Method of adjusting rotor blade of wind generator

摘要

The method involves turning rotor blades simultaneously about their longitudinal axis, so that the rear blade edges are turned into the wind. Each blade is then turned back separately into a flag position, while the rotor is braked by the remaining blades, so that no excessive rotor speed is reached. The remaining blades are then turned back one after the other in the same way. The beginning of the turning back is synchronised with the rotor position.
