Abstract
Es wird mit dieser Patentanmeldung die Erteilung eines Patents auf eine neuartige Windkraftanlage (skalierbarer, vollgeregelter, luftgetriebener Energietransformer = SVL-Energietransformer) beantragt.Die Basis dieser Windkraftanlage beruht auf dem Grundprinzip einer, zwei oder mehreren angetriebenen geregelten Rotoren, die über geeignete Verbindungselemente auf einer zentralen Achse (Hauptachse) montiert sind. Sie nutzen den Magnus-Effekt als Rotations-/Antriebskraft für die Hauptachse aus und erzeugen so ein konstantes Drehmoment. Dieses Drehmoment wird mit Hilfe einer Verbindungswelle (Hauptachsenstrang) auf einen Generator übertragen.Die Rotoren sind mit einem speziellen zylinderförmigen Mantel (Bernoulli-Diffusor) umgeben, dessen Ende, entsprechend der Windgeschwindigkeit, mit einer adaptiven Steuerung versehen ist.Die Rotoren haben in ihrer Innenseite Endscheiben und sind am anderen Ende entsprechend den Abmessungen des Bernoulli-Diffusors als Kalotte ausgebildet.Die Anwendung von adaptiven Oberflächenstrukturen verbessert im erheblichen Maße die Aerodynamik und damit die Leistung der Windkraftanlage.Das embedded, adaptive Reglersystem gewährleistet eine robuste, stetige Leistungsabgabe.Die abgegebene elektrische Leistung des Generators hängt primär von den geometrischen Abmessungen der Windkraftanlage und den vorherrschenden Windverhältnissen ab.This patent application applies for a patent for a new type of wind power plant (scalable, fully regulated, air-driven energy transformer = SVL energy transformer) central axis (main axis) are mounted. They use the Magnus effect as a rotational / driving force for the main axis and thus generate a constant torque. This torque is transmitted to a generator with the help of a connecting shaft (main axle line). The rotors are surrounded by a special cylindrical casing (Bernoulli diffuser), the end of which is provided with an adaptive control according to the wind speed. The rotors have inside End plates and at the other end are designed as a dome according to the dimensions of the Bernoulli diffuser. The use of adaptive surface structures improves the aerodynamics and thus the performance of the wind turbine considerably. The embedded, adaptive control system ensures a robust, constant power output. The electrical output The output of the generator depends primarily on the geometric dimensions of the wind turbine and the prevailing wind conditions.
Description
Der SVL-Energietransformer (SVL=skalierbar, vollgeregelt, luftgetrieben) (Bild 1) ist als klein- bis mittelgroße Anlage zur Erzeugung von Elektrizität konzipiert.
Er besteht aus einer, zwei oder mehreren angetriebenen geregelten Rotoren, die über geeignete Verbindungselemente auf einer zentralen Achse (Hauptachse) montiert sind. Sie nutzen den Magnus-Effekt als Rotations-/Antriebskraft für die zentrale Achse aus, über die ein Generator angetrieben wird.The SVL energy transformer (SVL = scalable, fully regulated, air-driven) (Fig. 1) is designed as a small to medium-sized system for generating electricity.
It consists of one, two or more driven, regulated rotors, which are mounted on a central axis (main axis) using suitable connecting elements. They use the Magnus effect as a rotational / driving force for the central axis, which drives a generator.
Dieses Konzept kann im in Abhängigkeit seines Maßstabs, sowohl zur Erzeugung von Windenenergie in herkömmlichen Sinn (vgl. Windkraftanlage) als auch zur Aufladung von Speichern in elektromobilen Anwendungen eingesetzt werden.Depending on its scale, this concept can be used both to generate wind energy in the conventional sense (cf. wind power plant) and to charge storage devices in electromobile applications.
In letzterer Funktion führt dies zu längeren Einsatzzeiten/Reichweiten oder Gewichtsreduzierungen der Energie-Speicher-Systeme.In the latter function, this leads to longer operating times / ranges or weight reductions in the energy storage systems.
Die Windkraftanlage kann durch verschiedene technologische Maßnahmen (s. unten) in seiner Leistung gesteigert bzw. an den individuellen Bedarf angepasst werden.The performance of the wind power plant can be increased or adapted to individual needs through various technological measures (see below).
Zur Leistungsverbesserung sind die Rotoren mit einem Bernoulli-Diffusor umgeben (Bild 1 bis Bild 8). Der Bernoulli-Diffusor besteht aus einem zylinderförmigen Rohr dessen Ende mit einer Verstelldüse versehen ist. Deren Öffnungswinkel wird bestimmt durch die Windgeschwindigkeit, die Rotorzahl und die Rotorgeschwindigkeit.To improve performance, the rotors are surrounded by a Bernoulli diffuser (Fig. 1 to Fig. 8). The Bernoulli diffuser consists of a cylindrical tube, the end of which is provided with an adjustable nozzle. Their opening angle is determined by the wind speed, the number of rotors and the rotor speed.
Durch die zusätzliche Drehung der Rotoren um die Hauptachse ändert sich die Druckverteilung über die Längsachse der Rotoren. D. h. es ist daher eine von einem Zylinder abweichende Form der Druckverteilung. Sie muss berücksichtigen, dass die Position der Staupunkte der Strömung, - bezogen auf die Längsachse der Rotoren, einen konstanten Wert haben (Bild 2). Die Form muss daher rechnerisch aus den Auslegungsparametern ermittelt werden.The additional rotation of the rotors around the main axis changes the pressure distribution over the longitudinal axis of the rotors. I. E. it is therefore a form of pressure distribution that differs from that of a cylinder. It must take into account that the position of the stagnation points of the flow - in relation to the longitudinal axis of the rotors, have a constant value (Fig. 2). The shape must therefore be calculated from the design parameters.
Die äußeren Enden der Rotoren sind entsprechend des Durchmessers des Bernoulli-Diffusor als Kalotte ausgebildet. Die inneren Seiten der Rotoren sind mit Endscheiben versehen, deren Durchmesser für die jeweilige Anwendung optimiert ist.The outer ends of the rotors are designed as a dome, corresponding to the diameter of the Bernoulli diffuser. The inner sides of the rotors are provided with end plates, the diameter of which is optimized for the respective application.
Die Oberflächen der Rotoren sind mit einer adaptiven Oberflächenstruktur (z. B. Dimpels (Golfball)), Grenzschichtzäune, Riffelung, Rauheit) versehen. Die jeweilige Auswahl/Kombination dieser Strukturen bestimmt das Verhalten von laminarer und nichtlaminarer Grenzschicht und damit auch die Leistung des Gesamtsystems. Die jeweilige Auswahl/Anwendung hängt von der Systemauslegung dem Betriebsmodus und dem Einsatzort ab.The surfaces of the rotors are provided with an adaptive surface structure (e.g. dimpels (golf ball), boundary layer fences, corrugation, roughness). The respective selection / combination of these structures determines the behavior of the laminar and non-laminar boundary layer and thus also the performance of the overall system. The respective selection / application depends on the system design, the operating mode and the place of use.
Messungen mit vereinfachten Modellanordnungen und mit adaptiven Strukturen lassen eine erhebliche Leistungssteigerung des Gesamtsystems erwarten.Measurements with simplified model arrangements and with adaptive structures lead to the expectation of a considerable increase in the performance of the overall system.
Die Auslegung des Reglersystems wird bestimmt durch die anvisierte Anwendung bzgl. des Betriebseinsatzes und den Umweltbedingungen. Diese bestimmen wiederum die physikalischen Auslegungsparameter der Rotoren, des Bernoulli-Diffusors und des Reglersystems (Anströmgeschwindigkeit, Drehzahl der Rotoren und die der Hauptachse).The design of the control system is determined by the intended application in terms of operational use and the environmental conditions. These in turn determine the physical design parameters of the rotors, the Bernoulli diffuser and the control system (flow velocity, speed of the rotors and that of the main axis).

- ■ Rechner
- ■ Sensoren (Wind, Drehzahlen (Hauptachse, Rotoren) u.a.)
