Abstract
Description
Die Erfindung betrifft eine Windkraftanlage gemäß den Oberbegriff des Anspruchs 1.The The invention relates to a wind turbine according to Preamble of claim 1.
Alle
Windkraftanlagen mit horizontaler Rotationsachse des Windrades müssen
der Windrichtung nachgeführt werden. Dazu ist die Gondel
mit dem Windrad und mit dem Elektrogenerator horizontal um eine
vertikale Gierachse drehbar auf dem Turm angebracht. Windkraftanlagen,
deren Windräder auf der Leeseite des Turmes angeordnet
sind, brauchen den komplizierten Windnachführungsmechanismus mit
dem Windrichtungsgeber und mit den Stellmotoren nicht. Der Wind
wirkt auf das Windrad ein und dreht die Gondel automatisch gegen
den Wind und sorgt für eine sogenannte passive Windnachführung (z.
B.
Aber
bei solchem Verfahren der Windnachführung entstehen sogenannte
Nick- und Gierschwingungen der Gondel mit dem Windrad und mit dem
Elektrogenerator, deren Amplituden und Frequenzen die unzulässigen
Größen erreichen können. Um solche Schwingungen
zu dämpfen, benutzt man verschiedene Vorrichtungen und
Verfahren (z. B.
Der Anmeldung liegt offensichtlich die Aufgabe zugrunde, die Windkraftanlage zu schaffen, die einfach in seinem Aufbau ist, zuverlässig über lange Betriebszeiten arbeitet und deren Stromerzeugung gegenüber den bisher bekannten Windkraftanlagen verbessert und nicht aufwendig ist.Of the Registration is obviously the task underlying the wind turbine to create that is simple in its construction, reliable over long operating times and their power generation compared the previously known wind turbines improved and not consuming is.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Windkraftanlage die Windfahne oder das zusätzliche Windrad, die auf der Luvseite des Turmes angeordnet sind, aufweist.These The object is achieved according to the invention that the wind turbine the wind vane or the additional Pinwheel, which are arranged on the windward side of the tower, has.
Die Ausführungsbeispiele der Erfindung sind in den Zeichnungen dargestellt, hierbei sind nur die Oberteile der Windkraftanlagen zu sehen. Es zeigenThe Embodiments of the invention are in the drawings shown here are only the tops of the wind turbines to see. Show it
