Abstract

Vorrichtung zur Speicherung von Druckluft in Druckluftbehälter, welche sich in den offenen und geschlossenen Gründungsstrukturen, Schwimm- und Tauchkörpern, einer Offshore-Windkraftanlage befinden, dadurch gekennzeichnet, dass ein Kompressor (2) die erzeugte Druckluft mittels eines Rohrleitungssystems (7) im inneren des Turms nach unten in die Schwimm- und Tauchplattformen oder Schwimmkörpern führt, dort in die/den dafür vorgesehene/n Druckluftbehälter (8) speist und die gespeicherte Druckluft über eine Niederdruckturbine (4), an die ein Generator angeschlossen ist, in Form von elektrischer Energie ins Stromnetz einspeist.Device for storing compressed air in compressed air tanks, which are located in the open and closed foundation structures, floating and immersion bodies, an offshore wind power plant, characterized in that a compressor (2) the compressed air generated by means of a pipeline system (7) inside the tower leads down into the swimming and diving platforms or floating bodies, there feeds into the compressed air tank (8) provided for this purpose and the stored compressed air into the Grid feeds.

Description

Die Vorrichtung betrifft eine Offshore-Windkraftanlage, welche über offene und geschlossenen Gründungsstrukturen, Schwimm- und Tauchkörpern, zwecks Auftrieb und Stabilität mit dem Meeresboden verbunden ist.The device relates to an offshore wind turbine, which is connected via open and closed foundation structures, swimming and diving bodies, for the purpose of buoyancy and stability with the seabed.

Eine Bereitstellung von erzeugter elektrischer Energie ist vom Windaufkommen abhängig und somit ist ein annähernd gleichbleibendes Energieniveau über eine lange Zeit nicht gewährleistet. Die überschüssige Energie der Windkraftanlagen aus Niederlastzeiten soll derzeit an Land in Druckluft umgeformt werden, um sie dann in Kavernen zu speichern; vgl. BINE Informationsdienst. Projektinfo 05/2007. Online in Internet: URL: http://www.bine.info/hauptnavigation/publikationen/projektinfos/publikation/druckluftspeicher-kraftwerke/ [Stand 08.07.2012]. Dies ist mit möglichen geologischen Risiken verbunden. Unvorhergesehene geologische Veränderungen könnten den Standort unbrauchbar machen, da Druckluft entweicht und somit der Nutzen verringert wird.A supply of generated electrical energy is dependent on the wind and thus an approximately constant energy level over a long time is not guaranteed. The excess energy of wind turbines from low load times is currently being converted into compressed air on land, to be stored in caverns; see. BINE information service. Project Info 05/2007. Online in Internet: URL: http://www.bine.info/hauptnavigation/publikationen/projektinfos/publikation/druckluftspeicher-kraftwerke/ [As of 08.07.2012]. This is associated with potential geological risks. Unforeseen geological changes could make the site unusable, as compressed air escapes and thus the benefits are reduced.

Die Vorrichtung ist eine Möglichkeit, die überschüssig erzeugte Energie der Niederlastzeiten in Energiespeichern zu übertragen. Dies geschieht mittels Druckluft.The device is a way to transfer the excessively generated energy of the low load periods in energy storage. This is done by means of compressed air.

Die Druckluftspeicherung besteht aus drei Teilen, siehe Zeichnung 1: Kompressor (2), Rohrleitungssystem (7) mit Druckluftbehälter (8) und Niederdruckturbine mit Generator (4). Die folgenden Erläuterungen beziehen sich auf die Zeichnung 1. Der erste Teil ist der Kompressor (2), der Außenluft (1) ansaugt und einem Rohrleitungssystem (7) zuführt. Der Kompressor befindet sich innerhalb des Turmes der Offshore-Windkraftanlage. Er kann erhöht im Turm, unterhalb der Gondel, oder am Fuß des Turmes eingerichtet werden. Der zweite Teil ist das Rohrleitungssystem (7) mit Druckluftbehälter (8). Es besteht aus einer Hauptröhre, über die die Außenluft (1) in den Druckluftbehälter (8) geführt wird. In der Hauptröhre vor dem Kompressor (2) befindet sich das erste Absperrventil (3). Dieses Ventil schließt die Hauptröhre, damit die Druckluft nicht entweicht, sofern der Kompressor über kein eigenes Sicherheitsventil verfügt. Es kann auch ein Rückschlagventil verwendet werden. Der Druckluftbehälter (8) befindet sich in den Schwimm- und Tauchkörpern der Offshore-Windkraftanlage. Der dritte Teil ist die Niederdruckturbine (4), die mit einem Generator verbunden ist. Von der Hauptröhre geht ein Nebenrohr auf Höhe der Niederdruckturbine ab und verbindet die Turbine (4) mit dem Druckluftbehälter (8). In dem Nebenrohr zur Niederdruckturbine (4) befindet sich das zweite Absperrventil (6), welches die Niederdruckturbine (4) von der Hauptröhre trennt, wenn Außenluft (1) in den Druckluftbehälter (8) gepumpt wird.The compressed air storage consists of three parts, see drawing 1: compressor ( 2 ), Piping system ( 7 ) with compressed air tank ( 8th ) and low-pressure turbine with generator ( 4 ). The following explanations refer to drawing 1. The first part is the compressor ( 2 ), the outside air ( 1 ) and a piping system ( 7 ) feeds. The compressor is located inside the tower of the offshore wind turbine. It can be raised in the tower, below the gondola, or set up at the foot of the tower. The second part is the piping system ( 7 ) with compressed air tank ( 8th ). It consists of a main tube through which the outside air ( 1 ) in the compressed air tank ( 8th ) to be led. In the main tube in front of the compressor ( 2 ) is the first shut-off valve ( 3 ). This valve closes the main tube so that the compressed air does not escape unless the compressor has its own safety valve. A non-return valve can also be used. The compressed air tank ( 8th ) is located in the floating and diving bodies of the offshore wind turbine. The third part is the low-pressure turbine ( 4 ), which is connected to a generator. From the main tube a secondary pipe goes off at the height of the low-pressure turbine and connects the turbine ( 4 ) with the compressed air tank ( 8th ). In the secondary pipe to the low-pressure turbine ( 4 ) is the second shut-off valve ( 6 ), which the low-pressure turbine ( 4 ) separates from the main tube when outside air ( 1 ) in the compressed air tank ( 8th ) is pumped.

Die Turbine (4) wandelt die Luftströmung der ausgelassenen gespeicherten Druckluft in Rotationsenergie, mechanische Energie, um und entlässt die Luft über den Auslass (5). An die Turbinenwelle ist ein Generator angeschlossen, der elektrischen Strom erzeugt. Dieser elektrische Strom wird dem Stromnetz zugeführt.The turbine ( 4 ) converts the air flow of the stored stored compressed air into rotational energy, mechanical energy, and releases the air through the outlet ( 5 ). To the turbine shaft, a generator is connected, which generates electricity. This electrical power is supplied to the power grid.

Der Nutzen der Erfindung zeigt sich bei Höchstlastzeiten in den Zeiten um ca. 11–13 Uhr und um ca. 16–19 Uhr. Mehr Elektrische Energie wird aus dem Energieversorgungsnetz gefordert. Die vorab gespeicherte Druckluft wird über eine Niederdruckturbine geführt. Ein über die Turbine antreibbarer Generator erzeugt die ins Energieversorgungsnetz einzuspeisende elektrische Energie. Dadurch wird bei geringerem oder fehlendem Windaufkommen eine weitere Energieerzeugung geboten und bietet zusätzliche eine Form der dezentrale Energiespeicherung. Ferner wird dadurch das Abschalten der Windkraftanlage für eine bestimmte Zeit verhindert.The benefit of the invention shows at peak load times in the times at about 11-13 clock and at 16-19 clock. More electrical energy is required from the power grid. The pre-stored compressed air is passed through a low-pressure turbine. A generator which can be driven via the turbine generates the electrical energy to be fed into the energy supply network. As a result, with less or no windfall, a further generation of energy is offered and additionally offers a form of decentralized energy storage. Furthermore, this prevents the shutdown of the wind turbine for a certain time.

Die Vorrichtung ist eine Möglichkeit die gespeicherte und die erzeugte Energie der Offshore-Windkraftanlage zu allen Zeiten als Regelenergie anzubieten.The device is a way to offer the stored and generated energy of the offshore wind turbine at all times as control energy.

Zu den Windkraftanlagen gibt es Umspann-, Trafo- und Serviceplattformen deren Gründungs-, Tauch- und Schwimmstrukturen ebenfalls als Druckluftspeicher genutzt werden können.There are transformer, transformer and service platforms for the wind turbines whose founding, diving and floating structures can also be used as compressed air reservoirs.
