Title
(DE) VERFAHREN ZUM STEUERN EINER WINDENERGIEANLAGE
(EN) METHOD FOR CONTROLLING A WIND TURBINE
(FR) PROCÉDÉ PERMETTANT DE COMMANDER UNE ÉOLIENNE
Abstract
(DE)
Es wird ein Verfahren zum Steuern einer Windenergieanlage (100) bei einem Start oder Anfahren der Windenergieanlage (100), bevor die Windenergieanlage (100) an ein elektrisches Versorgungsnetz angeschlossen ist oder bevor die Windenergieanlage (100) wieder an das elektrische Energieversorgungsnetz angeschlossen wird, vorgesehen. Die Windenergieanlage (100) weist einen Rotor (106) mit einer Rotorarretierung (300), mindestens ein Rotorblatt (200, 201 – 203) und mindestens einem Blattwinkelerfassungssensor (600) für jedes Rotorblatt zum Erfassen des Blattwinkels des Rotorblatts (200) auf. Der Blattwinkel des mindestens einen Rotorblattes (200, 201 – 203) wird mittels des Blattwinkelerfassungssensors (600) erfasst. Eine Entriegelung der Rotorarretierung (300) wird solange blockiert, bis sich der erfasste mindestens eine Blattwinkel innerhalb eines vorgegebenen Winkelbereichs befindet. Damit kann sichergestellt werden, dass die Rotorarretierung lediglich dann gelöst wird, wenn sich die Blätter beispielsweise in der Fahnenstellung befinden.
(EN)
Provided is a method for controlling a wind turbine (100) when starting or running up the wind turbine (100) before the wind turbine (100) is connected to an electric supply network or before the wind turbine (100) is re-connected to the electric power supply network. The wind turbine (100) comprises a rotor (106) having a rotor locking means (300), at least one rotor blade (200, 201 – 203) and at least one blade angle detecting sensor (600) for each rotor blade for detecting the blade angle of the rotor blade (200). The blade angle of the at least one rotor blade (200, 201 – 203) is detected by means of the blade angle detecting sensor (600). Unlocking of the rotor locking means (300) is blocked until the at least one blade angle detected lies within a predefined angular range. It is therefore possible to ensure that the rotor locking means is released only when the blades are, for example, in the feathered position.
(FR)
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.
