Description
Einrichtung zum Parallelbetrieb eines odermehrerer kompoundierter Maschinenumformer mit gittergesteuerten Stromrichtern bei gleichbleibender Belastungsverteilung Auf dem Gebiet der Umwandlung von Wechselstrom in Gleichstrom werden bekanntlich Quecksilberdampfgleichrichter den umlaufenden Umformern vielfach vorgezogen. Abgesehen von den Fällen verhältnismäßig niedriger Gleichspannung behauptete sich der umlaufende Umformer dort, wo kompoundierte und überkompoundierte Umformeranlagen erweitert werden sollten. Die Kompoundierung von umlaufenden Gleichstrommaschinen oder Einankerumfarmern spricht so schnell an, daß. die zur Spannungsregelung von Gleichrichtern früher benutzten Einrichtungen, z. B. Stufentransformatoren oder Induktionsregler, zeitlich mit der *Wirkung der Kompoundwicklungen nicht Schritt halben konnten.Device for parallel operation of one or more compounded Machine converter with grid-controlled converters with constant load distribution In the field of converting alternating current to direct current, it is known Mercury vapor rectifiers are often preferred to rotating converters. Apart from that of the cases of comparatively low DC voltage, the circulating one held its own Converters where compounded and overcompounded converter plants are expanding should be. The compounding of rotating DC machines or single-armature hugs responds so quickly that. those used to regulate the voltage of rectifiers facilities used, e.g. B. step transformers or induction regulators, temporally could not keep up with the * effect of the compound windings.
Mit der neueren Entwicklung einer Gleichrichterspannungsregelung durch- Gittersteuerung ist eine solche Beschleunigung des Regelvorganges.' erreichbar .geworden, daß die Regelgeschwindigkeit des Gleichrichters praktisch die gleiche ist wie diejenige einer kompoundierten Gleichstrommaschine oder eines kompoundierten Einankerumformers. Bei dem Parallelarbeiten gittergesteuerter Gleichrichter mit an die gleiche Sammelschiene angeschlossenen kompoundierben oder überkompoundierten Maschinen entstehen je- doch bezüglich der Lastverteilung zwischen Gleichrichter und Maschine Schwierigkeiten.With the more recent development of rectifier voltage regulation by grid control, such an acceleration of the regulation process is possible. ' achievable that the control speed of the rectifier is practically the same as that of a compounded DC machine or a compounded single armature converter. When grid-controlled rectifiers work in parallel with compounding or overcompounding machines connected to the same busbar, however, difficulties arise with regard to the load distribution between the rectifier and the machine.
Aufgabe der Erfindung ist es, auch für Maschinenumformer und Gleichrichter die Möglichkeit des Parallelarbeitens bei gleichbleibender Belastungsverteilung zu schaffen. Gemäß der Erfindung werden zu dem Zweck die zur Steuerung der gittergesteuerten Gleichrichter dienenden Relais bzw. Relaisstromkreis:e zu den KompoundwIcklungen der Maschinenumformer parallel geschaltet. Die Relais bzw. Relaisstromkreise werden dabei hinsichtlich ihrer Ohmschen und induktiven Widerstände mit den @entsprechenden Werten der Kompoundwicklungen dem geforderten Belastungsanteil entsprechend abgeglichen. Sind mehrere Maschinenumformer in ein und derselben Anlage vorhanden, so werden die Kompoundwicklung.en dieser Maschinen zweckmäßig durch eine Ausgleichsschiene verbunden, welche die Parallelschaltung aller Kompoundwicklüngen bewirkt, und die Regelrelais der Steuergleichrichter werden zwischen die verlängerte Ausgleichssammelschiene der Kompoundwicklungen und die, Hauptsammelschiene angeschlossen.The object of the invention is also for machine converters and rectifiers the possibility of parallel work with constant load distribution to accomplish. According to the invention for the purpose of controlling the grid-controlled Rectifier-serving relays or relay circuits: e to the compound windings the machine converter connected in parallel. The relays or relay circuits are with regard to their ohmic and inductive resistances with the @ corresponding The values of the compound windings are adjusted according to the required load share. If there are several machine converters in one and the same system, the Kompoundwick.en these machines expediently by a compensating rail connected, which causes the parallel connection of all Kompoundwicklüngen, and the Control relays of the control rectifiers are placed between the extended compensation busbar the compound windings and the main busbar connected.
Die Wirkungsweise der Anordnung nach der Erfindung ist folgende: Tritt beispielsweise eine Zunahme der Netzbelastung ein, so möge diese Zunahme zunächst einmal von dem Gleichrichter gedeckt werden. Der Mehrstrom fließt aber infolge der Ausgleichssammelschiene nicht allein durch die Wicklung des Gleichrichterregelrelais, sondern er verteilt sich den Ohmschen und induktiven Widerständen entsprechend auch auf die parallel geschalteten Relais bzw. Kompoundwicklungen und bewirkt dadurch eine entsprechende gleichmäßige Erhöhung der Spannung bei allen parallel arbeitenden Gleichstromerzeugern. Der umgekehrte Vorgang spielt sich bei Stromrückgang ab.The mode of operation of the arrangement according to the invention is as follows: Step for example an increase in the network load, so may this increase first once covered by the rectifier. The additional current flows as a result of the Compensating busbar not only through the winding of the rectifier control relay, rather, it is distributed between ohmic and inductive Resistances accordingly also on the relays or compound windings connected in parallel and thereby causes a corresponding even increase in tension in all DC generators working in parallel. The reverse process plays a role Decrease in current.
Die Anordnung nach der Erfindung hat den Vorteil, daß Gleichrichter mit kompoundierten Maschinenumformern einwandfrei parallel arbeiten können, und daß es daher möglich ist, in bestehenden Anlagen zu den vorhandenen kompoundierten Maschinenumformern als Erweiterung der Anlage Steuergleichrichter aufzustellen.The arrangement according to the invention has the advantage that rectifier can work perfectly in parallel with compounded machine converters, and that it is therefore possible to use the existing compounded in existing plants To set up machine converters as an extension of the control rectifier system.
