Description
Stand der TechnikState of the art
In den 90e Jahren wurden Busse (Gyrobusse) mit Schwungradspeichern eingesetzt. Es gab und gibt sehr viele Anwendungen in denen Schwungräder als Energiespeicher für elektrische Systeme eingesetzt werden. Diese bestehen aus einem schnell rotierenden Rad, das über einen Motorgenerator die elektrische Energie in seine Drehbewegung umsetzt oder wieder abgibt. Dieses System ist in der Lage, kurzfristig hohe Energiemengen bereitzustellen. Moderne Schwungradspeicher können lokal kurzzeitige Last- und Erzeugungsschwankungen ausgleichen weil sie kurzfristig in breiten Leistungsbereichen regelbar sind. Heutige Schwungräder arbeiten mit Magnetlagern, fast ohne Reibung in Vakuumgehäusen. In der modernen Technik erleben Schwungräder erneut eine Renaissance. Begonnen hat die Entwicklung moderner Schwungradrotoren in den USA für Raumfahrtanwendungen. Für Satelliten und kleine Raumstationen werden Schwungräder als kinetische Energiespeicher zur Überbrückung der Energieversorgung im Erdschatten und gleichzeitig zur Lageregelung eingesetzt. Möglichkeiten von Energiespeicherung existieren auch bei Fahrzeugen, wo die Energie trotz Lastschwankungen, mit wesentlich besserem Wirkungsgrad erzeugt wird. Das Schwungrad kann die gespeicherte kinetische Energie ohne zusätzliche Wirkungsgradverluste abgeben. Dadurch kann die Energieversorgung in jedem Fall sichergestellt und für die Speicherung in Batterien verwendet werden. Das in einer rotierenden Masse Energie gespeichert werden kann, steht wohl außer Frage. Nehmen wir als Beispiel Vijelko Milkowitch mit seinem zweistufigen Oszillator. Er verweist auf einen 12-fachen Energieaustrag (COP 12)!In the 90s, buses (gyro buses) with flywheel stores were used. There were and are very many applications in which flywheels are used as energy storage for electrical systems. These consist of a fast rotating wheel, which converts the electrical energy into its rotary motion via a motor generator or releases it again. This system is capable of providing high levels of energy in the short term. Modern flywheel storage systems can compensate for short-term load and generation fluctuations locally because they can be controlled in broad power ranges at short notice. Today's flywheels work with magnetic bearings, almost without friction in vacuum housings. Flywheels are once again experiencing a renaissance in modern technology. The development of modern flywheel rotors in the USA began for space applications. For satellites and small space stations flywheels are used as kinetic energy storage to bridge the energy supply in the earth's shadow and at the same time to the position control. Possibilities of energy storage also exist in vehicles, where the energy is generated despite load fluctuations, with much better efficiency. The flywheel can deliver the stored kinetic energy without additional efficiency losses. As a result, the power supply can be ensured in any case and used for storage in batteries. That can be stored in a rotating mass of energy is probably out of the question. Take Vijelko Milkowitch as an example with his two-stage oscillator. He points to a 12-fold depletion of energy (COP 12)!
