Description

Anordnung zur Urtardrückung von beim Synchronisieren von dreiphasi@en Konstant-Spannungsgeneratoren mit Schwungradantrieb auftretenden Strom- und Spannungsschvankungen In manchen Industrieanlagen sind zur Stromversorgung oder Notstromversorgung von Steuereinrichtungen Umformersätze bzw.Arrangement for the original compression of when synchronizing three-phase Constant voltage generators with flywheel drive occur current and voltage fluctuations In some industrial plants, for power supply or emergency power supply of Control devices, converter sets or

Notstromaggregate mit Schwungradantrieb eingesetzt, deren Konstantspannungsgeneratoren betriebsmäßig parallelgeschaltet sind. Bein Synchronisieren der Generatoren treten Stromschwankungen und dadurch bedingte Spannungserhöhungen auf, die zu einer Abschaltung der an die Generatoren angeschlossenen Steuereinrichtungen führen und insbesondere bei elektronisch arbeitenden Steuereinrichtungen erhebliche Störungen nach sich ziehen können.Emergency power generators with flywheel drive are used, their constant voltage generators are operationally connected in parallel. Step on the synchronization of the generators Current fluctuations and the resulting voltage increases that lead to a shutdown the control devices connected to the generators and in particular with electronically operating control devices considerable disruptions can pull.

Diese Schwierigkeiten werden gemäß der Erfindung dadurch vermieden, daß die Ströme in einer der Wicklungen jedes in den Konstantspannungsgeräten enthaltenen Transformators während der Dauer des Synchronisiervorganges den Strömen in den anderen Wieklungen des Transformators entgegengesetzt gerichtet sind. Bei zweiphasig belasteten Konstant-Spannungsgeneratoren ist die ein@ Wicklung jedes Transform@to@s der jeweils unbe-@as@@ @en Phase zugeordnet und die unbelasteten Phasen sind während des Synchronisiervorganges und auch betriebsmäßig miteinander verbunden.According to the invention, these difficulties are avoided by that the currents in one of the windings each contained in the constant voltage devices Transformer feeds the currents into the other for the duration of the synchronization process Wieklungen of the transformer are directed in the opposite direction. With two-phase loads Constant voltage generators is the one winding of each transform @ to @ s of the respective unloaded @ as @@ @en phase and the unloaded phases are during the synchronization process and also operationally connected to each other.

Zur weiteren Erlä@terung wird auf die Zeichnung verwiesen, in der ein Ausführungsbeispiel der erfindungsgemäßen Anordnung sche@atisch dargestellt ist.For further explanation, reference is made to the drawing in which an embodiment of the arrangement according to the invention is shown schematically is.

Die in der Zeichnung dargestellten Drehstromgeneratoren 1 und 2, die beispielsweise in je @inem Schwungrad-Umform@rsatz angeordnet sind, arbeiten über je ein Konstant-Spannungage-@ä@ 3 bzw. 4 und einen Schalter 5 bzw. 6 auf ein zweiphasiges Netz 7. Die Antriebsmotoren der Generatoren 1 und 2 sind beispielsweise an ein Netz mit einer Spannung von 500 V schlossen, während die Spannung des Netzes 7 beispielsweise 220 V beträgt; und zur zweiphasigen Speisung von beispielsweise elektronische Bauelemente enthaltenden Steuerkreisen dient. Die Konstantspannungsgeräte 3 und 4 enthalten j-e einen Transformator mit den Primärwicklungen 8 bis 10 und den Sckundärwieklungen 11. An die Sekundärwicklungen 11 ist je ein Gleichrichtersatz 12 angeschlossen, der gleichstromseitig mit der Erregerwicklung des Generators 1 bzw. 2 und im Parallelbetrieb über je einen mit dein Schalter 5 bw. 6 gekoppelten Hilfsschalter 13 bzw. 14 mit den Erregerwicklungen beider Generatoren verbunden ist. Die Primärwicklungen 10 beider Transformatoren sind über die Schalter 5 und 6 derart miteinander und mit der Klemme W- beider Generatoren verbunden, daß ein während des Parallelschaltvorganges in den betriebsmäßig unbelasteten Phasen W fließender Strom den Strömen i den belasteten Phasen U und V entgegengesetzt gerichtet ist.The three-phase generators 1 and 2 shown in the drawing, the For example, they are each arranged in a flywheel converter set, work over One constant-voltage stage @ ä @ 3 or 4 and a switch 5 or 6 on a two-phase network 7. The drive motors of the generators 1 and 2 are connected to a network, for example a voltage of 500 V closed, while the voltage of the network 7, for example Is 220 V; and for two-phase supply of electronic components, for example containing control circuits is used. The constant voltage devices 3 and 4 contain j-e a transformer with the primary windings 8 to 10 and the Sckundärwieklungen 11. A rectifier set 12 is connected to each of the secondary windings 11, the DC side with the excitation winding of generator 1 or 2 and in parallel operation about one with your switch 5 bw. 6 coupled auxiliary switch 13 or 14 with is connected to the excitation windings of both generators. The primary windings 10 both transformers are via the switches 5 and 6 in such a way with each other and with connected to terminal W of both generators, that one during the parallel switching process in the operationally unloaded phases W current flowing to the currents i the loaded Phases U and V are directed in opposite directions.

Diese Stromrichtung wirkt sieh nur wahrend des Ausgleichsvorganges aus, da in der unbelasteten Phase W im Normalbetrieb kein Strom fließt. Infolge der Herabsetzung der Erregerspannung für den parallel zu schaltenden Generator während des Ausgleichsvorganges treten liii Netz 7 nur noci für die angeschlossenen Stromkreise unschädliche Spannungserhöhungen auf.This direction of current is only effective during the equalization process off, since no current flows in the unloaded phase W during normal operation. As a result the reduction of the excitation voltage for the generator to be connected in parallel during the equalization process occurs liii network 7 only noci for the connected circuits harmless voltage increases.

Bei dreiphasig belasteten Generatoren wird vorteilhafterweise je eine der Primärwicklungen der Transformatoren an einen Umschalter angeschlossen, der die Anschlüsse dieser Wicklungen während des Ausgleichsvorganges umpolt. Anstelle d L' r polung je einer Wicklung der Transformatoren kann je ein zusätzliche Transformatorwicklung vorgesehen sein.In the case of three-phase loaded generators, one each is advantageously the primary windings of the transformers are connected to a changeover switch, the reverse the polarity of the connections of these windings during the balancing process. Instead of The polarity of each winding of the transformers can be an additional transformer winding be provided.
