Description
Die vorliegende Erfindung betrifft eine Windenergieanlage mit einem Rotor mit wenigstens einem Rotorblatt und einer Verstelleinrichtung für das Rotorblatt.The The present invention relates to a wind turbine with a Rotor with at least one rotor blade and an adjusting device for the Rotor blade.
Solche Windenergieanlagen sind im Stand der Technik seit langem bekannt und werden auch in der Fachliteratur beschrieben. So z.B. bei Erich Hau in "Windkraftanlagen", Springer-Verlag, 2. Auflage, 1996, Seiten 231 ff.Such Wind turbines have long been known in the art and are also described in the specialist literature. For example, with Erich Home in "wind turbines", Springer-Verlag, 2nd edition, 1996, pages 231 ff.
Diese Verstelleinrichtung muss so ausgelegt sein, dass sie das Rotorblatt bzw. bei einer zentralen Rotorblattverstellung die Rotorblätter in einer akzeptablen Zeit in eine vorgebbare Position stellen kann. Dazu ist im Stand der Technik häufig ein Motor vorgesehen, der eine durch die Rotorblätter und deren Lasten vorgegebene Mindestleistung aufweisen muss.These Adjustment device must be designed so that it covers the rotor blade or at a central rotor blade adjustment, the rotor blades in can set an acceptable time in a predetermined position. To is common in the art a motor is provided which provides a predetermined by the rotor blades and their loads Minimum performance must have.
Aus
Aus
Unabhängig von Betrachtungen zum Einsatz und zur Auslegung von Getrieben ist leicht prognostizierbar, dass mit steigender Anlagengröße auch die Rotorblätter größer werden und somit auch der zur Rotorblattverstellung verwendete Motor eine höhere Leistung bereitstellen muss. Diese höhere Leistung führt unvermeidlich zu größeren Abmessungen des Motors.Independent of Considerations for the use and design of gearboxes is easy Predictable that with increasing plant size and the rotor blades are larger and thus also the motor used for rotor blade adjustment higher performance must provide. This higher Performance leads inevitably to larger dimensions of the motor.
Aufgabe der vorliegenden Erfindung ist es daher, eine Windenergieanlage der eingangs genannten Art derart weiterzubilden, dass die genannten Nachteile im Stand der Technik vermieden werden.task The present invention is therefore a wind turbine of the type mentioned in such a way that said Disadvantages in the prior art can be avoided.
Dies wird erfindungsgemäß durch eine Windenergieanlage mit dem Merkmal nach Anspruch 1 verwirklicht. Bei der erfindungsgemäßen Windenergieanlage weist die Verstelleinrichtung wenigstens zwei Antriebe auf, die beim Verstellen des Rotorblattes gleichzeitig die zur Verstellung notwendige Kraft in das Rotorblatt einleiten.This is inventively a wind turbine with the feature of claim 1 realized. In the wind power plant according to the invention the adjusting device has at least two drives which when adjusting the rotor blade at the same time for adjustment introduce necessary force into the rotor blade.
Weiterhin ist es erfndungsgemäß möglich, verfügbare Antriebe zu verwenden, die jetzt schon in großen Stückzahlen zur Verfügung stehen und die auch im Dauerbetrieb bereits erprobt sind. Darüber hinaus sind Vorrichtungen und Verfahren für deren Handhabung bereits bekannt und erprobt.Farther it is erfndungsgemäß possible, available drives to use, which are already available in large quantities and have already been tested in continuous operation. Furthermore are already devices and methods for their handling known and tested.
In einer besonders bevorzugten Ausführungsform der Erfindung sind die Antriebe Elektromotoren, nämlich bevorzugt Gleichstrommotoren. Im Fall einer Störung können diese Elektromotoren mit einer vorhandenen Notstromversorgung, z. B. in Form einer Batterie, verbunden werden.In a particularly preferred embodiment According to the invention, the drives are electric motors, namely preferred DC motors. In the case of a fault, these electric motors with a existing emergency power supply, z. B. in the form of a battery connected become.
Es ist auch möglich, für die Elektromotoren Drehstrom-Asynchronmotoren zu verwenden. Zur Erzeugung eines Bremsmomentes werden dann diese Motoren nach der Abschaltung des während des Rotorblatt-Verstellvorganges fließenden Drehstromes mit einem Gleichstrom beaufschlagt, so dass in den Asynchronmotoren ein stehendes Magnetfeld erzeugt wird. Dadurch können die noch drehenden Motoren abgebremst werden und in den stillstehenden Motoren wird ein Bremsmoment beibehalten.It is possible, too, for the Electric motors to use three-phase asynchronous motors. To produce a braking torque then these motors after shutdown during the the rotor blade adjustment process flowing three-phase current with a DC applied, so that in the asynchronous motors a standing Magnetic field is generated. This allows the still rotating engines be braked and in the stationary motors is a braking torque maintained.
Weiterevorteilhafte Ausführungsformen der Erfindung sind in den Unteransprüchen beschrieben.More Advantageous embodiments The invention are described in the subclaims.
Im Folgenden wird eine Ausführungsform der Erfindung anhand der beigefügten Figuren beschrieben. Dabei zeigen:in the Following is an embodiment of the Invention with reference to the attached Figures described. Showing:

beaufschlagt dadurch, dass jeder der Verstellantriebe nur noch einen
Teil, im konkreten Beispiel nur noch ein Drittel, der erforderlichen

Diese

Dadurch können die Verstellantriebe bei spontanen Lastwechseln an den Rotorblättern, z.B. bei böigen Winden, die sprunghaft und kurzzeitig ihre Richtung ändern, so dass eine sinnvolle Rotorblattverstellung nicht möglich ist, eine Bremswirkung ausüben.Thereby can the adjusting drives during spontaneous load changes on the rotor blades, e.g. at gusty Winches that change their direction abruptly and for a short time that a meaningful rotor blade adjustment is not possible exert a braking effect.
Die
drei Verstellantriebe
Fällt einer der Verstellantriebe aus, sind zwar die Lasten, die dann auf den zwei verbleibenden Verstellantrieben liegen, größer als zuvor, allerdings ist jeder Verstellantrieb so ausgelegt, dass er auch für längere Zeit im Überlastbetrieb gefahren werden kann. Insofern ist also jeder einzelne Verstellantrieb etwas überdimensioniert, um für den Fall, dass einer der Verstellantriebe ausfällt, noch für eine gewisse Zeit im Überlastbetrieb gefahren werden kann, zumindestens so lange, um einen sicheren Stopp der Windenergieanlage einzuleiten bzw. die Rotorblätter in Fahnenstellung zu bringen.Falls one of the adjusting, are indeed the loads, which then on the two remaining adjusting drives are larger than before, but each is Adjusting drive designed so that it is in overload operation for a long time can be driven. In this respect, therefore, each individual adjustment is slightly oversized, around for the case that one of the adjusting drives fails, even in overload operation for a certain time can be driven, at least as long to make a safe stop initiate the wind turbine or the rotor blades in To bring the flag position.
Kommt
es nun zu einem Stromausfall, wird auch der Schütz abfallen und die Kontakte
des Schützes
werden umschalten und in ihrer Ruhelage den Verstell antrieb
