Embodiment Construction

[0028] The description in the drawings is schematic. Note that in different diagrams, the same drawing markers are provided to similar or identical features.

[0029] Figure 1 Illustrated according to the present invention of a wind turbine 1. Wind turbine 1 includes a tower mounted on an undescribed base 2. Cabin 3 is arranged on top of Tower 2. Wind turbine 1 further includes a wind rotor having at least one blade 4 (in Figure 1 In an embodiment, the wind rotor comprises three blades 4, wherein only two blades 4 are visible). Wind rotor 5 rotates around the hinge axis Y. Blade 4 is substantially radial with respect to the hinge Y and extends along the corresponding longitudinal axis X.

[0030] Wind turbine 1 includes a generator 11, the generator 11 includes a stator 20 and a rotor 30. Rotor 30 with respect to the stator 20 may be rotated around the hinge Y. Wind rotor 5 direct (e.g. direct drive) or with the help of a rotatable spindle 9 and / or via a gearbox ( Figure 1 N...

Abstract

A method of controlling a wind turbine (1) comprises the step of boosting an output power of the wind turbine above a nominal power (Pw) of the wind turbine according to a boost operating function (110, 120, 130) representative of a boost level of the wind turbine (1). The boost operating function (110, 120, 130) is a progressive function of the operating variable at least between a first threshold value (Tv1, Tv1 ', Tv1' ') and a second threshold value (Tv2, Tv2') of the operating variable.

Description

Technical field [0001] The present invention relates to a control of a wind turbine for power increase or increase the nominal power of a wind turbine above the nominal power of a wind turbine. [0002] Technical background [0003] Wind turbines can provide a power boost, i.e., there is a possibility of increasing the power beyond the nominal power value. The speed increases with the power. The boost is configurable and can be set to 5% of the nominal power by default. If generator and converter capacity allows this, the power boost can be increased to a higher amount, such as 10% of the nominal power. This overcapacity can be used, for example, to increase power in strong winds. [0004] According to possible known embodiments, when the pitch angle (pitch angle) and wind speed reach above a predetermined threshold, the power increase in power generation is gradually increased. This is done to ensure that, in the case of most extreme load drive components designs, the power is n...
