Abstract
The invention relates to a method and a system for regulation of the rotational speed (52) of a rotor on a wind energy unit with a generator and a rotor blade. The first set parameter is a pitch angle (Pitch) of the rotor blade and the second set parameter is the torque of the generator. The system comprises a pitch angle control or regulation device (32), a torque control or regulation device (33), a first device for determination of a first rotational speed set value (28) (first rotational speed set value determination device (29)) and a second device (26) for determination of a second rotational speed set value (29) (second rotational speed set value determination device (26)). The first rotational speed set value (28) may be supplied to the pitch angle control or regulation device (32) and the second rotational speed set value (29) may be supplied to the torque control or regulation device (33), wherein the first and second rotational speed set value (28, 2)) may be different from each other.
