    摘要: The invention relates to a method of controlling a wind turbine (10) comprising a nacelle (12), a rotating hub (13), a first rotor blade (171) and a second rotor blade (172). The method comprises the steps of i) measuring noise (27) by means of at least one noise detection device (21), the noise (27) being generated due to an interaction between the first rotor blade (171) of the wind turbine (10) and airflow (26) impinging on the first rotor blade (171); ii) determining the angular distribution and the intensity of the noise (27) by means of a controller (23); and iii) choosing the operational parameters of the wind turbine (10) based on the measured noise (27) by means of the controller (23) such that the performance of the wind turbine (10) is optimized. The choice of operational parameters includes individual pitching of the second rotor blade (172) and/or yawing the nacelle (12) of the wind turbine (10). Furthermore, the invention relates to a wind turbine (10) which is controlled by such a method.

    摘要: A wind turbine comprises a wind-driven rotor for converting wind energy to a mechanical driving force, a power converter for converting the driving force to exploitable power, and a drive train for rotatably transmitting the driving force from the wind-driven rotor to the power converter. The drive train includes: at least one rotatable driving element configured to provide at least one torsional resonance frequency in the drive train; a first detuner having at least one first mass element with a first mass inertia and at least one first elastic element with first elastic properties; and a second detuner having at least one second mass element with a second mass inertia and at least one second elastic element with second elastic properties. The first and second mass elements and first and second elastic elements are arranged to rotate during operation of the wind turbine. The torsional resonance frequency is influenced by the first and second mass inertias and the first and second first elastic properties.

    摘要: Gegenstand der Erfindung sind ein Verfahren und eine Anordnung zum Vermessen einer Windenergieanlage (1). Die Windenergieanlage (1) wird entsprechend einer Mehrzahl von Parametersätzen (P1, P2, P3) eingestellt. Es werden den Parametersätzen (P1, P2, P3) zugeordnete Messsätze (M1, M2, M3) aufgenommen, wobei jeder Messsatz (M1, M2, M3) mehrere zeitlich aufeinanderfolgende Messvektoren (V1...Vn) umfasst. Erfindungsgemäß wird in Zyklen zwischen den Parametersätzen (P1, P2, P3) gewechselt, und es werden für jeden Parametersatz (P1, P2, P3) in mehr als einem Zyklus Messvektoren (V1...Vn) aufgenommen. Durch die quasi-parallele Vermessung mehrerer Parametersätze (P1, P2, P3) werden eine erhebliche Zeitersparnis sowie eine verbesserte Vergleichbarkeit der Messungen erreicht.
