BeschreibungDescription

Titel: Eissensor für WindenergieanlagenTitle: Ice sensor for wind turbines

Das hier vorgestellte System dient der Erkennung von Eisansatz an Rotorblättern von Windenergieanlagen. Die Sensoren erfassen, im Gegensatz zu den bisherigen Systemen, die Ist-Vereisung jedes einzelnen Rotorblattes.The system presented here is used to detect ice buildup on the rotor blades of wind turbines. In contrast to previous systems, the sensors record the actual icing of each individual rotor blade.

Moderne Anlagen verfügen i.d.R. über Vorrichtungen, die die Anlagen bei Eisansatz stilllegen oder durch ein Beheizen der Rotorblätter den Eisansatz minimieren bzw. verhindern. Die derzeitige Erfassung ob Eisansatz an den Rotorblättern vorliegt erfolgt durch die Aufnahme der metrologischen Umweltbedingungen. Dieses Verfahren ist jedoch von einer hohen Unsicherheit geprägt.Modern systems usually have devices that shut down the system when ice forms or that minimize or prevent ice formation by heating the rotor blades. The current method of determining whether ice is forming on the rotor blades is to record the metrological environmental conditions. However, this method is characterized by a high degree of uncertainty.

Das hier angemeldete System erfasst die an jedem Blatt anliegenden mit Hilfe geeigneter Sensoren (1) im Rotorblatt den realen Eisansatz. Als Sensoren bieten sich z.B. optische, induktive etc. Sensoren an. In Kombination mit den metrologischen Umweltdaten kann eine zuverlässige Erfassung von relevanten Eisansatz an jedem einzelnen Rotorblatt erfolgen. Auf diese Weise kann das Gefahrenpotential durch Eisabwurf auf ein vertretbares Minimum reduziert werden bzw. unnötige Stillstandzeiten von den Anlagen vermieden werden. Gleichzeitig bietet dieses System dem Betreiber die Möglichkeit die Unregelmäßigkeit des ordnungsgemäßen Betriebs zu dokumentieren.The system registered here records the actual ice buildup on each blade using suitable sensors (1) in the rotor blade. Suitable sensors include optical, inductive, etc. sensors. In combination with the metrological environmental data, relevant ice buildup on each individual rotor blade can be reliably recorded. In this way, the risk potential from ice shedding can be reduced to a reasonable minimum and unnecessary downtimes of the systems can be avoided. At the same time, this system offers the operator the opportunity to document irregularities in proper operation.

Die Erfassung des Eisansatzes erfolgt in der Nähe der Rotorblattspitzen, dadurch ist gewährleistet, dass die Datenerfassung in dem Bereich erfolgt, indem i.d.R. sich vorrangig Eis ansetzt. Die erfassten Daten werden über entsprechende Datenleitungen (2) in das Maschinenhaus der Anlagen geleitet, wo sie unter Berücksichtigung der metrologischen Rahmenbedingungen in entsprechenden Datenverarbeitungseinheiten (3) soweit aufgearbeitet werden, dass die erforderlichen Maßnahmen ergriffen werden können.The ice buildup is recorded near the tips of the rotor blades, which ensures that the data is recorded in the area where ice usually forms. The recorded data is sent via appropriate data lines (2) to the turbine's machine room, where it is processed in appropriate data processing units (3) taking the metrological conditions into account so that the necessary measures can be taken.

Claims (1)

Integration von geeigneten Messsensoren in einem oder mehreren Rotorblättern, an einer oder mehreren Stellen, zur Erfassung des Vereisungsgrades jedes einzelnen Rotorblattes.
