Abstract

The wind turbine for electricity generation has a vertical rotor (2) supported by a tubular mast (7), with stabilisation at the centre via a gyro (3). The rotor (2) is used for direct drive of a number of ring generators (8) with a stator supported by a base, supported resiliently by the reinforced steel foundation (11), The rotor of the ring generator (8) is supported by a roller bearing. Pref. a series of ring generators (8) are switched in circuit to match the different wind velocities. ADVANTAGE- High power output compared to cost.

Description

Die Erfindung hat eine Windturbine (Fig. I) mit den Merkmalen nach An­ spruch 1 zum Gegenstand. Weiterbildungen dieses Gegenstandes ergeben sich aus den Unteransprüchen.The invention has a wind turbine ( Fig. I) with the features of claim 1 to the subject. Further developments of this subject result from the subclaims.

Entscheidend für die Weiterentwicklung der Windenergie ist allein die wirtschaftliche Durchsetzbarkeit und die Erreichung eines Preis/Leistungs­ minimums unter DM 2.000,-/KW, aber dieser Wert liegt im Augenblick über DM 3.000,-.That alone is decisive for the further development of wind energy economic feasibility and the achievement of a price / performance minimums below DM 2,000 / KW, but this value is currently above DM 3,000.

Der weiterentwickelte Ringgenerator (8) brachte dem Vertikalrotor den Durch­ bruch. Erst heute ist es möglich, im Zusammenhang mit der Stabilisierung durch einen Kreisel (3) den Rotor als Großwindanlage zu realisieren. Der direkt vom Rotor (2) angetriebene Ringgenerator (8) erspart uns das bisher unverzichtbare Getriebe, da es einen hohen Reibungsverlust brachte und sehr aufwendig war, kann man künftig durch zwei oder mehrere kleinere Ringgeneratoren, die hintereinander geschaltet, den gleichen Zweck er­ reichen, so daß der gesamte Leistungsbereich abgeregelt werden kann. Durch die Anordnung der Ringgeneratoren, die nun übereinanderliegen, können jetzt wahlweise in Reihenschaltung hin und zurück geschaltet werden und bringen einen Wirkungsgrad, der nicht unwesentlich zur Kostensenkung bei­ trägt. Dadurch können nun auch größere Leistungsreserven freigemacht werden, die bisher wegen Sturmgefahren stillgelegt waren, da die Generatoren so hohe Leistungsbereiche nicht abdecken konnten.The further developed ring generator ( 8 ) brought the breakthrough to the vertical rotor. Only today is it possible to implement the rotor as a large wind turbine in connection with the stabilization by means of a gyro ( 3 ). The ring generator ( 8 ), which is driven directly by the rotor ( 2 ), saves us the previously indispensable gearbox, since it caused a high level of friction loss and was very expensive. In the future, two or more smaller ring generators, which can be connected in series, can achieve the same purpose. so that the entire performance range can be limited. Due to the arrangement of the ring generators, which are now one above the other, you can now switch back and forth in series and bring an efficiency that contributes significantly to the reduction in costs. As a result, larger power reserves can now be freed up that were previously closed due to storm hazards, since the generators could not cover such high power ranges.

Die Erfindung sieht die Lösung der Problematik im Einbau von mehreren kleineren Ringgeneratoren vor, die den gleichen Preis kosten, aber wesentlich effektiver im Einsatz sind.The invention sees the solution to the problem in the installation of several smaller ring generators that cost the same price, but significantly are more effective in use.

Da die stationären Generatoren (8), der auf dem Rohrmast federnd ange­ ordneten Lagerbasis (7I) zugeordnet sind, ist eine Laufberuhigung gewähr­ leistet und wird durch den Kreisel (3) noch erhöht. Durch die Verbesserung des Schwingungsverhaltens können jetzt Baugrößen in extrem großen Dimen­ sionen ausgelegt werden, die noch technisch realisierbar das Preis/Leistungsgefüge entscheidend beeinflußen können.Since the stationary generators ( 8 ) are assigned to the bearing base ( 7 I) which is resiliently arranged on the tubular mast, a smooth running is guaranteed and is increased by the gyroscope ( 3 ). By improving the vibration behavior, sizes can now be designed in extremely large dimensions, which can still have a decisive technical impact on the price / performance structure.
