Blade angle adjustment rate limit adjustment

摘要

A method for the operation of a wind power plant (11) with a rotor (9), which has at least one rotor blade (10), wherein at least one part of the rotor blade (10) will be or is rotated around a longitudinal axis of the rotor blade (10) by a blade angle () wherein the rotation of the at least one part of the rotor blade (10) occurs with a pre-settable blade angle adjustment rate (θ), wherein the rotor (9) is operated speed variably and wherein the blade angle adjustment rate () is restricted by a pre-settable blade angle adjustment rate limit (G, G′, G1-G4). Furthermore, a wind power plant (11) with a rotor (9), which receives at least one rotor blade (10), wherein at least one part of the rotor blade (10) is rotatable around a longitudinal axis of the rotor blade (10) by a blade angle (), wherein a blade angle adjustment rate is pre-settable and the blade angle adjustment rate () is restricted by a blade angle adjustment rate limit (G, G′, G1-G4).

1. A method for the operation of a wind power plant (11) with a rotor (9), which has at least one rotor blade (10), comprising the steps of:
rotating at least one part of the rotor blade (10) around a longitudinal axis of the rotor blade (10) by a blade angle (), wherein the rotation of the at least one part of the rotor blade (10) occurs with a pre-settable blade angle adjustment rate (), wherein the rotor (9) is operated speed variably and wherein the blade angle adjustment rate () is restricted by a pre-settable blade angle adjustment rate limit (G, G′, G1-G4), and wherein a variable blade angle adjustment rate limit (G, G′, G1-G4), is changed depending on at least one operating parameter of the wind power plant (11) wherein via a blade angle adjustment rate limit adjustment limit, a value of the adjustment rate of the blade angle adjustment rate limit (G) is reduced or restricted.
