Abstract

Two independent adjusting systems are recommended for each rotor blade (6) for blade angle adjustments of the rotor blades (6) of the rotor of a wind power plant, assuring full redundancy of the blade angle adjustment. By suitable control of the individual adjustment paths of the two adjustments systems, additional advantageous effects can be gained, such as good lubricant distribution and/or even load distribution over time (FIG. 1).
