Title
(DE) Verfahren zum Betrieb einer Windenergieanlage
Abstract
(DE)

Die Erfindung betrifft ein Verfahren zum Betrieb einer Windenergieanlage (1) und eine zur Durchführung des Verfahrens ausgebildete Windenergieanlage (1) sowie ein entsprechendes Computerprogrammprodukt. Bei dem Verfahren zum Betrieb einer Windenergieanlage (1) umfassend einen Rotor (3) mit winkelverstellbaren Rotorblättern (5) und einen damit drehverbundenen Generator (9) mit steuerbarem Drehmoment, wird das Drehmoment des Generators (9) auf einem Maximalwert begrenzt, der mit dem Blattwinkel der Rotorblätter (5) derart verknüpft ist, dass der Maximalwert bei dem Einschalt-Blattwinkelwert kleiner gleich dem Drehmomentnennwert (MNenn) und der Maximalwert bei einem von dem Einschalt-Blattwinkel abweichenden Nennblattwinkel gleich dem Drehmomentnennwert (MNenn) ist. embedded image
