Description
Netzkupplungsumformer für Leistungsübertragung zwischen zwei Wechselstromnetzen bestehen im allgemeinen aus einer Synchronmaschine und einer Asynchronmaschine mit Kommutatorhintermaschine. Es ist auch schon vorgeschlagen worden, beide Hälften des Umformers als asynchrone Kommutatorkaskade auszubilden. Diese letzte Anordnung kann besonders dann vorteilhaft sein, wenn die Frequenzänderungen der beiden Netze außerordentlich groß sind.Network coupling converter for power transmission between two AC networks generally consist of a synchronous machine and an asynchronous machine with a commutator rear machine. It it has also already been proposed that both halves of the converter be used as an asynchronous commutator cascade to train. This last arrangement can be particularly advantageous when the frequency changes of the two Networks are extraordinarily large.

Der Betrieb des Umformers mit konstanter Drehzahl gemäß der Erfindung ermöglicht eine bessere Ausnutzung der Maschinen, aus welchen der Umformer besteht, besonders dann, wenn diese Maschinen mit Eigenbelüftung ausgeführt sind, weil infolge der konstanten Drehzahl die Luftförderung ebenfalls dauernd die gleiche ist. Ein weiterer Vorteil der konstanten Drehzahl ergibt sich bei Umformern, bei denen die eine Hälfte als Konstantleistungskaskade ohne Regler arbeiten soll, wobei die Kommutatorhinter,-maschine mit der Hauptgruppe unmittelbar gekuppelt ist. Solche Konstantleistungskaskaden besitzen bekanntlich sogenannte Fehlerquellen, die zur Folge haben, daß die Leistung bei Frequenzänderungen nicht ganz konstant bleibt, sondern daß Abweichungen der Leistung von dem verlangten Wert auftreten. Eine Fehlerquelle liegt z. B. in der veränderlichen Drehzahl der Kommutatorhintermaschine. Wird nun nach der Erfindung die Umformergruppe auf konstante Drehzahl geregelt, dann verschwindet die betreffende Fehlerquelle, so daß irgendwelche besonderen Vorrichtungen zur Aufhebung dieser Fehlerquelle überflüssig werden.The operation of the converter at constant speed according to the invention enables better utilization of the machines that make up the converter, especially when these machines are designed with self-ventilation, because as a result of the constant Speed, the air delivery is also constantly the same. Another advantage the constant speed results in converters where one half is used as Constant power cascade should work without a controller, with the commutator behind the machine is directly coupled to the main group. Such constant power cascades are known to have so-called sources of error, which have the consequence that the power does not remain completely constant when the frequency changes, but that deviations the performance of the required value occur. One source of error is e.g. B. in the variable speed of the commutator rear machine. Is now according to the invention the converter group is regulated to constant speed, then the relevant one disappears Source of error, so that any special devices for eliminating this source of error are superfluous.
