Definitions

  • the invention is concerned with protecting a wind turbine and its supporting structure against harmful vibrations and deflections caused ' by wind loading.
  • the phenomenon of harmful vibrations has been illustrated in the past by- bridges with large spans that eventually collapsed since they experienced a wind load at their natural bending frequency, resulting in very excessive ' and destructive deflections of the structure.
  • the invention is concerned with ' protecting a wind turbine of the horizontal type, i.e. with a horizontal or almost horizontal rotor shaft carrying one or more (e.g. four equally circumferentially spaced) radially extending rotor blades .
  • the substantially straight rotor blades which obviously revolve in a vertical or almost vertical plane, have a suitable airfoil and pitch to generate sufficient lift from the passing wind to generate a, tangential force to revolve the rotor shaft.
  • the rotor shaft is drivingly connected to an electrical generator, such that electrical energy is generated from the wind.
  • the rotor shaft, its bearings, the electrical generator and gearbox, if any, ' are typically housed in a nacelle.
  • the rotor shaft can swivel around a vertical or almost vertical axis such that the rotor blades can be oriented relative to the prevailing wind direction. . ⁇
  • this type of wind turbine is supported on top of a slender tower, e.g. a thin walled vertical steel tube. Typical dimensions range up to and above 80 meters height for the tower and 80 meters diameter for the rotor. Due to their large dimensions and elastic nature, such structures typically deflect back and forth in the wind, like the trunk of a tree.
  • the present invention proposes to change the aerodynamic drag at the top part of the tower, as soon as this phenomenon arises.
  • This can e.g. be done by changing the resultant of the collection of aerodynamic forces acting on or near the top of the tower, from e.g. one or more of the rotor blades.
  • the aerodynamic drag in the direction substantially upstream or downstream the prevailing wind direction is changed. Since this change is preferably actively changed, the inventors call the invention "Active Aerodynamic Damping", abbreviated to AM).
  • AAD can brake deflecting motion of the tower.
  • the invention will be further elaborated by the application of AAD to the rotor blades.
  • the pitch of one or a few or all of the rotor blades is changed in just the right way and at just the right time, e.g. during a tower deflection cycle.
  • the change in rotor thrust resulting from such pitch control can be used to damp and/or arrest the tower vibration.
  • the pitch of all rotor blades is substantially simultaneously (i.e. collectively) changed, preferably substantially over the same pitch angle, for the purpose of this ' invention.
  • the pitch of the rotor blade is changed towards stall.
  • the pitch of the rotor blade is changed as the tower deflects forward, i.e. in upstream direction compared to the prevailing wind direction.
  • the pitch of the rotor blade is changed temporarily for the purpose of this invention, e.g. only during a part of or one complete or a few revolutions of the rotor shaft.
  • This pitch control will be superimposed on the pitch control for regulating the maximum power output of the turbine (if present) .
  • the pitch control for regulating the maximum power output will be disabled when the pitch control for damping the tower vibration is triggered.
  • the pitch control according to the invention for damping the tower vibration will be called damping pitch control.
  • the damping pitch control will generally be caried out by some automatic control system, e.g. comprising a suitably programmed processing unit like a computer.
  • a control system ⁇ communicates with one or more sensors or detectors or other (input) means to be able to monitor the vibrating behaviour of the tower and/or obtain other parameters that are required for the damping pitch control.
  • the control- system can trigger the damping by a temporary blade pitch change.
  • use can be made of one or more accelerometers suitably mounted to e.g. the tower or nacelle or other part of the wind turbine and remotely or wired connected to the control system to provide the desired information about tower vibration/deflection.
  • strain gauges, inclination meters, speed sensors or acoustical or optical scanners e.g. a laser beam
  • the control system is designed such that damping pitch control is triggered when the monitored movement (vibration/deflection) of the tower exceeds a pre-determined level.
  • the control system can be designed to apply a time delay after receival of the triggering signal from such means, such that the damping pitch change takes place at just the right time.
  • Such time delay can be pre-determined or real-time calculated by the control system on the basis of e.g. actual rotor speed (for which the control system is connected to an input means for the rotor speed) .
  • Changing the blade pitch towards stall generally means that its angle of attack relative to the direction of the wind is increased. In other words, the inclination relative to the wind is increased. Thereby, the aerodynamic force from the wind on the blade is increased.
  • changing blade pitch towards stall thus will provide a braking force to the tower movement.
  • changing the blade pitch away from stall decreases the aerodynamic force from the wind on the blade.
  • changing blade pitch away from stall thus will lessen the contribution of the wind thrust to the tower movement.
  • damping pitch control starts with changing the blade pitch towards stall, preferably as soon as the tower starts deflecting upstream or thereafter, but before the tower starts deflecting downstream.
  • the blade pitch is preferably changed away from stall, preferably before the tower starts deflecting upstream agian (i.e. after having deflected downstream).
  • Changing the blade pitch away from stall is preferably such that the blade pitch is smaller compared to the blade pitch just before damping pitch control is triggered.
  • a presently preferred, non-limiting, example of the damping pitch control is as follows: While the wind turbine is operative, the tower is deflecting back and forth in a direction substantially parallel to the wind direction.
  • General blade pitch control may or may not be active to regulate the maximum power output of the wind generator.
  • Damping blade pitch control is inactive.
  • the accelerometer senses a maximum acceleration at maximum downstream tower deflection, exceeding the pre-determined level. This event triggers the damping pitch control (or other AAD) and disables or overrides the pitch control for regulating the maximum power output (if active) .
  • the rotor blades are rapidly controlled towards stall, increasing their pitch by 1.5 degrees, such that they brake the upstream deflection of the tower.
  • the rotor blades are controlled away from stall, decreasing their pitch by 3 degrees (thus 1.5 degrees compared to their pitch before damping pitch control was triggered) , such that the aerodynamic wind force on the rotor decreases.
  • This process of using increased blade pitch (increased aerodynamic drag) while deflecting upstream and decreased blade pitch . (decreased aerodynamic drag) while deflecting downstream is repeated as desired to reduce the tower vibration or deflection acceleration to an acceptable level . Then damping pitch control is disabeled and the pitch control 5 for ' regulating the maximum power output is enabled.
  • the accelerometer monitors the tower.
  • damping pitch control is only temporarily active, e.g. no longer than 5 minutes each time ' (or another predetermined time or number of deflection cycles of the tower) and preferably at a frequency of not more
  • the invention is applicable to all wind turbine types,
  • Invented are thus, i.a., .a method to control blade pitch to damp the tower deflection/vibration; a wind turbine provided with a system to control blade pitch to damp the tower deflection/vibration; and such a system.

Abstract

L'invention porte sur un procédé d'amortissement du mât d'une éolienne pendant son fonctionnement normal, qui, alors qu'on détecte que la flexion du mât atteint ou dépasse un niveau prédéterminé de sûreté modifie la traînée du sommet du mât. À cet effet on modifie le pas des pales, de préférence simultanément, et d'un même angle. Lorsque le mât fléchit vers l'amont, le pas tend vers la mise en drapeau. Lorsque le mât fléchit vers l'aval le pas s'écarte de la position en drapeau. L'éolienne est munie d'accéléromètres, de jauges de contrainte, d'inclinomètres, de détecteurs de vitesse, et de détecteurs acoustiques ou optiques qui communiquent avec un système automatique de commande pour mettre en œuvre le procédé d'amortissement.
