摘要： A wind turbine (1) is provided, having a wind turbine tower (2) and at least one rotatable blade (5), and further comprising a system for measuring rotor blade vibration of said wind turbine. The system comprises at least one Doppler radar unit (7) operatively configured to emit and receive radar signals, the radar unit being mounted on the wind turbine tower at a position above the lowest position of the at least one blade, the radar unit being positioned so as to measure reflections of an emitted radar signal from the turbine blade. A processing unit is configured to receive measurement data from the radar unit and to determine, by analysis of Doppler shift in received radar signals relative to transmitted signals due to movement of the blade towards or away from the turbine tower, the velocity of the blade in the direction towards or away from the turbine tower. Using a radar unit to measure blade velocity allows a determination to be made of the vibrations occurring in the blade without needing an internal sensor in the blade. This reduces manufacturing and maintenance costs of the blades since sensors in the blades will not need to be replaced, and sensors positioned on the tower are easier to replace in the field.

摘要： The present invention relates to a method for controlling a wind turbine,in particular a method for controlling pitch of one or more blades of a wind turbine and related system. The method comprises collecting first data indicative of a dynamic condition of the first wind turbine blade and the rotor, the first data comprising rotor data and first deflection data, the rotor data being indicative of the azimuth position and rotational velocity of the rotor in a rotor plane perpendicular to the rotor axis, and the first deflection data being indicative of the position, speed and acceleration of one or more parts of the first wind turbine blade. Further, the method comprises calculating an expected tower clearance distance at a later time of tower passage for the first wind turbine blade based on the first data including acceleration of one or more parts of the first wind turbine blade, and performing measures to prevent tower collision, if the expected tower clearance distance fulfills a collision risk criterion.

摘要： The present invention relates to a blade for a wind power plant with an assembly face for mounting in a circular pitch bearing, whose pitch axis is angled relative to the longitudinal axis of the blade, and wherein the blade comprises a root part with an approximately elliptic cross-section, in which root part the assembly face is arranged. The invention further relates to a wind power plant in general having a pitch- adjustable blade mounted in a pitch bearing such that the distance between the outermost part of the blade and the tower is increased when the leading edge of the blade is pitched up in the wind. This is accomplished in that the longitudinal axis of the blade is angled in a particular way compared to its pitch axis. The invention also relates to a method of controlling a wind power plant, including to increase the rotor area and/or increasing the distance between the outermost part of at least one blade and the tower by regulating, during operation, the pitch of a blade about a pitch axis which is angled relative to the longitudinal axis of the blade.

摘要： A system for identifying the likelihood of a wind turbine rotor blade striking a wind turbine tower comprises a device for sensing bending of a wind turbine rotor blade and a device for sensing bending of a wind turbine tower. In a preferred embodiment Long Period Grating (LPG) sensors are used to measure bending of the tower. Preferably a plurality of LPG sensors is provided along the length of the blade. In one embodiment at least one of the LPG sensors comprises two sensing elements arranged to sense in perpendicular directions. In another embodiment a plurality of LPG sensors are provided each on different sides of the wind turbine tower. A processor uses the sensed blade and tower bending to determine whether the distance between the blade and the tower will be below a predetermined minimum value. If the distance is determined to be below the predetermined minimum value a controller may be used to adjust a wind turbine variable to reduce loading on the blade and thereby reduce the likelihood of a tower strike.

摘要： Die Erfindung betrifft die Bestimmung der Durchbiegung bzw. Verformung eines Rotorblattes einer Windkraftanlage und basiert auf der Kombination aktiver Funkpeilung mit einer Inertialsensorik. Eine Phased-Array-Antenne wird auf dem Maschinenhaus der Windkraftanlage befestigt und bspw. in Richtung der Spitze des Rotorblattes ausgerichtet, wenn sich diese im höchsten Punkt der Umdrehung des Rotorblattes befindet. An der Spitze des Rotorblattes wird ein Transponder mit einem Sender, der ein Signal S aussendet, sowie einer Inertialsensorik befestigt. Mit der Phased-Array-Antenne wird anhand des Signals S immer dann, wenn der Transponder den höchsten Punkt der Bahn passiert, die axiale Position des Transponders als Maß für eine statische Verformungskomponente bestimmt. Während einer Umdrehung des Rotorblattes wird mit der Inertialsensorik die axiale Beschleunigung des Transponders erfasst und durch zweifache zeitliche Integration eine dynamische Verformungskomponente berechnet. Aus der Summe der statischen und der dynamischen Verformungskomponenten kann für jeden Zeitpunkt die Gesamtverformung berechnet werden.
