Die Erfindung bezieht sich auf eine Windkraftanlage mit Windturbine mit Diffusor.The invention relates to a wind power plant with a wind turbine with diffuser.

Schon vor mehr als 20 Jahren wurde bei Windkanalversuchen festgestellt, daß die Energieausbeute eines Windrotors mit Diffusor etwa sechsmal so hoch ist, wie die eines herkömmlichen Windrades. Auch dann, wenn man eine vereinfachte Form des Diffusors wählt und den Leistungsbeiwert auf die maximale Querschnittsfläche des Diffusors bezieht, ist die Energieausbeute trotzdem viel höher als von einem konventionellen Windrad. Durch die Ummantelung bzw. den Diffusor entsteht hinter dem Windrad ein Unterdruck, der die Geschwindigkeit des Luftstroms über den Rotorblättern verdoppeln kann.More than 20 years ago, wind tunnel tests showed that the energy yield of a wind rotor with a diffuser is about six times higher than that of a conventional wind turbine. Even if a simplified form of diffuser is chosen and the power coefficient is related to the maximum cross-sectional area of the diffuser, the energy yield is still much higher than that of a conventional wind turbine. The casing or diffuser creates a negative pressure behind the wind turbine that can double the speed of the air flow over the rotor blades.

Die hohe Energieausbeute ist auch mit der Zirkulationstheorie erklärbar. Der Diffusor bewirkt eine zusätzliche Zirkulationsströmung, deren Geschwindigkeitskomponenten im Diffusor gleichsinnig mit der Windströmung gerichtet sind und diese verstärkt. Der Leistungsbeiwert des Rotors steigt auf Werte von 2,0 bis 2,5 bezogen auf die Rotorfläche.The high energy yield can also be explained by the circulation theory. The diffuser causes an additional circulation flow, the speed components of which in the diffuser are directed in the same direction as the wind flow and strengthen it. The power coefficient of the rotor increases to values of 2.0 to 2.5 based on the rotor area.

Aber trotz dieses großen energetischen Vorteils kam es nicht zur Verbreitung von Windturbinen mit Diffusor. Der Grund dafür liegt im aufwendigen Azimutlager, welches statt gleich unter der Windturbinen-Gondel unter dem Diffusor-Ring angeordnet sein muß, wodurch große Momente entstehen, welche das Azimutlager belasten. Ein weiteres Problem ist die Herstellung und Montage des Diffusor-Ringes vor Ort, weil ein Ring von hundert oder mehr Meter im Durchmesser mit keinem Verkehrsmittel über Land transportiert werden kann.But despite this great energy advantage, wind turbines with diffusers did not become widespread. The reason for this is the complex azimuth bearing, which has to be arranged under the diffuser ring instead of directly under the wind turbine nacelle, which creates large moments that strain the azimuth bearing. Another problem is the manufacture and assembly of the diffuser ring on site, because a ring with a diameter of one hundred or more meters cannot be transported over land using any means of transport.

Der Erfindung liegt die Aufgabe zugrunde, eine Windkraftanlage mit Windturbine mit Diffusor so auszubilden, daß eine rationale Herstellung und Montage, welche eine hohe Rentabilität der Anlage gewährleistet, ermöglicht wird.The invention is based on the object of designing a wind power plant with a wind turbine with diffuser in such a way that rational production and assembly, which ensures a high profitability of the plant, is possible.

Diese Aufgabe ist erfindungsgemäß dadurch gelöst, daß man Windturbinen mit Diffusor auf schwimmend und drehbar gelagerten Plattformen und Bauwerken anordnet. In diesem Fall kann auf Azimutlager, Giermotoren und schlanke elastische MastenThis object is achieved according to the invention by arranging wind turbines with diffusers on floating and rotatably mounted platforms and structures. In this case, azimuth bearings, yaw motors and slim elastic masts can be used.

verzichtet werden, weil sich die Plattform oder das Bauwerk* mit Windturbinen immer optimal zur Windrichtung positioniert. Dadurch, daß die Energieerzeugung durch Wind in Zukunft immer mehr im Offshorebereich stattfinden wird, läßt sich auch die Herstellung und Montage von kompletten Windkraftanlagen gemäß Erfindung optimal durchführen. Erfindungsgemäße Windkraftanlagen werden auf Werften komplett hergestellt und dann auf eigenem Kiel zum Einsatzort geschleppt und dort mit Hilfe eines mit dem Seebett verbundenen Pfahls drehbar gelagert.can be dispensed with because the platform or structure* with wind turbines is always optimally positioned in relation to the wind direction. As energy generation from wind will increasingly take place offshore in the future, the manufacture and assembly of complete wind turbines according to the invention can also be carried out optimally. Wind turbines according to the invention are completely manufactured in shipyards and then towed to the site of use on their own keel, where they are mounted so that they can rotate using a pile connected to the seabed.

Fig. 3: Durch abgesenkte Rümpfe 6 hat die halbschwimmende Plattform 5 hohe Wellenverträglichkeit und dreht sich um den Turm 7 immer optimal zur Windrichtung. Auf diese Weise kann auf aufwendige und anfällige Azimutlager und Giermotoren verzichtet werden. Die Windturbinen mit Diffusoren sind mit der Plattform fest verbunden.Fig. 3: Due to lowered hulls 6, the semi-floating platform 5 has a high wave tolerance and always rotates around the tower 7 optimally in relation to the wind direction. In this way, complex and vulnerable azimuth bearings and yaw motors are not required. The wind turbines with diffusers are firmly connected to the platform.

Fig. 4: Wegen der großen Trägheit wird die schwimmende Plattform mit Verdrängungsrümpfen 8 von Wellen kaum beeinflußt.Fig. 4: Due to the high inertia, the floating platform with displacement hulls 8 is hardly affected by waves.

Während windreicher winterlicher Tage und Nächte, wann der Energiebedarf besonders hoch ist, produziert die Windkraftanlage auf dem Dach soviel Strom, daß man den ganzen Energiebedarf decken kann. Neben dem energetischen Vorteil vermindert der Diffusor die Geräuschabstrahlung, wodurch die Verwendung von Windkraftanlagen wegen des niedrigen Geräuschpegels auch in besiedelten Gebieten möglich ist.Fig. 5: A conventional offshore wind turbine combined with a semi-floating platform with two wind turbines with diffusers. The increase in energy yield is far greater than the additional costs.
Fig. 7 shows a floating and rotatable house with a buoyant foundation 9, water basin 10, living module 11, photovoltaic system on the roof 12, solar wall 13 and wind turbine 1 with diffuser 2 on the roof. During windy winter days and nights, when energy demand is particularly high, the wind turbine on the roof produces so much electricity that the entire energy demand can be covered. In addition to the energy advantage, the diffuser reduces noise emissions, which means that wind turbines can also be used in populated areas due to the low noise level.
