摘要： Provided is a method for operating a wind turbine, an associated wind turbine and a wind park. The method comprises a) providing an indicator for the occurrence of a flow separation on a pressure side of a rotor blade of a rotor of the wind turbine, and b) changing an operational management of the wind turbine using the indicator, wherein the indicator comprises a pitch angle of the rotor blade. By using the pitch angle as an indicator, a flow separation on the pressure side of the rotor blade can be effectively prevented.

摘要： A method for operating a wind power installation is provided. The wind power installation comprises an aerodynamic rotor with rotor blades, where the rotor can be operated with a variable rotor rotation speed. The wind power installation outputs an output power generated from wind for feeding into an electrical supply grid. The wind power installation can be operated in a normal operating mode without power reduction and in a reduced operating mode with power reduction, in which a specified power reduced with respect to a rated installation power is specified. When operating in the reduced operating mode for wind speeds above a rated wind speed, at least in one rotation speed increase region, the wind power installation increases its rotor rotation speed as the wind speed rises further.

摘要： A method of controlling a wind power plant for generating electrical power from wind is provided. The plant comprises a rotor having rotor blades with adjustable blade angles and the rotor can be operated at a variable rotational speed. The method includes controlling the plant in a partial load mode when wind speed is below a nominal speed and, controlling the plant in a storm mode when the wind speed is above a storm commencement speed. An output power of the plant in the partial load mode and storm mode is adjusted according to an operating characteristic curve that determines a relationship between the rotational speed and the output power. A partial load characteristic curve is used as the operating characteristic curve for controlling the power plant in partial load mode, and a storm mode characteristic curve is used as the operating characteristic curve for controlling the plant in storm mode.

摘要： A method for operating a wind power installation having a rotor with rotor blades with an adjustable blade angle is provided. The installation is operated in a full-load mode for delivering a system-specific maximum power and in a partial-load mode for delivering a lower power, up to the system-specific maximum power. The installation in the partial-load mode operates according to choice in a normal mode or a limited mode, in each case based on an operating characteristic, which specifies a relationship between a rotational speed (n) of the rotor and the power to be delivered. A first operating characteristic is provided for operating the installation in the normal mode, and at least one second operating characteristic is provided for operating in the limited mode. The second operating characteristic provides a higher power for at least one rotational speed range than the first operating characteristic for the rotational speed range.

摘要： Provided is a method for adapting an operating characteristic of a wind power installation. The installation has a rotor with rotor blades having adjustable blade angles and operable with a variable rotor rotational speed. To control the installation, use is made of an operating characteristic which describes a relationship between the rotor rotational speed and an operating variable. The operating characteristic has a first portion with a first rotational speed range and a second portion with a second rotational speed range. The first rotational speed range has lower rotational speeds than the second rotational speed range, and the operating characteristic is adapted such that values of the operating variable of the first portion are increased values of the variable of the second portion are changed toward higher rotational speeds, and an expected total number of revolutions of the rotor over a predetermined lifetime of the installation remains approximately the same.
