Description
Der Beschreibungstext wurde nicht elektronisch erfaßt
Claims (1)
- Durch die Integration von geeigneten Sensoren in einem oder mehreren Rotorblättern einer Windenergieanlage, kann die Energieaufnahme der einzelnen Rotorblätter ermittelt werden.
Auf Basis dieser Daten kann eine gezielte Verstellung des Pitch-Winkels zur Beeinflussung der Energieaufnahme eines jeden einzelnen Rotorblattes vorgenommen werden. Hierdurch kann die Krafteinleitung in den Antriebsstrang der Windenergieanlage über die gesamte überstrichene Fläche gleichmäßiger verteilt werden.
