Definitions

  • the present invention relates to a method for controlling a wind energy installation when the wind energy installation is started or started, a mobile control unit and a wind energy installation.
  • the wind turbine In normal operation, the wind turbine is connected to an electrical supply network and supplies electrical energy to the supply network. However, if there is no wind, the wind turbine itself may take electrical energy from the energy supply network in order to maintain its operation.
  • the wind energy installation is typically not yet connected to the electrical energy supply network when it is being set up and therefore cannot draw any energy from the supply network in order to control the wind energy installation.
  • a so-called assembly aid can be provided, for example, to control the wind energy installation while it is not connected to the electrical energy supply network.
  • This assembly aid can have an electrical power supply and a control unit.
  • the German Patent and Trademark Office researched the following documents: EP 2 905 467 A1, DE 10 2008 022 383 A1, DE 10 2010 039 628 A1, DE 10 2010 037 695 A1, DE 10 2013 004 580 A1 and EP 2 963 287 A1.
  • a method for controlling a wind energy installation when the wind energy installation is started up or started up is thus provided before the wind energy installation is connected to an electrical supply network or before the wind energy installation is reconnected to the electrical energy supply network.
  • the wind power plant has a rotor with a rotor lock, at least one rotor blade and at least one blade angle detection sensor for each rotor blade for detecting the blade angle of the rotor blade.
  • the blade angle of the at least one rotor blade is detected by means of the blade angle detection sensor. Unlocking of the rotor lock is blocked until the detected at least one blade angle is within a predetermined angular range. This can ensure that the rotor lock is only released when the blades are in the flag position, for example.
  • the blade angle detection sensor can have inductive sensors and position gauges.
  • the blade angle can also be recorded using any other sensors.
  • FIG. 1 shows a schematic illustration of a wind energy installation according to one aspect of the present invention

  • the wind turbine 100 has a tower 102 with a nacelle 104 and an aerodynamic rotor 106.
  • the aerodynamic rotor 106 has at least one rotor blade 200, 201-203.
  • the blade angle of the rotor blades 200, 201-203 can be set, for example, by means of a pitch motor, not shown.
  • a rotor brake 400 can optionally be provided, which serves to be able to brake the aerodynamic rotor 106.

  • a blade angle detection sensor 600 with, for example, two sensors 610 and two position gauges 620 can be provided in the region of a rotor blade root of the blade 203.
  • the two other rotor blades 201, 202 can also have a corresponding blade angle detection sensor 600.

  • the blade angle detection unit 500 can summarize the blade angle information of the three rotor blades 201-203. The summarized information can be forwarded to a construction aid 700.
  • the assembly aid 700 can be used in particular when the wind energy installation is being installed and the wind energy installation is not yet connected to the electrical energy supply network. As an alternative to this, the assembly aid 700 can be used according to the invention after the wind energy installation has been serviced and the wind energy installation has been disconnected from the supply network
  • the assembly aid 700 which represents a mobile control unit, can be used to control certain functions of the wind energy installation 100, for example the blade angle adjustment.
  • the brake 400 and the rotor lock 300 can be connected to the mobile control unit 700, or the mobile control unit 700 receives information relating to the operation of the brake 400 and the rotor lock 300.

  • the rotor lock 300 can optionally have an electromagnetic valve 310 and a plurality of bolts 320, which can be inserted or removed in recesses 330 in the rotor in order to lock or release the rotor.
  • the rotor lock can also be carried out in another way.
  • the mobile control unit (assembly aid) 700 is designed, particularly when the wind energy installation has been disconnected from the energy supply network, to block an unlocking of the rotor lock until the mobile control unit 700 receives corresponding blade angle information from the control unit 500.
  • the rotor lock 300 is only unlocked or deactivated when the three rotor blades 201-203 are in a desired position, for example the flag position.
  • the brake 400 can also be released when the control unit 500 notifies the mobile control unit 700 that the blade angles of the rotor blades 201-203 are in the desired position. While the rotor blades in FIG. 2 are in the flag position, the rotor blades according to FIG. 3 have a blade angle of ⁇ 90 °.
  • the blade angles of the three rotor blades 201-203 are not in the desired range and the control unit 500 passes this information on to the mobile control unit 700, so that the rotor lock 300 and / or the brake 400 cannot be released.
  • 4 and 5 each show a schematic representation of the functional groups of a wind power plant according to a second exemplary embodiment of the invention. While the first exemplary embodiment relates to a mobile control unit 700, the second exemplary embodiment describes how the method according to the invention is solved with the fixed and central gondola control unit 800.
  • the rotor blade 203 is shown in the 90 ° position, so that the connection box / control unit 500 can transmit a corresponding signal via a rotor subdistribution 106a, via a slip ring transmitter 90 to a nacelle control unit 800.
  • the nacelle control unit 800 can be coupled to a stator unit 950, which in turn can be coupled to a rotor brake 400 and the rotor lock 300.
  • the brake 400 and the rotor lock 300 correspond to the brake 400 and the rotor lock 300 according to the first exemplary embodiment.

  • the stator unit 950 cannot release the rotor lock or the brake 400 since the rotor blades 200 do not have the desired blade angle.

Abstract

L'invention concerne un procédé permettant de commander une éolienne (100) lors d'un lancement ou démarrage de l'éolienne (100) avant que l'éolienne (100) ne soit raccordée à un réseau d'alimentation électrique ou avant que l'éolienne (100) ne soit à nouveau raccordée au réseau d'alimentation en énergie électrique. L'éolienne (100) comporte un rotor (106) pourvu d'un arrêt (300) de rotor, au moins une pale (200, 201 - 203) de rotor, et au moins un capteur de détection (600) d'angle de pale pour chaque pale de rotor, servant à détecter l'angle de pale de la pale (200) de rotor. L'angle de pale de la ou des pales (200, 201 - 203) de rotor est détecté au moyen du capteur de détection (600) d'angle de pale. Un déverrouillage de l'arrêt (300) de rotor est bloqué jusqu'à ce que l'angle ou les angles de pale détectés se trouvent dans une plage d'angles prédéfinie. Cela permet ainsi de garantir que l'arrêt de pale est alors seulement déclenché quand les pales se trouvent par exemple dans la position en drapeau.
