hinsicht unbefriedigend. So kann ein bekannter Generator der vorgenannten, letztgenannten Bauweise nicht fertig montiert und funktionsgeprüft ausgeliefert werden. Der Generatorhersteller muß Einfluß nehmen auf die Konstruktion des Windkraftanlagenherstellers, da die Einhaltung des Luftspaltes unbedingt gewährleistet sein muß. Der Generator muß schließlich in seiner Bauform an die von jedem Windkraftanlagenhersteller gewünschte Einbausituation angepaßt werden. Bei den zu erwartenden relativ geringen Stückzahlen ist diese Bauart für einen Generatorhersteller unwirtschaftlich.The known situation is from the perspective of the generator manufacturer and the manufacturer of the Wind turbines unsatisfactory in several ways. So a well-known generator the aforementioned, latter construction not fully assembled and function tested be delivered. The generator manufacturer must influence the construction of the Wind turbine manufacturer, since compliance with the air gap is absolutely guaranteed have to be. Finally, the generator must match the design of everyone Wind turbine manufacturers can be adapted to the desired installation situation. With the too expected relatively small quantities, this design is for a generator manufacturer uneconomical.

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.Building on the aforementioned prior art, it is an object of the invention to To create multi-pole synchronous generator of the type mentioned, the very simple constructed and reliable in operation and especially in differently designed Wind turbines can be easily installed.

Gelöst wird die der Erfindung zugrundeliegende Aufgabe durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmale.The object on which the invention is based is achieved by the characterizing Part of claim 1 specified features.

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

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. Die Anordnung ermöglicht den Einbau der Generator-Baugruppe in unterschiedliche Anlagenkonzepte, z. B. in Anlagen mit Blattverstellung (Pitch-geregelt) und Anlagen mit Leistungsbegrenzung durch Strömungsabriß (Stall-geregelt). Die Baugruppe stellt somit keine anlagenspezifische Sonderbauform dar und kann von verschiedenen Herstellern von Windkraftanlagen als Zukaufteil geordert werden.The essence of the invention is the summary of the previously separated components Generator and hub bearing to a single assembly, as opposed to conventional generator concepts preferably consist of only two load-bearing components consists. The arrangement enables the installation of the generator assembly in different system concepts, e.g. B. in systems with blade adjustment (pitch-controlled) and Systems with capacity limitation due to stalling (stall-regulated). The assembly is therefore not a system-specific special design and can be of different types Manufacturers of wind turbines can be ordered as purchased parts.

Aufgrund der Bauausführung kann auf eine zusätzliche Lagerung der Nabe mit den Rotorblättern verzichtet werden.Due to the construction, the hub can be additionally supported with the Rotor blades can be dispensed with.

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 important 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 due to the O-arrangement of the bearing with a small bearing distance and Deformation-resistant stator and rotor will keep the generator air gap below guaranteed 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 it attached hub is accessible from the inside of the tower head, for the installation of elements the rotor blade adjustment or to carry out 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, there are in particular connection flanges to the hub and provided for the tower head of the wind turbine, which is a problem-free, simple and Enable safe installation on 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; es zeigen:The invention is described below using exemplary embodiments with reference to the accompanying drawings with reference to the current state of the art described; 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 a stator and rotor, each of these parts being assigned to different assemblies of the wind power plant and the generator in this embodiment variant not having its own bearing.

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, a multi-pole synchronous generator 1 is shown in the installed state of a gearless horizontal-axis wind turbine in a schematic half-section, with the detail of the generator assembly being particularly emphasized in a half-section in Fig. 2.

Es handelt sich dabei um einen permanenterregten Synchrongenerator mit hoher Polzahl in einer Ausführung als Außenläufer. An den Rotor 11 des Generators ist die Nabe 2 angeflanscht. Der Generator ist über den Anschlußflansch 14 mit dem Turmkopf 3 der Windkraftanlage verbunden. Der Turmkopf 3 ist seinerseits auf dem Turm 4 der Windkraftanlage drehbar gelagert.It is a permanently excited synchronous generator with a high number of poles in an external rotor version. The hub 2 is flanged to the rotor 11 of the generator. The generator is connected to the tower head 3 of the wind turbine via the connecting flange 14 . The tower head 3 is in turn rotatably mounted on the tower 4 of 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. 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. Im Betrieb werden alle vom Wind über die Rotorblätter in die Nabe eingeleiteten Kräfte und Momente aufgenommen und in den Turmkopf 3 weitergeleitet.The multi-pole synchronous generator 1 has a deformation-resistant rotor 11 , which in turn is connected to one another via a floating bearing 15 within the generator, which both supports the rotary movement of the rotor and also serves to absorb externally introduced forces and moments, and thereby an additional bearing of the hub with the rotor blades. The construction, especially the storage, is designed so that the multi-pole synchronous generator can be easily integrated as a structural unit or connecting element between tower head 3 and hub 2 on site of a wind turbine. In operation, all the forces and moments introduced by the wind via the rotor blades into the hub are absorbed and passed on to the tower head 3 .

Wie insbesondere aus Fig. 2 zu entnehmen ist, ist der Rotor 11 mit Permanentmagneten 10 bestückt. Die Dreiphasenwicklung mit Blechpaketen 9 sitzt auf dem Stator 8. Die fliegende Lagerung 15 zwischen Rotor und Stator ist hier durch zwei räumlich getrennte Kegellager in O-Anordnung mit kleinem Lagerabstand ausgeführt. 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.As can be seen in particular from FIG. 2, the rotor 11 is equipped with permanent magnets 10 . The three-phase winding with laminated cores 9 sits on the stator 8 . The floating bearing 15 between the rotor and the stator is designed here by two spatially separate tapered bearings in an O arrangement with a small bearing spacing. The design of the bearing 15 in an O arrangement with a small bearing spacing prevents large deflections with great rigidity, which enables the air gap to be maintained under the highest loads.

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 bearing 15 is designed as a one-piece bearing, a terminal box 7 is also indicated in this illustration, which is integrated in 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 cooling 12 , generator seal 5 , brake and / or locking device 6 , as well as the aforementioned terminal box 7 and also interfaces to the assembly Signal transmission and bearing lubrication integrated.

Der Vielpol-Synchrongenerator weist einen zentralen Durchgang 20 mit einem vergleichsweise großen Durchmesser auf. 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. Außerdem ist die Durchführung von Antriebselementen zur Blattverstellung möglich. The multi-pole synchronous generator has a central passage 20 with a comparatively large diameter. The design of the stator 8 with a large inner diameter allows maintenance of the hub 2 , rotor blades 15 and possibly blade adjustment devices and measuring devices integrated into the hub 2 from the inside of the tower head 3 . In addition, the implementation of drive elements for blade adjustment is possible.

Durch die ungeteilte Ausführung von Stator 8 und Rotor 11 ist gegenüber herkömmlichen elektrischen Generatoren ein vereinfachter Zusammenbau gewährleistet.The undivided design of the stator 8 and rotor 11 ensures a simplified assembly compared to 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 in the mechanical drive train is only one bearing misalignment, as is the case with systems of conventional design occur.

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 facilitated in particular by the two clearly 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. Die Windkraftanlage kann grundsätzlich unterschiedlich konzipiert sein, sofern die Anschlußflansche 13 und 14 klar definiert sind.Obviously, the invention enables generator manufacturers to deliver a multi-pole synchronous generator - permanently magnet-excited or externally excited - as a closed and tested assembly for an assembly of a wind power plant. The wind turbine can basically be designed differently, provided the connecting flanges 13 and 14 are clearly defined.
