Abstract
Description
Die Erfindung betrifft eine Windenergieanlage mit einem mit Abspannungen versehenen Mast.The invention relates to a wind turbine with a mast with bracing.
Die Nabenhähe des Rotors einer Windenergieanlage hat auf den Ertrag und damit auf die Wirtschaftlichkeit der Windenergieanlage einen wichtigen Einfluß. Dabei gilt, daß der Ertrag umso besser ist, je größer die Nabenhähe des Rotors ist. Die Nabenhöhe einer Windenergieanlage ist durch die Höhe des Turms bestimmt, auf dem die Gondel, in dem der Rotor gelagert ist, gehalten ist.The hub close-up of the rotor of a wind turbine has on the yield and thus on the profitability of the wind turbine an important influence. It applies that the The bigger the yield, the better the yield Nabenhähe of the rotor. The hub height a wind turbine is determined by the height of the tower which the nacelle in which the rotor is mounted is held.
In Windenergieanlagen werden für die Aufnahme der Gondel sowohl freitragende Türme als auch abgespannte Masten eingesetzt. Freitragende Türme besitzen eine hohe Nick- und Torsionssteifigkeit, erfordern hierfür allerdings einen hohen Materialeinsatz, wenn sie biegesteif gebaut werden sollen, Abgespannte Masten sind besonders bei kleineren Anlagen sehr verbreitet, weil sie leichter als freitragende Türme sind und sich gut für einen Aufbau der Windenergieanlage mit Jütbaum und Winde eignen. Bei einem derartigen Aufbau der Windenergieanlage lassen sich außerdem Kosten beim Transport und bei der Montage reduzieren. Wegen der Schwingneigung van abgespannten Masten ist die Höhe von Windenergieanlagen mit derartigen Masten jedoch begrenzt.In wind turbines are used for inclusion the gondola both cantilevered towers as well as guyed masts. Own unsupported towers high pitch and torsional rigidity, however, are required for this a high amount of material, if they are to be built rigid, guyed Masts are particularly common in smaller systems because they are lighter than cantilevered towers are and are good for a structure of the wind turbine with Jütbaum and winch are suitable. at Such a construction of the wind turbine can also be costly reduce during transport and assembly. Because of the tendency to vibrate of guyed masts is the height of wind turbines with however, such masts are limited.
Der Erfindung liegt die Aufgabe zugrunde, das Betriebsver halten einer Windenergieanlage mit einem mit Abspannungen versehenen Mast zu verbessern.The invention has for its object that Betriebsver behave a wind turbine with a guy provided mast to improve.
Diese Aufgabe wird durch die im Anspruch 1 gekennzeichneten Merkmale gelöst. Durch die Dämpfung der Schwingungen des Masts wird die Anregung von Schwingungen des Rotors aufgrund von Schwingungen des Masts vermindert. Ebenso wird die Anregung von Schwingungen des Masts aufgrund von Schwingungen des Rotors vermindert. Die Dämpfung der Schwingungen des Masts verringert die Betriebslasten der Windenergieanlage und damit auch eine Gefährdung von Bestandteilen des Antriebsstrangs, wie z. B. Lagern und Getriebe. Die Verbesserung des Betriebsverhaltens erlaubt es, höhere maximale Drehzahlen des Rotors zuzulassen.This task is claimed by the 1 marked features solved. By damping the vibrations of the mast is the excitation of vibrations of the Rotors decreased due to mast vibrations. Likewise, the Excitation of mast vibrations due to vibrations of the Rotors decreased. The damping the vibrations of the mast reduce the operating loads of the wind turbine and therefore also a hazard components of the drive train, such as. B. bearings and gears. The improvement in operating behavior allows higher maximum Allow speeds of the rotor.
Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet. Sie beziehen sich insbesondere auf die Ausbildung der Dämpfungsvorrichtung und auf ihre Anordnung bezüglich der Abspannung.Advantageous further developments of Invention are in the subclaims characterized. They relate in particular to training the damping device and their order regarding the guy.
