Embodiment Construction

[0091] figure 1A wind energy installation 100 is shown with a tower 102 and a nacelle 104 . A rotor 106 with three rotor blades 108 and a spinner 110 is arranged on the nacelle 104 . In operation the rotor 106 is set in rotational motion by the wind thereby driving a generator in the nacelle 104 .

[0092] figure 2 A detail of a wind energy installation 200 with a nacelle 202 and a generator 204 is shown schematically. The generator 204 has a stator 206 and a rotor 208 . Rotor 208 is directly coupled to three rotor blades 210 , which are only partially and only schematically shown and only two of them are shown, since the third rotor blade is in the position shown in the position of nacelle 202 . on the side facing away.

[0093] The generator 204 is thus formed as an inner rotor and since the rotor 208 is directly connected to the rotor blades 210 and thus to the aerodynamic rotor 212 , there is a wind turbine without a transmission. Rotor 208 then rotates during opera...

Abstract

The invention relates to a method for operating a wind turbine, and the wind turbine comprises a generator, having a generator axis, for generating electrical power from wind, a nacelle for supporting the generator, and a tower, having a tower axis, for supporting the nacelle. The method comprises the following steps: detecting at least one tower vibration using a vibration sensor; detecting a mechanical generator vibration triggered by at least one electrical fault using the same vibration sensor; and controlling the wind turbine on the basis of the detected tower vibration and the detected generator vibration.

Description

technical field [0001] The invention relates to a method for detecting multiple vibrations of a wind energy installation. The invention also relates to a method for operating a wind energy installation, in which a plurality of vibrations is detected. Furthermore, the invention relates to a wind energy installation. Background technique [0002] Wind power plants are known which generate electrical power from the wind. However, disturbances may occur during the operation of such a wind energy installation, which are monitored for the protection of the wind energy installation. Possible disturbances are excessive vibrations of the tower, ie in the area of ​​the tower top and thus in the area of ​​the gondola of the wind energy installation mounted on the tower top. Such vibrations can be generated by the excitation of the wind at the corresponding resonant frequency and thus reach high amplitudes, so that the wind energy installation must be at least partially shut down in ...
