Definitions
- an operating parameter of a wind turbine in particular the power produced by it, is used for ice detection as a function of boundary conditions such as a wind speed. speed is recorded and compared with previously known values for this operating parameter. This is based on the knowledge that ice accumulation leads to a reduction in the output of the wind turbine. If the power actually produced by this system is known at a given wind speed, a comparison of the power currently supplied with a known wind speed can indicate ice formation. In order to be able to carry out the procedure with sufficient informative value, comparative values of the system in question are required.
- a "high probability" of recognizing the absence of ice is understood to mean a probability of more than about 80%, for example, within the scope of the registration.
- FIG. 5 shows a flow chart of a method for training a device for detecting ice accumulation on a rotor blade.
- FIG. 1 a sectional drawing of a part of a wind energy plant 1 is shown as an example, which has a device 6 for detecting ice accumulation on a rotor blade.
- the wind energy installation 1 shown in FIG. 1 is suitable and set up for carrying out a teaching method for the device 6 according to the application.
- the device 6 is also referred to below as an ice detection device 6 .
- the ice detection device 6 for detecting an accumulation of ice on one or more of the rotor blades 41 comprises at least one vibration sensor 61 , hereinafter referred to as sensor 61 for short.
- the two sensors 61 shown in FIG. 1 are arranged approximately in a lower third of the rotor blade 41 .
- the sensors 61 can However, it can also be arranged at other positions in the rotor blade 41 .
- the expected power of the wind energy plant 1 can be estimated from the model generated in step S1 on the basis of the operating and environmental conditions measured in step S2.
- step S4 a difference between the power actually measured and the power expected is determined, preferably as a ratio, possibly in other ren embodiments as a difference.
- the ratio corresponds to the efficiency e of the wind turbine shown in FIG.
- step S4 the determined efficiency e is compared with a predefined threshold value eo. Possible limit values are in the range of about 60 - 95%. Falling below the threshold value eo indicates that the rotor blades 41 are not free of ice.
- the method branches back to step S2 in order to determine operating parameters again and carry out a power measurement. Since the absence of ice does not change within a very short time, a pause of, for example, a few hours can be provided before the method continues with the steps S2 ff. repeated.
- step S6 it is then checked whether reference spectra are available in sufficient number and quality for a sufficiently large range of operating and environmental conditions. If this is not the case, the method branches back to step S2 again in order—again, possibly after a waiting time—to be able to record further reference spectra under different operating and environmental conditions. If it is determined in step S6 that a sufficiently large and qualitatively suitable set of reference spectra is present, the training phase for the monitoring device 6 is complete and the monitoring device 6 can be operated in the regular monitoring mode in a step S7.

Abstract
L'invention concerne un procédé d'entraînement d'un dispositif (6) d'identification d'une accumulation de glace sur au moins une pale de rotor (41) d'une éolienne (1). Ledit procédé comprend les étapes suivantes : la détermination des conditions de fonctionnement et d'environnement pendant le fonctionnement de l'éolienne (1) ; la détermination d'une sortie électrique de l'éolienne (1) qui doit être attendue dans les conditions de fonctionnement et d'environnement déterminées ; la mesure d'une sortie électrique qui est réellement générée par l'éolienne (1) ; la comparaison de la sortie électrique attendue de l'éolienne (1) avec la sortie électrique réellement générée par celle-ci ; en fonction du résultat de la comparaison, la détermination avec un niveau élevé de probabilité que l'au moins une pale de rotor (41) est exempte de glace ; et la détection des vibrations de ladite au moins une pale de rotor (41), la dérivation des propriétés caractéristiques des vibrations et le stockage des propriétés caractéristiques en tant que référence pour le dispositif (6) pour identifier une accumulation de glace si, dans la comparaison, il a été déterminé avec un niveau élevé de probabilité que l'au moins une pale de rotor (41) est exempte de glace. L'invention concerne également un dispositif permettant d'identifier une accumulation de glace sur au moins une pale de rotor d'une éolienne (1), ledit dispositif étant conçu pour mettre en œuvre un tel procédé.
