Windkraftanlage: Anfahrvorgang simulieren

Beitragvon Fatih_MB am Fr 7. Nov 2014, 16:37

Hallo Leute,

ich arbeite gerade an meiner Semesterarbeit und bin fast am Ende. Ich muss nur noch den Anfahrvorgang simulieren. Ich arbiete mit dem Programm Mathcad.

Meine Aufgabenstellung lautet so:
Programmieren Sie einen Anfahrvorgang der Windenergieanlage, bei der die Anlage aus dem Stillstand (aus numerischen Gründen wird eine kleine Drehzahl von 0.1rpm als Stillstand definiert) auf eine Betriebsdrehzahl hochgefahren wird. Die Windgeschwindigkeit soll während dem Anfahrvorgang konstant bleiben. Das maximale Moment des Generators ist über der Drehzahl konstant und kann aus der Nennleistung und der Nenndrehzahl berechnet werden.
Der Anfahrvorgang soll für beliebige vorgegebene Windgeschwindigkeiten, Betriebsdrehzahlen und Pitchwinkel zu Beginn des Anfahrvorgangs funktionieren.

Leider stimmt das Ergebnis nicht. Kann mir einer sagen, ob ich auf dem richtigen Weg bin?

Ich bedanke mich für jede Hilfe.
