Embodiment Construction

[0034] figure 1 The top view of the rotor 1 shows part of the rotor 1 with the hub 2 and one rotor blade 4 of all three rotor blades of the rotor 1 . The rotor blades 4 are fastened to the hub by means of blade adapters 6 . In this case, the blade adapter 6 is fastened rotatably on the hub 2 in order to rotate the rotor blade 4 in windward, leeward or in an intermediate position. Furthermore, a wind measuring device 20 for measuring the wind prevailing in the region of the hub 2 is shown.

[0035] An arrow indicating the direction of the wind which acts to a certain extent on the rotor blades is marked with the reference number 8 . Here, the wind direction corresponds to the figure 2 The viewing direction of the view of the wind energy plant. figure 2 An overall view of a wind energy installation 10 is shown schematically, and here an aerodynamic rotor 1 with all three rotor blades 4 is shown. In addition, a wind energy installation tower 12 is shown.

Abstract

The present invention concerns a method of operating a wind power installation, wherein the wind power installation has an aerodynamic rotor in the form of a horizontal-axis rotor having a hub with at least one rotor blade, and provided on the rotor is at least one load measuring means for detecting a wind loading on the rotor, the method includes the steps: rotating the rotor of the wind power installation without or with a slight wind loading for calibration of the load measuring means and in that case recording a load measurement with the load measuring means, and calibrating the load measuring means based on the load measurement and previously known weight forces occurring at the rotor.

Description

technical field [0001] The invention relates to a method for operating a wind energy installation and to a wind energy installation. Background technique [0002] A wind energy installation with a rotor with a horizontal axis has at least one, usually three, rotor blades which are conventionally rotated about a horizontal axis by the wind blowing thereon in order to generate electrical energy by means of the rotational movement. If the wind blowing against the rotor blades is too strong, the wind energy installation can - depending on the frequency and intensity - be damaged. Due to the at least partial rotation of the rotor blades against the wind, such loads can be experienced, for example, due to excessive wind. This is also called pitching. [0003] In order to be able to introduce such or other measures for relieving the load on the wind energy installation, it is necessary to detect the corresponding load due to strong winds. Continuously strong and uniform winds ca...
