  • METHOD AND SYSTEM FOR WIND VELOCITY FIELD MEASUREMENTS ON A WIND FARM
    Publication number: 20130317748
    Abstract: A method and system is provided for determining a wind velocity field on a wind farm having of a plurality of spatially distributed wind turbines (10). The method and system acquires data via measurement instruments (20, 22) that convey energy along respective paths (30) between selected pairs of turbines (10) and acquire data from the conveyed energy. From the acquired data, a wind velocity field is determined.

  • Load mitigation device for wind turbine blades
    Patent number: 8251657
    Abstract: The present invention includes a rotor blade (20) having a blade body (30) with a leading edge (26) and a trailing edge (28) and opposed first and second surfaces (34, 36) extending there between defining an airfoil shape (32) in cross-section. A passageway (42) extends through the blade body (30) between the first and second surfaces (34, 36). A flexible member (60) is sealed over one end (50) of the passageway (42). Advantageously, the flexible member (60) is passively responsive to changes in a differential pressure between the first and second surfaces (34, 36) to move between a deactivated position (62) and an activated position (64) where the flexible member (60) extends away from the airfoil shape (32) to function as a load mitigation device (40) for the wind turbine rotor blade (20).
