Abstract
Description
Die Erfindung bezieht sich auf Windkraftmaschinen zur Gewinnung elektrischer Energie aus natürlicher Windenergie.The invention relates to wind turbines for Obtaining electrical energy from natural wind energy.
In mehreren Druckschriften wurde bereits der Gedanke geäußert, die windstauende bzw. windleitende Wirkung von Gebäudefronten und Dächern zur Verbesserung des Energiegewinnes von Windkraftanlagen zu nutzen (z. B. DE 38 44 376 A1, 31 24 892, 30 06 612, 30 49 624).The idea was already in several publications expressed the wind-blocking or wind-guiding effect of building fronts and roofs for improvement to use the energy gain from wind turbines (e.g. DE 38 44 376 A1, 31 24 892, 30 06 612, 30 49 624).
Alle vorgeschlagenen Varianten (Rotor senkrecht oder parallel zur Windrichtung, Nutzung verschiedener Windrichtungen, etc.) benötigen mehr oder weniger umfangreichen baulichen Aufwand, sie beeinträchtigen u. U. die Gebäudenutzung und sind vom ästhetischen und baurechtlichen Standpunkt her gesehen problematisch.All proposed variants (rotor vertical or parallel to the wind direction, use of different wind directions, etc.) need more or less extensive construction effort, they affect u. U. building use and are of aesthetic and problematic in terms of building law.
Das ungünstige Verhältnis von notwendigem Aufwand (Baukosten und technische Ausrüstung) und zu erwartendem Energiegewinn erschwert eine Realisierung derartiger Vorschläge überhaupt. Beispielsweise würde aber nur eine große Anzahl dieser relativ kleinen Windkraftanlagen einen nennenswerten Beitrag zu einer dezentralen elektrischen Energieversorgung aus regenerierbaren Quellen leisten.The unfavorable ratio of necessary effort (construction costs and technical equipment) and expected energy gain makes it difficult to implement such proposals at all. For example, only a large number of these would relatively small wind turbines a significant contribution to a decentralized electrical energy supply afford renewable sources.
In Außenwänden von Gebäuden sind zuweilen Ventilatoren eingebaut.There are sometimes fans in the outside walls of buildings built-in.
Speziell bei landwirtschaftlichen Wirtschaftsgebäuden in windexponierten Lagen findet sich häufig eine Ausrichtung der Längsseite des Grundrisses lotrecht zur Hauptwindrichtung (hierzulande z. B. meist Westen).Especially for agricultural farm buildings an orientation is often found in wind-exposed locations the long side of the floor plan perpendicular to the main wind direction (in this country e.g. mostly west).
Darüber hinaus sind derartige Wirtschaftsgebäude häufig mit sogenannten Heubelüftungsanlagen (vgl. DE 38 17 962 A1) ausgestattet, wobei sich der Heulüfter oder Ventilator in oder an der windzugewandten Außenseite befinden kann, ohne daß seine primäre Funktion (Heubelüftung o. ä.) beeinträchtigt wird.In addition, such farm buildings are common equipped with so-called hay ventilation systems (see. DE 38 17 962 A1), whereby the hay fan or fan in or on the outside can face the wind without its primary function (hay ventilation or similar) is impaired becomes.
Die Erfindung bezieht sich nun darauf, daß
der Ventilator (Rotor-Drehachse parallel zur Hauptwindrichtung)
mit der elektrischen Antriebsmaschine
als komplette Einheit zusätzlich zu ihrem eigentlichen
oder ursprünglichen Verwendungszweck auch zur
Gewinnung elektrischer Energie aus der natürlichen
Windenergie genutzt wird.
The invention now relates to the fact that
the fan (rotor axis of rotation parallel to the main wind direction) with the electric drive machine is used as a complete unit in addition to its actual or original purpose of use also for the production of electrical energy from natural wind energy.
Dazu muß sich der Ventilator in oder an der windzugewandten Außenseite bzw. Außenmauer des Gebäudes befinden. Abströmseitig ist dazu bei Generatorbetrieb alternativ zu den in den Heustock o. ä. führenden Windkanälen ein strömungsgünstiger Windkanal zur windabgewandten Gebäudeseite mittels handbedienter oder motorisch betriebener Klappe(n) zu eröffnen. Dieselbe(n) Klappe(n) kann (können) zur Sturmsicherung verwendet werden, indem mit ihr (ihnen) der Windkanal blockiert wird. Die windstauende bzw. windleitende Wirkung der Gebäudefront bewirkt eine Druckdifferenz zwischen windzugewandter und windabgewandter Gebäudefront und somit eine Vergrößerung des Energiegewinnes.To do this, the fan must be in or on the windward side Outside or outside wall of the building. On the downstream side, this is an alternative for generator operation to the wind tunnels leading into the haystack or similar a streamlined wind tunnel to the windward Building side by hand operated or motorized Open flap (s). The same flap (s) can be used for storm protection by with it the wind tunnel is blocked. The wind-blocking or wind-guiding effect of the building front causes a pressure difference between the windward and facing away from the building and thus an increase in energy gain.
Der Einbau von Ventilatoren bzw. Heulüftern ist bei den genannten Gebäuden ohnehin z. B. für die landwirtschaftliche Nutzung notwendig und deswegen in der Regel baurechtlich völlig unproblematisch und ästhetisch ohne nachteilige Wirkung, weil die betreffenden Außenseiten keine besondere Gliederung aufweisen, die eventuell gestört werden könnte.The installation of fans or hay fans is at the buildings mentioned z. B. for agricultural Use necessary and therefore usually Building law completely unproblematic and aesthetically without adverse effect because of the outsides concerned have no special structure that may be disturbed could be.
Bei Neuanlagen sind anteilig nur geringe zusätzliche Investitionen nötig; auch sind Nachrüstungen bestehender Anlagen finanziell und technisch unproblematisch, so daß die Realisierung einer Vielzahl derartiger doppeltgenutzter Anlagen möglich wird.In the case of new systems, there are only a few additional ones Investment needed; retrofits are also existing Investments financially and technically unproblematic, so that the realization of a variety of such double-use systems is possible.
Speziell bei landwirtschaftlichen Heubelüftungsanlagen ergibt sich die Situation, daß sie nur während einiger windarmer Sommerwochen zeitweise zur Heubelüftung genutzt werden. Den Rest des Jahres (windreichere Herbst-, Winter- und Frühjahrswochen) stehen sie voll für die Energiegewinnung zur Verfügung.Especially for agricultural hay ventilation systems the situation arises that they are only during some windless summer weeks used for hay ventilation will. The rest of the year (windy autumn, winter and spring weeks) they are fully dedicated to energy production to disposal.
Bei Axialventilatoren wird, wie bei Auftriebsläufern konventioneller Windkraftanlagen, die Beschaufelung nach der Tragflügeltheorie im Hinblick auf Leistungsbeiwert und Schnellaufzahl z. B. nach G. Schmitz so zu optimieren sein, daß im Zusammenwirken mit einer für Motorbetrieb (Ventilator) und Generatorbetrieb (Windkraftmaschine) ausgelegten elektrischen Maschine ein maximaler Energiegewinn erzielt wird (Schmitz G., Theorie und Entwurf von Windrädern optimaler Leistung, Wiss. Zeitschrift der Universität Rostock, 5. Jahrgang 1955/56). With axial fans, as with lift rotors conventional wind turbines, the blading after the Wing theory in terms of performance coefficient and Fast count z. B. to be optimized according to G. Schmitz that in conjunction with one for engine operation (Fan) and generator operation (wind turbine) designed electrical machine a maximum energy gain is achieved (Schmitz G., theory and design of wind turbines more optimal Performance, scientific University of Rostock magazine, 5th year 1955/56).
Wird, wie meist üblich, ein asynchroner Kurzschlußläufermotor (Innen- oder Außenläufermotor) als elektrischer Ventilatorantrieb verwendet, so kann mit einer polumschaltbaren Ständerdrehstromwicklung (Dahlander- oder PAM-Schaltung) dieser auch bei Wahl einer höheren Polzahl am Netz übersynchron als Generator gefahren werden, falls der Ventilator als Windkraftmaschine das entsprechende Drehmoment liefert.As is usually the case, becomes an asynchronous squirrel-cage motor (Internal or external rotor motor) as electrical Fan drive used, so can with a pole-changing stator three-phase winding (Dahlander or PAM circuit) even when a higher number of poles is selected on Mains are operated over-synchronously as a generator if the Fan as the corresponding wind turbine Torque delivers.
Da eine sogenannte "Pitchregelung" (Mechanische Schaufel- oder Blattverstellung) als Anlaufhilfe recht aufwendig ist, wird der Ventilatormotor wahlweise auch als Anlaufhilfe verwendet.Since a so-called "pitch control" (mechanical blade or blade adjustment) as start-up aid is quite complex, the fan motor can also be used as a starting aid used.
Natürlich lassen sich auch andere elektrische Maschinen hierzu verwenden (Gasch: Windkraftanlagen, S. 240 f). Mit steigendem leistungselektronischem Aufwand ergeben sich dann bessere Regelungsmöglichkeiten.Of course, other electrical machines can also be used use for this (Gasch: wind turbines, p. 240 f). Result with increasing power electronics effort then better control options.
Der Ventilatormotor kann im netzgetrennten Zustand auch als Tachogenerator benutzt werden. Falls der gewählte Antriebsmotor keine Gleichstrom- oder Permanenterregung besitzt, wie beispielsweise der obenerwähnte asynchrone Kurzschlußläufer, kann durch einen definierten Gleichstrom durch die vom Netz getrennte Drehstromwicklung der Motor bis zum Stillstand abgebremst und ein definierter Remanenzmagnetismus im Stillstand erzeugt werden, so daß die Maschine im Leerlauf auch als Tachogenerator der Betriebsführung dienen kann.The fan motor can also be used as a mains disconnected Tachometer generator can be used. If the selected drive motor has no DC or permanent excitation like for example the above-mentioned asynchronous short-circuit rotor, can by a defined direct current through the disconnected three-phase winding of the motor up to Standstill slowed down and a defined remanence magnetism are generated at a standstill so that the machine in idle mode also as a tachometer generator for management can serve.
Falls eine Betriebsführung mittels programmgesteuerter Elektronik vorgesehen ist, kann mit ihr nicht nur der Gewinn elektrischer Energie in der Betriebsart "Windkraftanlage" maximiert werden, sondern auch der Verbrauch elektrischer Energie in der Betriebsart "Ventilator" minimiert werden.In the case of operational management using program-controlled Electronics is provided, it can not only profit electrical energy in the operating mode "wind turbine" be maximized, but also consumption electrical energy in the operating mode "fan" be minimized.
Bei Heubelüftungsanlagen können hierbei Größen wie Lufttemperatur, relative Luftfeuchtigkeit und Temperatur, Verdichtung und Feuchtigkeitsgehalt des zu belüftenden Heustockes für die Berechnung eines optimalen und damit energiesparenden Belüftungsprogrammes dienen. Überdies ist eine genaue und fortlaufende Erfassung der Heustocktemperatur mittels mehrerer mit Sonden an den kritischen Stellen des Heustockes plazierter Temperatursensoren der beste Brandschutz. Die Betriebsführung könnte hierbei zur Ausgabe geeigneter Warnmeldungen dienen.For hay ventilation systems, sizes such as Air temperature, relative humidity and Temperature, compression and moisture content of the to aerating haystack for the calculation of an optimal and thus serve an energy-saving ventilation program. Furthermore, an accurate and ongoing record of the Haystack temperature by means of several with probes on the critical points of the haystack of placed temperature sensors the best fire protection. The management could serve to issue suitable warning messages.
