    摘要: Verfahren zum Überwachen des Betriebs einer Windenergieanlage (1), die einen von einem Windrotor (12) mit mindestens einem Rotorblatt (13), dessen Pitchwinkel (θ) verstellbar ist, angetriebenen Generator (15) zur Abgabe elektrischer Leistung aufweist, wobei die Windenergieanlage (1) mit einem vorgebbaren Leistungsreduktionssollwert (r) betrieben werden kann. Erfindungsgemäß ist vorgesehen ein Bestimmen, ob die Windenergieanlage (1) reduziert betrieben wird oder nicht, umfassend die Schritte: Bestimmen, ob eine Veränderung eines Windrotorbetriebsparameters (ausgewählt aus einer Gruppe bestehend aus einer Drehzahl des Windrotors und dem Pitchwinkel (θ)) gegenüber einem Referenzwert (θ ref ) vorliegt, Bestimmen, ob die Windenergieanlage (1) im Teillastbetrieb läuft, Prüfen, ob ein Leistungsreduktionssollwert (r) vorgegeben ist, und Ausgeben eines Signals für eine wirksame Reduktion ("E") dann, wenn alle vorgenannten Bedingungen erfüllt sind. Es wird somit durch eine Kombination von Windrotorbetriebsparameterüberwachung einerseits und Fallunterscheidung hinsichtlich der Betriebsart und des Vorhandenseins eines Leistungsreduktionssollwerts (r) andererseits erkannt, ob eine tatsächliche, das heißt wirksame Reduktion stattfindet. Die Erfindung bezieht sich ferner auf eine zum entsprechenden Betrieb ausgebildete Windenergieanlage (1).

    摘要: A method for operating a wind turbine is provided. The wind turbine 10 generates a sound level 140. The method includes selecting a desired sound level 210; calculating at least one operating parameter by inputting the desired sound level to a model; and operating the wind turbine according to the at least one operating parameter. The method further includes measuring the sound level 140 and based on the measured sound level 340, calculating at least one of a redefined desired sound level and a revised model. Furthermore, the method includes calculating at least one redefined operating parameter by at least one of inputting the redefined desired sound level 210 to the model and inputting the desired sound level to the revised model.

    摘要: An adaptive wind turbine generator (WTG) control system comprising a measurement system MS with sensors A1, A2, MC arranged to perform measurements of mechanical vibrations of one or more mechanical components of the WTG, at a plurality of operating conditions for the WTG. A storage unit SU stores, in a measurement database MD, measured data and corresponding operating condition OC data for the WTG. An operating condition manager OCM determines how to operate the WTG, including rotor speed PSC, according to a control algorithm in response to the data stored in the measurement database MD. Hereby, individual vibration measurements on critical components such as electric power generator and blades of the WTG can be taken into account in determining which rotor speed windows to avoid. This allow a more power efficient WTG, since a large safety margin around calculated or predetermined tabulated rotor speed windows can be avoided. Further, with a continuous update of the measurements, the control system can take into account variations in the vibration behaviour of the components over time.
