Meßeinrichtung zur Prüfung und Vermessung von Turm und Rotor von WindenergieanlagenMeasuring device for testing and measuring the tower and rotor of wind turbines

Üblicherweise beschränkt sich die Prüfung von Turm und Rotor einer Windenergieanlage auf eine Sichtkontrolle sowie das Abklopfen der Konstruktion, wobei nur offensichtliche äußere Fehler wie Risse und Korrosionserscheinungen bzw. sehr grobe innere Fehler z.B. Holmablösungen ermittelt werden können. Der Aufwand für diese Art der Prüfung ist sehr hoch, da die Anlage währenddessen abgeschaltet werden muß, eine Hebebühne und entsprechend mehrere Personen benötigt werden.Usually, the inspection of the tower and rotor of a wind turbine is limited to a visual inspection and tapping of the structure, whereby only obvious external defects such as cracks and signs of corrosion or very serious internal defects such as spar detachments can be identified. The effort required for this type of inspection is very high, as the system has to be switched off during the inspection and a lifting platform and several people are required.

Ähnlich hoch ist auch der Aufwand zur Ermittlung der Anstellwinkel der Rotorblätter. Dazu wird eine manuell an der Blattspitze angebrachte Schablone vom Boden aus mit Hilfe eines Theodoliten vermessen. Eine Veränderung des Anstellwinkels unter Betriebsbedingungen kann so nicht ermittelt werden.The effort required to determine the angle of attack of the rotor blades is similarly high. To do this, a template manually attached to the tip of the blade is measured from the ground using a theodolite. A change in the angle of attack under operating conditions cannot be determined in this way.

Um eine Materialermüdung festzustellen, müßte das Blatt demontiert und im horizontal eingespannten Zustand untersucht werden, was wirtschaftlich nicht zu realisieren ist.In order to determine material fatigue, the blade would have to be dismantled and examined in a horizontally clamped state, which is not economically feasible.

Durch die Entwicklung zu immer leistungsstärkeren Windenergieanlagen steigt der Bedarf nach einer optimierten Grundeinstellung der Rotorblätter, um den Energieertrag der Anlage zu gewährleisten sowie nach einer gesicherten Lebensdauerprognose, um Schaden durch Bauteilversagen zu verhindern.Due to the development of ever more powerful wind turbines, the need for an optimized basic setting of the rotor blades is increasing in order to guarantee the energy yield of the system as well as for a reliable service life forecast in order to prevent damage due to component failure.

Mit der hier vorgeschlagenen Meßeinrichtung lassen sich beide Aufgaben mit geringerem personellen und zeitlichen Aufwand während des normalen Betriebes der Anlage realisieren.
Dazu wird der Meßkopf (1) auf einem Stativ (2) am Boden vor der Windenergieanlage (3) aufgestellt. Der Meßkopf besteht aus einem Entfemungssensor (4), der elektromotorisch um eine vertikale (5) und eine horizontale Achse (6) geschwenkt werden kann. Die Bewegungen beider Achsen werden von der Bahnsteuerung (7) koordiniert und die aktuelle Lage des Entfernungssensors wird zusammen mit den gemessenen Entfernungen an die Auswerteeinheit (8) übergeben, die daraus die Lage des Meßortes (9) im Raum berechnet.With the measuring device proposed here, both tasks can be realized with less personnel and time expenditure during normal operation of the system.
For this purpose, the measuring head (1) is set up on a tripod (2) on the ground in front of the wind turbine (3). The measuring head consists of a distance sensor (4) that can be swiveled around a vertical (5) and a horizontal axis (6) by an electric motor. The movements of both axes are coordinated by the path control (7) and the current position of the distance sensor is transferred together with the measured distances to the evaluation unit (8), which uses this to calculate the position of the measuring location (9) in space.

Die nicht mitbewegte Reflexionslichtschranke (10) ermöglicht die genaue Feststellung der Blattdurchgänge und der Rotordrehzahl. Mit Hilfe dieser Daten kann die Auswerteeinheit eine Synchronisation zwischen den Bewegungen des Entfernungssensors und des Rotors herstellen, um so die gezielte Verfolgung bestimmter Punkte auf einzelnen Rotorblättern zu gewährlei-The non-moving reflection light barrier (10) enables the precise determination of the blade passages and the rotor speed. Using this data, the evaluation unit can establish a synchronization between the movements of the distance sensor and the rotor, in order to ensure the targeted tracking of certain points on individual rotor blades.

sten. Dadurch ist eine Ermittlung des Schwingungsverhaltens der Rotorblätter möglich, das in direktem Zusammenhang zur Material- bzw. Bauteilermüdung steht.This makes it possible to determine the vibration behavior of the rotor blades, which is directly related to material or component fatigue.

Werden zusätzlich die Daten der mobilen Wetterstation (11) und der Leistungsmessung (12) erfaßt, so können auch Aussagen zu Einstellungen und zum Verhalten der einzelnen Bauteile in Abhängigkeit von der Belastung der Windenergieanlage getroffen werden.If the data from the mobile weather station (11) and the power measurement (12) are also recorded, statements can also be made about the settings and behavior of the individual components depending on the load on the wind turbine.
