Description
Großwindkraftwerk mit gleichachsig hintereinanderliegenden Hauptwindrädern und diesen vorgeschaltetem Hilfswindrad Die Erfindung bezieht sich auf Großwindkraftwerke, bei denen die elektrischen Stromerzeuger unmittelbar an den Windrädern angeordnet und zu diesem Zweck jeweils zwei gegenläufige, ,in geringem Abstande hintereinanderliegende Windräder auf einer Achse gelagert sind, von denen das. eine das induzierende und,das andere das induzierte Polsystem des Stromerzeugers trägt.Large wind power plant with main wind turbines lying one behind the other on the same axis and this upstream auxiliary wind turbine The invention relates to large wind power plants, in which the electric power generator is arranged directly on the wind turbines and for this purpose two opposing directions, one behind the other at a short distance Wind turbines are mounted on an axle, one of which is the inducing and, the others carry the induced pole system of the power generator.
Nach der Erfindung wird den gleichachsig hintereinanderliegenclen - Hauptwindrädern eines solchen Windkraftwerkes ebenfalls gleichachsig ein Hilfswindrad vorgelagert, 'dessen Durchmesser etwa ein Drittel so groß ist wie der Durchmesser des. vorderen luvseitigen Hauptwindrades und das die Erregermaschine des - Hauptstromerzeugers antreibt.According to the invention, the coaxially lie one behind the other - Main wind turbines of such a wind power plant also coaxially an auxiliary wind turbine upstream, 'whose diameter is about a third as large as the diameter of the front wind turbine and the exciter of the main power generator drives.
Es ist zwar schon vorgeschlagen worden, den von einem Hilfswindrad erzeugten Strom zu benutzen, um auf den Hauptstromerzeuger Einfluß zu nehmen, einmal zur Beeinflussung der Feldwicklung des Hauptstromerzeugers, zum anderen zur Regelung eines im Ankerstromkreis des Hauptstromerzeugers liegenden Widerstandes. Hierbei hat man auch schon das Hilfswindrad gleichachsig zum Hauptwindrad angeordnet und diesem vorgelagert.It has already been suggested that an auxiliary wind turbine be used to use generated electricity to influence the main electricity generator, once to influence the field winding of the main power generator, on the other hand for regulation a resistor in the armature circuit of the main power generator. Here the auxiliary windmill has already been arranged coaxially with the main windmill and upstream of this.
Im Gegensatz zu den für Regelzwecke vorgesehenen kleinen Windrädern der bekannten Windkraftmaschinenwird nach der Erfindung den Hauptwindrädern ein leistungsfähiges Hilfswindrad vorgelagert, und zwar wird diesem Hilfswindrad etwa ein Drittel der Größe gegeben, welche das vordere Hauptwindrad besitzt. Hiermit sind eine Reihe von überraschenden Vorteilen verbunden. Es hat sich nämlich gezeigt, daß das von einem Drittel .des Radius umgrenzte Druckfeld in der Mitte einer aus zwei gleichachsig hintereinder liegenden-, gegenläufigen Windrädern bestehenden Wimdkraftmaschine fast wirkungslos bleibt, weil der Durchfluß in der Nähe der Nabe gestört ist und daher innerhalb dieser Zone eine abbremsende Wirkung auftritt. Durch ein vorgelagertes, leistunggebendes Hilfswindrad werden dann, wenn dies Hilfswindrad gerade den genannten Strömungsquerschnitt erfaßt, die Druck- und Wirbelverluste im Mittelfeld der Hauptwindräder vermindert. Legt man nun das Hilfswindrad weit genug, beispielsweise um eine Entfernung, die seinem Radius entspricht, vor das vordere Hauptwindrad, so wird es von der im Mittelfeld der Hauptwindräder auftretenden Strömungsstörung nicht mehr merklich beeinflußt und es vermag dem vorgelagerten Strömungsfeld dann etwa ein Zehntel derjenigen Leistung zu entnehmen, welche die Hauptwindräder liefern. Seine Leistung reicht also aus, um die Erregung für den von den Hauptwindrädern angetriebenen Stromerzeuger nicht nur zu steuern, sondern unmittelbar zu decken. Der Kernpunkt der Erfindung liegt also in der Erkenntnis, daß sich die zur Erregung des Hauptstromerzeugers erforderliche elektrische Leistung mit den angege'uenen Mitteln in windabhängiger Form unmittelbar gewinnen läßt, ohne daß Energieverluste im Hauptstromerzeuger hierdurch zu verzeichnen sind.In contrast to the small wind turbines intended for control purposes of the known wind power machines becomes, according to the invention, the main wind turbines powerful auxiliary wind turbine upstream, namely this auxiliary wind turbine is about given a third of the size of the front main wind turbine. Herewith are associated with a number of surprising advantages. It has been shown that that the pressure field delimited by a third of the radius in the middle of one two coaxially rearward lying, opposing wind turbines existing Wimdkraftmaschine remains almost ineffective because the flow is close to the hub is disturbed and therefore a decelerating effect occurs within this zone. By an upstream, power-providing auxiliary wind turbine will be used if this is an auxiliary wind turbine just recorded the flow cross-section mentioned, the pressure and vortex losses decreased in the middle of the main wind turbines. If you now put the auxiliary wind turbine far enough, for example, by a distance equal to its radius before the front main wind turbine, it will be different from the one occurring in the middle field of the main wind turbines Flow disturbance no longer noticeably influenced and it is capable of the upstream Flow field can then be taken from about a tenth of that power, which the Supply main wind turbines. So its power is sufficient to generate arousal for the Not only to control power generators driven by the main wind turbines, but also to cover immediately. The essence of the invention lies in the knowledge that the electrical power required to excite the main power generator with the indicated means in wind-dependent form can win directly, without that energy losses in the main electricity generator are recorded as a result.
Die Abbildung .gibt schematisch ein Ausführungsbeispiel .für eine erfindungsgemäße Anordnung im Querschnitt wieder. Die Hauptwindräder i und 2 tragen die Polringe i" und 2Q, welche gemeinsam den von ihnen angetriebenen Stromerzeuger bilden. Als Achse der beiden Windräder dienen zwei Kreisschienenpaare 3 und 4, die mittels entsprechender Stützkonstruktionen von den Auslegern 5 und 6 getragen werden. Konzentrisch zu den Kreisschienenpaaren 3, 4 ist die Welle 7 in den Auslegern 5, 6 gelagert, welche das luvseitig den Hauptwindrädern i, :2 vorgelagerte Hilfswindrad 8 trägt. Der Durchmesser des Hilfswindrades 8 ist etwa ein Drittel so groß wie der Durchmesser des vorn liegenden Hauptwindrades i. Um den Strömungswiderstand von Achse und Nabe zu vermindern, können diese Teile mit einer stromlinienförmigen Ummantelung ausgerüstet sein. Um weiterhin die Wirbelbildung innerhalb des hinter dem Hilfswindrad 8 liegenden Strömungsquerschnittes her-.abzusetzen, können die Flügel der Hauptwindräder 1, 2 innerhalb der gestrichelt angedeuteten Zone a auf die zulässig kleinste Breite gebracht und so gegen den Wind angestellt werden, daß sie kein merkliches Antriebsmoment durch die Windströmung erhalten.The figure shows schematically an exemplary embodiment for a Arrangement according to the invention in cross section again. The main wind turbines i and 2 carry the pole rings i "and 2Q, which together are the power generators they drive form. Two pairs of circular rails 3 and 4 serve as the axis of the two wind turbines are supported by the arms 5 and 6 by means of appropriate support structures. The shaft 7 in the cantilevers 5 is concentric to the circular rail pairs 3, 4, 6 stored, which the windward side the main wind turbines i,: 2 upstream auxiliary wind turbine 8 carries. The diameter of the auxiliary pulley 8 is about a third as large as that Diameter of the main wind turbine in front i. To reduce the flow resistance of To reduce the axle and hub, these parts can be given a streamlined casing be equipped. To continue the vortex formation inside the rear of the auxiliary wind turbine 8 lower flow cross-section, the blades of the main wind turbines can 1, 2 within the zone a indicated by dashed lines to the smallest permissible width brought and hired against the wind so that they have no noticeable drive torque obtained by the wind flow.
