Problems solved by technology

Therefore, the wind reaching the wind sensor unit arranged in the rear upper part of the nacelle is in fact turbulent and disturbed by the rotor blades at any time, so that even the filtering of the measurement data mentioned above cannot remove the blade disturbances
Therefore, the obtained values ​​of wind speed and direction are in fact imprecise

Embodiment Construction

[0038] The illustrations in the figures are schematic. Note that in different figures, similar or identical elements are provided with the same reference signs or with reference signs that differ only in the first digit.

[0039] figure 1 A wind turbine 100 according to an embodiment of the invention is shown. More specifically, wind turbine 100 includes tower 105 that holds rotor 110 , nacelle 120 , rotating generator section 130 , and wind sensor 140 . A rotor or hub 110 includes rotor blades 112 , 114 and 116 . A platform 122 and a cooling device 124 are arranged on top of the nacelle 120 as is known in the field of direct drive wind turbines. The rotary generator portion 130 is arranged between the rotor 110 and the nacelle 120, and is composed of a tubular member equipped with magnets on its inner wall. The wind sensor 140 is held by a retaining member (not shown, see Figure 2 to Figure 5 )Keep. The holding member is fastened to the nacelle 120 by beams 161 , 162 a...

Abstract

There is described a wind turbine (100) comprising a rotor (110), a nacelle (120), a generator, and a wind sensor (140, 142, 144), wherein the wind sensor is arranged above a part (130) of the generator that extends between the rotor (110) and the nacelle (120). Furthermore, a wind farm comprising a plurality of interconnected wind turbines (100) is described. Yet further, a method of assembling or modifying a wind turbine (100) is described.

Description

technical field [0001] The invention relates to the field of electrical energy production devices, in particular wind turbines. More specifically, the invention relates to a wind turbine comprising a rotor, a nacelle, a generator and wind sensors. Furthermore, the invention relates to a wind park comprising a plurality of wind turbines. Still further, the invention relates to a method of assembling or retrofitting a wind turbine. Background technique [0002] Wind speed and wind direction are important parameters for operating a wind turbine. Wind speed is for example used to set the load and / or blade angle (pitch) of the wind turbine during operation and wind direction is used to adjust the direction of the wind turbine relative to the wind (yaw angle). [0003] Traditionally, wind parameter values ​​are obtained by wind sensor units arranged on the nacelle roof as far as possible from the rotor, ie at the rear end of the nacelle, in order to minimize measurement disturb...
