Abstract
Description
Stand der TechnikState of the art
Die Erfindung geht aus von einer Vertikalachsenwindkraftanlage, nach der Gattung des Anspruchs 1, und von einem Verfahren zur Umwandlung von Windenergie mittels einer Vertikalachsenwindkraftanlage, nach der Gattung des Anspruchs 11.The Invention is based on a vertical axis wind turbine, after the genus of claim 1, and a method of conversion of wind energy by means of a vertical axis wind turbine, after the genus of claim 11.
Vertikalachsenwindkraftanlagen, bei denen die Drehachse des Rotors vertikal ist, gehören seit langem zum Stand der Technik. Am bekanntesten sind der Darrieus-Rotor, bei dem die Rotorblätter am oberen und unteren Ende der Achse befestigt sind und bogenförmig nach außen ragen, der H-Darrieus-Rotor, der dem Darrieus-Rotor im aerodynamischen Prinzip gleicht, aber gerade anstatt bogenförmige Blätter hat, und der Savonius-Rotor, der aus zwei an einer vertikalen Rotorachse angebrachten waagerechten Kreisscheiben besteht, zwischen denen zwei oder mehr halbkreisförmige gebogene Schaufeln bzw. Flügel senkrecht stehend angebracht sind, wobei die Schaufeln gegeneinander versetzt angeordnet, so dass ein Teil des Windes von den rechts und links gerade zur Strömung offenen Schaufelseiten umgeleitet wird und auf die Rückseite einer der dort konkaven Schaufeln einwirken kann.Vertical axis wind turbines, where the axis of rotation of the rotor is vertical, belong for a long time to the state of the art. Best known are the Darrieus rotor, where the rotor blades attached to the upper and lower end of the axle and bowed to Outside protrude, the H-Darrieus rotor, the Darrieus rotor in the aerodynamic Principle resembles, but has straight rather than arcuate leaves, and the savonius rotor, that of two horizontally mounted on a vertical rotor axis Circular disks consists, between which two or more semicircular curved blades or wings are mounted vertically, with the blades against each other arranged offset so that part of the wind from the right and left just to the flow open vane sides is redirected and on the back one of the concave blades can act there.
Nachteilig bei dem bekannten Darrieus-Rotor ist die schlechte Regelbarkeit und, dass der Darrieus-Rotor je nach Völligkeit des Rotors (= Blattzahl × Tiefe/Rotorradius), durch die Schnelllaufzahl des Rotors vorgegeben wird, im Allgemeinen nicht von alleine anläuft, so dass er eine Anlaufhilfe benötigt.adversely in the known Darrieus rotor is the poor controllability and that the Darrieus rotor, depending on the totality of the rotor (= number of blades × depth / rotor radius), is dictated by the speed of rotation of the rotor, in general does not start by itself, so he needs a start-up help.
Der größte Nachteil bei einem Savonius-Rotor liegt wohl in seinem Wirkungsgrad, der nur ca. 23% bis 28% erreicht, so dass Savonius-Rotoren vorwiegend als Anlaufhilfe für Darrieus-Rotoren sowie für Entlüftungszwecke bei Fabrikhallen, Autos und Schiffen verwendet werden. Zusätzlich sind wie bei allen Rotoren mit vertikaler Drehachse die Schaufeln beim Savonius-Rotor aufgrund der ständigen Wechsel der Anstellwinkel zur einwirkenden Strömung Lastwechseln ausgesetzt, welche im Zusammenspiel mit den Fliehkräften Schwingungen oder Materialbelastungen verursachen können.Of the biggest disadvantage in a Savonius rotor is probably in its efficiency, the only about 23% to 28%, so that Savonius rotors mainly as a starting aid for Darrieus rotors also for ventilation purposes used in factories, cars and ships. In addition are as with all rotors with a vertical axis of rotation the blades at Savonius rotor due to the constant Change of the angle of attack to the acting flow exposed to load changes, which in combination with the centrifugal forces vibrations or material loads can cause.
Ein allgemeiner Nachteil von Vertikalachsenwindkraftanlagen ist, dass sich in Abhängigkeit vom Rotortyp und der Art der Flügel die Flügel an einer Windkraftanlage mit vertikaler Rotordrehachse in einem etwa auf ein Viertel des Rotordrehkreises bezogenen Abschnitt im Arbeitsumlauf in einer zur Strömung ungünstigen und energetisch nicht nutzbaren Position befinden, so dass sie also auch nur den Teil der Strömung in nutzbare Energie umwandeln können, zu dem sie sich in einer dafür günstigen Stellung befinden. Ein weiterer Nachteil sind die Schwingungen und Belastungen der Flügelkonstruktion und deren Halterungen, die durch die zyklisch auftre tenden Lastwechsel verursacht werden, die wiederum durch die unterschiedliche Reaktion der Blätter oder Flügel auf die Strömung im Drehkreis entstehen. Hinzu kommt, dass die Flügel bzw. Blätter, je nachdem, auf welcher Seite ihres Drehkreises sie gerade durchlaufen (Luv – oder Leeseite des Rotors), auch die Seite wechseln, von der sie angeströmt werden. Der Effekt dieser Lastwechsel ähnelt einer durch ungleichmäßige Masseverteilung verursachten Unwucht und kann relativ starke Belastungen auf die Konstruktion ausüben.One The general disadvantage of vertical axis wind turbines is that in dependence of the rotor type and the type of wings the wings on a wind turbine with a vertical rotor axis of rotation in one approximately on a quarter of the rotor circuit related section in Work circulation in one to the flow unfavorable and energetically unusable position, so they so even just the part of the flow convert into usable energy, to which they are in one Great Position. Another disadvantage is the vibrations and Loads on the wing construction and their brackets, by the cyclically auftre border load changes caused, in turn, by the different reaction the leaves or wings up the flow arise in the turning circle. In addition, the wings or leaves, depending on which They are just going through their side of the turning circle (windward or leeward side of the rotor), also change the side from which they are flown. The effect of this load change is similar one due to uneven mass distribution caused imbalance and can be relatively heavy loads on the Exercise construction.
