Abstract
Description
Es ist bekannt, daß Horizontalachsenwindkraftanlagen mechanisch geregelt wer den, indem ein Fliehkraftregler die Rotorblätter bei Übersteigen der Solldrehzahl mit ansteigender Drehzahl verstellt um den Anströmwinkel der Blätter zu ver ringern. Bei Drehzahlen unterhalb der Solldrehzahl bleiben die Blätter jedoch in Solldrehzahl-Position.It is known that horizontal axis wind turbines are mechanically controlled the by a centrifugal governor the rotor blades when the target speed is exceeded adjusted with increasing speed to adjust the flow angle of the blades wrestle. At speeds below the target speed, however, the blades remain in Target speed position.
Bei einigen Anlagen wird auch im unteren Drehzahlbereich (bei geringen Windge schwindigkeiten), insbesondere bei Stillstand des Rotors, der Blattwinkel verrin gert, um ein höheres Drehmoment zu erhalten, ohne das der Rotor bei niedrigen Windgeschwindigkeiten nicht anlaufen würde. Diese Anlagen sind jedoch elektro nisch geregelt.In some systems, even in the lower speed range (with low wind speeds), especially when the rotor is at a standstill, reduce the blade angle to get a higher torque without the rotor at low Wind speeds would not start. However, these systems are electrical nically regulated.
Eine elektronische Regelung ist meistens kompliziert, dadurch empfindlich und insbesondere bei kleinen Anlagen oft verhältnismäßig zu teuer. Gerade bei Wind kraftanlagen, denen mechanische Arbeit abgefordert wird, z. B. bei Windpumpen, ist ein hohes Anlaufdrehmoment sehr wichtig, da ohne die zuletzt beschriebene Regelung nur durch eine Überdimensionierung der Rotorfläche erreicht werden kann.Electronic control is usually complicated, therefore sensitive and often relatively expensive, especially for small systems. Especially in the wind Power plants that require mechanical work, e.g. B. in wind pumps, a high starting torque is very important because without the last one described Regulation can only be achieved by oversizing the rotor area can.
Der Erfindung liegt das Problem zugrunde, eine einfache, robuste und billige mechanische Regelung zu erhalten, die sowohl im Überdrehzahlbereich den Blattwinkel verringert, um ein Überdrehen zu verhindern, als auch im Unter drehzahlbereich, um das Anlaufdrehmoment zu vergrößern.The invention is based on the problem of being simple, robust and cheap to obtain mechanical control, both in the overspeed range Blade angle reduced to prevent over-turning, as well as in the under speed range to increase the starting torque.
Die mit der Erfindung erzielten Vorteile liegen darin, daß die Rotorfläche knapp dimensioniert und insgesamt die Anlage preisgünstig hergestellt werden kann und dennoch sehr effektiv arbeitet. Daneben ist die Regelung gegenüber einer elektronischen robuster und somit betriebssicherer, was die Wartung der gesam ten Anlage vereinfacht und einen Einsatz an abgelegenen Orten, z. B. als Weide- oder Fischteichpumpe, oder auch in Entwicklungsländern interessant macht.The advantages achieved with the invention are that the rotor area is scarce dimensioned and overall the system can be manufactured inexpensively and still works very effectively. In addition, the regulation is against one electronic robust and thus more reliable, which the maintenance of the whole th system simplified and use in remote locations, such. B. as a pasture or fish pond pump, or also interesting in developing countries.
Die Erfindung wird nachfolgend anhand der Figuren genauer beschrieben.The invention is described in more detail below with reference to the figures.
Es zeigt Fig. 1 in schematischer Darstellung eine Seitenansicht der Regelmecha nik aus Anspruch 1). Darin sind zu sehen: Der Fliehkraftregler, bestehend aus einem beweglichen Gestänge (1), dem Fliehgewicht (2), der Gegenfeder (3) und der Reglerstange (4).It shows Fig. 1 in a schematic representation a side view of Regelmecha technology from claim 1). The following can be seen: The centrifugal force regulator, consisting of a movable linkage ( 1 ), the centrifugal weight ( 2 ), the counter spring ( 3 ) and the regulator rod ( 4 ).
Dieser bewegt bei zunehmender Drehzahl durch Vorschieben der Reglerstange (4) über das Zahnrad-Kurbel-Getriebe, bestehend aus dem Anlenkpleuel (5), dem großen Zahnrad (6), dem kleinen Zahnrad (7) und dem Steuerpleuel (8), das An lenkgestänge, bestehend aus einem Steuerkopf (9) und je Rotorblatt einer Pleuel stange (10).This moves with increasing speed by advancing the control rod ( 4 ) over the gear crank mechanism, consisting of the articulated connecting rod ( 5 ), the large gear ( 6 ), the small gear ( 7 ) and the control connecting rod ( 8 ) Steering linkage, consisting of a control head ( 9 ) and a connecting rod ( 10 ) per rotor blade.
Das Zahnrad-Kurbel-Getriebe formt die lineare Bewegung der Reglerstange (4) in eine alineare um, die im Steuerkopf (9) wirksam wird. Die Regelmechanik befin det sich in der Solldrehzahl-Stellung, wenn die Kurbelstange des kleinen Zahn rades (7) mit dem Steuerpleuel (8) auf einer Achse liegt, bzw. wenn der Steuer kopf (9) am weitesten herausgeschoben ist.The gear-crank transmission transforms the linear movement of the control rod ( 4 ) into an alinear one, which takes effect in the control head ( 9 ). The control mechanism is in the target speed position when the crank rod of the small gear wheel ( 7 ) with the control rod ( 8 ) is on one axis, or when the control head ( 9 ) is pushed out the most.
Das Anlenkgestänge verstellt den Anstellwinkel des Rotorblattes durch verdre hen der drehbar gelagerten Blatthalterung (11).The linkage adjusts the angle of attack of the rotor blade by turning the rotatably mounted blade holder ( 11 ).
In Fig. 2 ist ebenfalls in schematischer Darstellung die Mechanik nach Anspruch 2 gezeigt. Darin passiert die Anlenkung des Steuerkopfes durch eine Schub stangenvorrichtung, bestehend aus der Reglerstange (4), den Schubstangen (12) und (13), dem Umlenkhebel (14) und dem Schubteller (15), der mittels der Zug feder (16) gegen die Schubstange (12), bzw. (13) gehalten wird.In Fig. 2, the mechanism according to claim 2 is also shown in a schematic representation. In it happens the articulation of the control head by a push rod device, consisting of the control rod ( 4 ), the push rods ( 12 ) and ( 13 ), the bellcrank ( 14 ) and the push plate ( 15 ), by means of the tension spring ( 16 ) against the push rod ( 12 ) or ( 13 ) is held.
Die lineare Bewegung der Reglerstange (4) wird hier durch den Umlenkhebel in eine alineare umgeformt, die im Steuerkopf (9) wirksam wird. Die Regelmechanik befindet sich in Solldrehzahl-Stellung, wenn der Umlenkhebel (14) senkrecht zur Reglerstange (4) steht, bzw. wenn die Schubstangen (12) und (13) auf gleicher Höhe stehen und der Steuerkopf (9) am wenigsten herausgeschoben ist.The linear movement of the regulator rod ( 4 ) is transformed here by the deflection lever into an alinear, which is effective in the control head ( 9 ). The control mechanism is in the target speed position when the bell crank ( 14 ) is perpendicular to the control rod ( 4 ), or when the push rods ( 12 ) and ( 13 ) are at the same height and the control head ( 9 ) is least pushed out.
Fig. 3 zeigt die herkömmliche Variante des Fliehkraftreglers, bei dem die An steuerung direkt, ohne Umlenkmechanik erfolgt. Fig. 3 shows the conventional variant of the centrifugal governor, in which the control is carried out directly, without a deflection mechanism.
In Fig. 4a bis 4c sind zur Veranschaulichung der Wirkungsweise in Form ei nes Graphen die jeweiligen Kennlinien der Regelungsvarianten gezeigt.In Fig. 4a to 4c of the operation in the form ei nes graph are shown the respective characteristics of the control options for illustration.
Dabei zeigt Fig. 4a den Anstellwinkel in Abhängigkeit von der Rotordrehzahl für die Mechanik aus Anspruch 1, Fig. 4b zeigt die gleiche Kennlinie für die Regelung aus Anspruch 2. Here, Fig. 4a shows the angle of attack as a function of the rotor speed for the mechanism of claim 1, Fig. 4b shows the same characteristic curve for the control of claim 2.
In Fig. 4c ist die Kennlinie für die herkömmliche Variante gezeigt.The characteristic curve for the conventional variant is shown in FIG. 4c.
