Problems solved by technology

However, the use of so-called pod anemometers is particularly inaccurate here and is also limited in that the operation of the wind energy installation interferes with the rotation of the measuring device, in particular the rotor, in which case Rotor blade passing measuring equipment
[0006] Furthermore, measuring devices on nacelles with wind energy plants often have the problem that the measuring devices are only able to determine the wind speed in the area of ​​the nacelle, but not in the entire area of ​​the rotor surface—that is, at the rotor blades in the wind energy plant In the area swept by during operation - determine the wind speed
As a result, detection of wind farms is often not feasible or only insufficiently feasible
[0007] Technically complex measurements such as ultrasonic measurements are also considered, but are very complex and cost-intensive

Embodiment Construction

[0068] figure 1 A wind energy installation 100 is shown with a tower 102 and a nacelle 104 . A rotor 106 with 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 .

[0069] figure 2 A wind farm 112 is shown with an exemplary three wind energy installations 100 , which may be identical or different. Three wind energy installations 100 therefore represent essentially any number of wind energy installations of wind park 112 . The wind energy installation 100 supplies its power, ie in particular the generated current, via an electrical wind park network 114 . In this case, the correspondingly generated currents or powers of the individual wind energy installations 100 are summed up and a transformer 116 is usually provided, which steps up and transforms the voltage in the wind park in order to then be fed in, also generally referred to as the PCC....

Abstract

The invention relates to a method for recording at least one measured value, wherein the measured value is recorded by means of at least one measuring drone (2), and the measuring drone (2) for recording the measured values flies into a predeterminable position, is held in the predeterminable position by a position controller, or the measuring drone's change relative to the predeterminable position is recorded, and the measuring drone records the at least one measured value and transmits the at least one recorded measured value or at least one value representative thereof to an evaluation unit(10) and / or stores said value.

Description

technical field [0001] The invention relates to a method for detecting at least one measured value, in particular for use in controlling a wind energy installation. Furthermore, the invention relates to a method for operating at least one wind energy installation based on at least one detected measured value. Furthermore, the invention relates to a surveying drone and a device for a plurality of surveying drones. Furthermore, the invention relates to a wind energy installation and a wind energy system having one or more wind energy installations. Background technique [0002] Wind power plants are known and used to generate electrical energy from the wind. For controlling a wind energy installation, it may at least be helpful to detect wind properties. These include in particular the wind speed and direction, which is also referred to below as wind value. Furthermore, it is helpful to detect, in particular during current operation, the acoustic emissions emitted by the w...
