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： Apparatus for detecting aerodynamic conditions of a rotor blade (22) of a wind turbine (10). An acoustic sensor (24) may be remotely located from the rotor blade. The sensor may be focused to monitor a portion of a blade path swept by the rotor blade to detect an aerodynamic condition such as flow separation, and may provide input to a controller (27) for control of a pitch of the blade effective to prevent the flow separation from developing into a full stall condition. One sensor may be focused to monitor blades of more than one wind turbine. A plurality of such sensors in a wind park may be connected to a supervisory controller (120) to predict the propagation of wind conditions progressing through the park.

摘要： A method of controlling noise emission of a wind park includes monitoring noise emitted from the wind park by detecting and identifying noise emitted by some or all of the plurality of the wind park's wind turbines (101 ... 108) and estimating the level thereof. If the level of the monitored noise exceeds a predetermined noise threshold the wind park controller commands one or more of the wind turbines, chosen by the importance of its or their relative influence on the noise emitted from the wind park to the measuring location, to change operation to an operation mode with reduced noise emission.
