The invention relates to a wind power plant of greater power, wherein the rotor blades are adjusted in order to minimize the static and/or dynamic structural load, and/or in order to attenuate vibrations, such as due to the generation of counter-forces to forces and torques inhibiting compensation, even if a constant wind speed v8 does not require so, and to a method for operating such a wind power plant; for this purpose the invention provides to configure at least one rotor blade bearing as a rolling bearing, which is optimized for a high amount of overturns in that the entire dynamic axial load rating Ca,ges determined, according to DIN ISO 281, of all rows (µ) of a rolling bearing employed according to DIN ISO 281 and involved in the transmission of power in an axial direction corresponds to at least 1.5 times of the dynamic axial load rating Ca,ref according to DIN ISO 281 of a two-row rotary joint having comparable dimensions with regard to the surface of the bearing cross-section and the circumference at the center of gravity of the surface, and having identical spheres in both rows, and having an angle of support a of 45°; and/or in that the nominal service life L10 of a ball bearing employed, determined according to DIN ISO 281, corresponds to at least 3.375 times the service life L10,ref of a two-row rotary joint, calculated according to DIN ISO 281, having comparable dimensions with regard to the surface of the bearing cross-section and the circumference at the center of gravity of the surface, and having identical spheres in both rows, and having an angle of support a of 45°. |
