Description
Die Erfindung betrifft eine Wasserkraftanlage, deren elektrische Maschine über einen Umrichter mit dem Übertragungsnetz verbunden ist, wobei mit dem Gleichstromzwischenkreis des Umrichters ein Batteriespeicher verbunden ist.The invention relates to a water power plant, the electrical machine of which is connected to the transmission network via a converter, a battery storage device being connected to the DC link of the converter.
Solche Wasserkraftanlagen sind aus dem Stand der Technik bekannt. So offenbart die
Die Aufgabe der Erfindung ist es, eine solche Wasserkraftanlage anzugeben, bei der die Einbindung des Batteriespeichers und die Steuerung des Energieflusses in und aus dem Batteriespeicher flexibler gestaltet sind.The object of the invention is to specify such a hydropower plant in which the integration of the battery store and the control of the energy flow into and out of the battery store are designed to be more flexible.
Die Aufgabe wird erfindungsgemäß durch eine Ausführung entsprechend Anspruch 1 gelöst. Weitere vorteilhafte Merkmale der erfindungsgemäßen Ausführung finden sich in den Unteransprüchen.The object is achieved according to the invention by an embodiment according to
Die erfindungsgemäße Lösung wird nachfolgend anhand von Figuren erläutert. Darin ist im Einzelnen folgendes dargestellt:
-
1 Erfindungsgemäße Wasserkraftanlage.
-
1 Hydroelectric power plant according to the invention.
Der Umrichter umfasst einen netzseitigen Umrichter, welcher mit
Die Wasserkraftanlage
Die Wasserkraftanlage
Bei der elektrischen Maschine kann es sich um eine Asynchronmaschine handeln, wobei der maschinenseitige Umrichter in diesem Fall mit dem Rotor derselben verbunden ist. Bei der elektrischen Maschine kann es sich um eine Synchronmaschine handeln, wobei der maschinenseitige Umrichter in diesem Fall mit dem Stator derselben verbunden ist. Die hydraulische Maschine kann als Turbine, Pumpe oder Pumpturbine ausgebildet sein.The electrical machine can be an asynchronous machine, the machine-side converter in this case being connected to its rotor. The electrical machine can be a synchronous machine, the machine-side converter in this case being connected to its stator. The hydraulic machine can be designed as a turbine, pump or pump turbine.
Neben der flexiblen Leistungsregelung ermöglicht die erfindungsgemäße Wasserkraftanlage die einfache Einbindung von vielen verschiedenen Batteriesystemen, da der Hochsetz-Tiefsetzsteller eine Spannungsanpassung zwischen dem Gleichstromzwischenkreis und dem Batteriesystem erlaubt. Das ist insbesondere deswegen von Vorteil, weil das Batteriesystem eine deutlich geringere Lebensdauer hat als eine Wasserkraftanlage, welche in der Regel für weit mehr als 20 Jahre ausgelegt wird. Das Bedeutet, dass das Batteriesystem während der Lebensdauer der Wasserkraftanlage immer wieder ersetzt werden muss. Bei der rasanten Entwicklung der Batterietechnologie ist zu erwarten, dass in Zukunft standardisierte Batteriesysteme mit besserem Preis-Leistungsverhältnis zur Verfügung stehen werden. Dabei ist es unwahrscheinlich, dass dieselben 100% kompatibel zu einem älteren bestehenden System sein werden, das es zu ersetzen gilt. Die erfindungsgemäße Anordnung ermöglicht die problemlose Einbindung von Batteriesystemen mit unterschiedlichem Spannungsniveau.In addition to flexible power regulation, the hydropower plant according to the invention enables the simple integration of many different battery systems, since the step-up / step-down converter allows the voltage to be adjusted between the DC link and the battery system. This is particularly advantageous because the battery system has a significantly shorter service life than a hydropower plant, which is usually designed for well over 20 years. This means that the battery system has to be replaced again and again during the life of the hydropower plant. With the rapid development of battery technology, it is to be expected that standardized battery systems with a better price-performance ratio will be available in the future. It is unlikely that they will be 100% compatible with an older existing system to be replaced. The arrangement according to the invention enables the problem-free integration of battery systems with different voltage levels.
