METHOD AND DEVICE FOR REDUCING A PITCHING MOMENT WHICH LOADS A ROTOR OF A WIND POWER PLANT

摘要

A method for reducing a pitching moment that loads a rotor of a wind power plant includes determining a manipulated variable in order to set an azimuth angle of the wind power plant. A horizontal oblique incoming flow against the rotor is brought about by a wind acting on the rotor by use of the azimuth angle so as to reduce a portion of the pitching moment that is caused by vertical wind shear acting on the wind power plant.
