NºPublicación: EP3569859A1 20/11/2019

Solicitante:

LABORELEC CVBA [BE]

Resumen de: EP3569859A1

The invention relates to wind turbine efficiency improvement methods, related software, computer systems and arrangements including those. The invention provides wind turbine efficiency improvement (support) methods, related software, computer systems and arrangements including those related to the wind sensor orientation misalignment and/or integrated wind turbine control methods and systems based thereon. The invention leverages on the observation that ideally a wind turbine has a maximum (power) performance when the axis of its rotor is parallel with the wind direction, hence for a wind direction measurement, relative to said axis, being zero. However when the wind orientation sensor is (systematically) misaligned with respect to the axis, when observing a curve defined as the wind turbine performance versus wind orientation, such maximum (power) performance will occur at an offset value, indicative for said misalignment. It is an objective of the present invention to provide a method for determining the misalignment of the wind orientation sensor attached to a wind turbine with respect to the axis of the rotor of said wind turbine and using said method to determine the wind orientation for which a maximum wind turbine performance is obtained.
