Description
Es wurde bereits vorgeschlagen, selbstgeführte Umformer, Umrichter, Wechselrichter od.. dgl. für die Umformung von Gleichstrom in Wechselstrom oder Drehstrom in der Weise auszubilden;, daß eine über im Wechselrichterbetrieb arbeitende elektrische Ventile oder Kontakte gespeiste elektrische Maschine, vorzugsweise Synchronmaschine, zur Taktgebung, als Energiespender und gegebenenfalls zur Deckung der Blindleistung dient. Als.It has already been proposed to use self-commutated converters, converters, inverters or the like. For the conversion of direct current into alternating current or three-phase current in such a way; that a Electrical supplied by electrical valves or contacts operating in inverter mode Machine, preferably synchronous machine, for Clock, serves as an energy source and, if necessary, to cover the reactive power. As.
ίο elektrische Ventile werden hierbei vorzugsweise steuerbare Lichtbogenentladungsgefäße verwendet. Diese können nur bis zu einer bestimmten Höhe der Betriebsspannung hergestellt werden; und sind auch für hohe Betriebsspannungen unverhältnis^· mäßig teuer.ίο electric valves are preferred here controllable arc discharge vessels used. These can only be up to a certain height the operating voltage can be established; and are also disproportionate for high operating voltages ^ moderately expensive.
Um derartige selbstgeführte Umformer, Umrichter, Wechselrichter od. dgl. unter Verwendung' einer kollektorlosen Hilfsmaschine mit motorischem Lauf ohne äußeren Antrieb auch für die Umformung von Gleichstrom - Höchstspannung in Drehstrom, Wechselstrom oder niedergespannten Gleichstrom wirtschaftlich herstellen zu können, sollen nach dem Vorschlag der Erfindung Gleich,-richtarelemente der üblichen Bemessung verwendet werden, deren Sperrspannung an sich wesentlich kleiner ist als die gesamte Gleichspannung. Erfindungsgemäß geschieht dies, indem die an sich bekannte Reihenschaltung einzelner Stromrichtergefäßgruppen bzw. Graetzschaltungen angewendet wird. Von diesen ist beispielsweise jede über einen Transformator mit der kollektorlosen Hilfsmaschine verbunden. Man kann, auch innerhalb der Stromrichtergefäßgruppen mehrere Stromrichtergefäße in Reihe schalten»To such self-commutated converters, converters, inverters or the like using ' a brushless auxiliary machine with motorized operation without external drive also for the Conversion of direct current - maximum voltage into three-phase, alternating current or low voltage To be able to produce direct current economically, according to the proposal of the invention, rectifier elements the usual rating are used, the reverse voltage of which is essentially essential is less than the total DC voltage. According to the invention, this is done by the per se known series connection of individual converter vessel groups or Graetz circuits are used will. For example, each of these is connected to the brushless auxiliary machine via a transformer tied together. Several converter vessels can also be used within the converter vessel groups connect in series »
Im folgenden ist die Erfindung an Hand von. Ausführungsbeispielen erläutert.The following is the invention with reference to. Embodiments explained.
Bei der Anordnung nach Fig. 1 liegt zwischen + und — eine Gleichstromhöchstspannung, beispielweise von 200 kV. Dazwischen liegen drei in Reihe angeordnete Gefäßgruppen 1, 2, 3 als Wechselrichteranordnungen in Draiphasen-Graetzschaltung. Auf der Drahstromseite dieser Weichselrichteranordnungen liegen als- Motor laufende und als Energieumformer wirkende Synchronmaschineu 5, 6, 7, die den Taktgeber darstellen und den Blindleistungsbedarf des Verbraucherstromkreises decken.. Dieser ist über Transformatoren 8, 9, 10 an die Wechselstromseite der Wechselrichteranordnungen angeschlossen.In the arrangement according to FIG. 1, a direct current maximum voltage lies between + and -, for example of 200 kV. In between there are three rows of vessel groups 1, 2, 3 as inverter arrangements in draiphase Graetz circuit. On the wire current side of these Weichselrichter arrangements are a synchronous machine running as a motor and acting as an energy converter 5, 6, 7, which represent the clock generator and the reactive power requirement of the consumer circuit cover .. This is via transformers 8, 9, 10 to the alternating current side of the inverter arrangements connected.
Um den Synchronlauf der Maschinen. 5, 6, 7 sicherzustellen, sind in je einer Phase der Sekundärstromkreise der Transformatoren 8, 9, 10 Stromtransformatoren 11. 12, 13 angeordnet, deren Sekundärwicklungen in Reihe geschaltet sind und eine Ausgleichsleitung bilden. Ihre Wirkung besteht darin, daß eine etwa bei einem Transformator auftretende Stromerhöhung sich auf die beiden anderen Transformatoren überträgt und damit ausgleichend wirkt.To ensure that the machines run synchronously. 5, 6, 7 are each in a phase of the secondary circuits of transformers 8, 9, 10 current transformers 11, 12, 13 arranged, whose secondary windings are connected in series and form a compensating line. Your effect consists in the fact that an increase in current that occurs in a transformer, for example, affects the transmits two other transformers and thus has a balancing effect.
Fig. 2 zeigt ein Ausführungsbeispiel, das sich von dem nach Fig. 1 dadurch unterscheidet, daß die Transformatoren 8, 9, 10 jeweils zwischen die Wechselrichteranoirdnung 1, 2, 3 und die kollektorlose Blindleistungsmaschine 5, 6, 7 geschaltet sind. Die Blindleistungsmaschinen 5, 6, 7 liegen hier also* unmittelbar parallel an der Drehstromsammelschiene. Es genügt in diesem Falle auch, statt mehrerer eine einzige Blindleistungsmaschine vorzusehen.Fig. 2 shows an embodiment which differs from that of FIG. 1 in that the transformers 8, 9, 10 each between the inverter assembly 1, 2, 3 and the collectorless Reactive power machine 5, 6, 7 are connected. The reactive power machines 5, 6, 7 are located here * directly parallel to the three-phase busbar. In this case it is also sufficient to provide a single reactive power machine instead of several.
Die gesamte Anordnung arbeitet wie eine Synchronmaschiine, ist also· für Takthaltung (Frequenz) und eigene Blindleistungsdeckung nicht an andere Netze oder EWs gebunden. Andererseits ist die Anordnung beim Parallelbetrieb regelbar wie jede Synchronmaschine. Dies ist z. B. wichtig für Umformerstationen bei Gleichstrom-Hochspannungs-Übertragungsanlagen,. The whole arrangement works like a synchronous machine, is therefore · for clock maintenance (frequency) and own reactive power coverage not on other networks or EWs bound. On the other hand, the arrangement can be regulated like in parallel operation every synchronous machine. This is e.g. B. important for transformer stations in direct current high voltage transmission systems.
