patent for invention


标题(德语)

Stromrichterschaltungsanordnung und zugehöriges Ansteuerverfahren für Generatoren mit dynamisch veränderlicher Leistungsabgabe


标题(英语)

Power converter apparatus and related driving method for generators with dynamically varying output power


标题(法语)

Convertisseur de puissance pour des générateurs avec puissance variable dynamiquement


摘要(英语)

The device has a first direct connection of the generator (20) to the current network (90) with a switch (30) in each phase and a second connection with a four quadrant converter (100) with at most half the rated power of the generator arranged so that a first current converter (50) has 3 a.c. connections connected to the 3 generator connections and its d.c. connections connected to an intermediate circuit (60) with a capacitor (62) and a second current converter (70) has 3 a.c. connections connected to the current network and its d.c. connections connected to the intermediate circuit. An independent claim is also included for a control method for a current converter circuit arrangement.


摘要(德语)

Die Erfindung beschreibt eine Stromrichterschaltungsanordnung sowie ein zugeordnetes Ansteuerverfahren zur Verbindung eines dreiphasigen Generators (20) mit einem Stromnetz (90), bestehend aus einer ersten direkten Verbindung des Generators (20) mit dem Stromnetz (90) und einer zweiten Verbindung des Generators (20) mit dem Stromnetz (90), wobei hier ein Vierquadrantenumrichter (100) derart angeordnet ist, dass dieser aus einem ersten Stromrichter (50) besteht, dessen drei Wechselspannungsanschlüsse (24) mit den drei Anschlüssen des Generators (20) und einem zweiten Stromrichter (70) besteht, dessen drei Wechselspannungsanschlüsse (26) mit dem Stromnetz (50) verbunden sind. Das Ansteuerverfahren zur Blindleistungskompensation im Falle eines Netzkurzschlusses ist dergestalt, dass in einem ersten Zeitraum nach dem Kurzschluss der netzseitige Stromrichter (70) über seine Wechselspannungsanschlüsse Blindleistung in das Stromnetz abgibt, in einem zweiten Zeitraum der Stromrichter Blindleistung in das Stromnetz zurückspeist und in einem dritten Zeitraum der gesamte Vierquadrantenumrichter (100) den sanften Wiederanlauf ohne Netzbelastung mit Blindleistung des Generators (20) steuert.
