Titel: Dynamische Pitch-Steuerung für WindenergieanlagenTitle: Dynamic pitch control for wind turbines
Das hier vorgestellte Steuerungssystem dient der dynamischen lastabhängigen Steuerung von Pitch-Systemen an Windenergieanlagen. Die Verstellung der Rotorblätter soll zielgesteuert unabhängig voneinander erfolgen, so dass jedes Rotorblatt den Anströmungswinkel so verändern kann, dass die Leistungsaufnahme bzw. -abgabe jedes einzelnen Blattes gleich groß ist.The control system presented here is used for the dynamic, load-dependent control of pitch systems on wind turbines. The adjustment of the rotor blades should be carried out independently of each other in a targeted manner so that each rotor blade can change the angle of flow so that the power input or output of each individual blade is the same.
Moderne Anlagen verfügen über immer größere Rotordurchmesser, derzeit sind Durchmesser von über 70m keine Seltenheit mehr. Hierdurch kommt es, aufgrund der Höhendifferenzen zwischen dem untersten und obersten Blatt, bereits zu relevanten unterschiedlichen leistungsbeeinflussenden metrologische Bedingungen. Da derzeitige Anlagen nur über ein zentrales Windmesssystem und / oder eine zentrale Leistungserfassung verfügen, kann die Leistungsaufnahme nicht einem einzelnen Blatt zugeordnet werden und somit auch nicht einzeln durch Verstellung der Blätter zielorientiert geregelt werden. Dieser Mangel führt zu ungünstigen Lasten innerhalb des Abtriebstranges sowie im Getriebe der Anlagen. Damit diese Lasten soweit wie möglich reduziert werden können, ist es erforderlich die Leistungsnahme jedes einzelnen Rotorblattes zu erfassen und anschließend durch direkte Verstellung des Pitch-Winkels soweit zu verändern, dass über die gesamte überstrichene Rotorfläche eine nahezu gleichbleibende Leistungsaufnahme erfolgt.Modern systems have ever larger rotor diameters; diameters of over 70m are no longer uncommon. Due to the height differences between the lowest and highest blades, this leads to relevant different metrological conditions that affect performance. Since current systems only have a central wind measurement system and/or a central power recording system, the power consumption cannot be assigned to a single blade and therefore cannot be controlled individually by adjusting the blades. This deficiency leads to unfavorable loads within the drive train and in the system's gearbox. In order to reduce these loads as much as possible, it is necessary to record the power consumption of each individual rotor blade and then change it by directly adjusting the pitch angle so that there is almost constant power consumption across the entire swept rotor area.
Das hier angemeldete System erfasst die an jedem Blatt anliegenden Strömungsgeschwindigkeiten, Druckunterschiede und / oder Spannungen mit Hilfe geeigneter Sensoren (1). Auf Basis dieser Daten kann der die Energieaufnahme jedes einzelnen Blattes rechnerisch ermittelt werden. Die daraus ermittelte Leistungsaufnahme der einzelnen Rotorblätter kann durch eine entsprechend schnell reagierende dynamische Pitch-Steuerung (2) so optimiert werden, dass alle Rotorblätter nahezu die gleiche Kraft in den Antriebsstrang eingeleitet wird.The system registered here records the flow speeds, pressure differences and/or tensions at each blade using suitable sensors (1). On the basis of this data, the energy consumption of each individual blade can be calculated. The resulting power consumption of the individual rotor blades can be optimized by a correspondingly fast-reacting dynamic pitch control (2) so that all rotor blades apply almost the same amount of force to the drive train.
Die Abnahme der Daten erfolgt in den bzw. an den Rotorblättern (3), dadurch ist gewährleistet, dass die Datenerfassung in dem Bereich erfolgt, indem die Leistungsaufnahme der Rotorblätter stattfindet. Die erfassten Daten werden über entsprechende Datenleitungen in das Maschinenhaus der Anlagen geleitet, wo sie in entsprechenden Datenverarbeitungseinheiten (4) soweit aufgearbeitet werden, dass die Pitch-Regelung in der Lage ist die erforderliche Verstellung der Rotorblätter vorzunehmen.The data is collected in or on the rotor blades (3), which ensures that the data is recorded in the area in which the power is consumed by the rotor blades. The recorded data is sent via appropriate data lines to the machine room of the system, where it is processed in appropriate data processing units (4) to such an extent that the pitch control is able to make the necessary adjustment of the rotor blades.
Claims (1)
Auf Basis dieser Daten kann eine gezielte Verstellung des Pitch-Winkels zur Beeinflussung der Energieaufnahme eines jeden einzelnen Rotorblattes vorgenommen werden. Hierdurch kann die Krafteinleitung in den Antriebsstrang der Windenergieanlage über die gesamte überstrichene Fläche gleichmäßiger verteilt werden. By integrating suitable sensors into one or more rotor blades of a wind turbine, the energy consumption of the individual rotor blades can be determined.
Based on this data, the pitch angle can be adjusted in a targeted manner to influence the energy absorption of each individual rotor blade. This allows the force introduced into the drive train of the wind turbine to be distributed more evenly across the entire swept area.
