Description
Anordnung zur Regelung von Asynchronmaschinen mittels an die Rotorkreise angeschlossener Hintermaschinen. In dem Patent 3912o¢ sind fremderregte Regelsätze beschrieben, bei denen eine Asyn-. chronmaschine mittels einer an die Rotorkreise angeschlossenen Kollektorhintermaschine geregelt wird, deren Erregung mittels einer Synchronmaschine erfolgt. Insbesondere ist ein Beispiel angeführt, bei dem die Hintermaschine mit der Hauptmaschine mechanisch gekuppelt ist und die Synchronerregermaschine durch einen Synchronmotor angetrieben wird. Beide Synchronmaschinen bedürfen einer Gleichstromquelle. Steht eine solche Quelle nicht zur Verfügung, so muß noch ein besonderer Drehstrom-Gleichstromumformer angeordnet werden, der die zur Erregung der beiden Synchronmaschinen notwendige Gleichstromenergie liefert. Hierdurch wird aber die Zahl der Hilfsmaschinen unerwünscht erhöht.Arrangement for the regulation of asynchronous machines by means of the rotor circuits connected rear machines. In the 3912o ¢ patent there are separately excited rule sets described in which an asyn-. chron machine by means of a to the rotor circles connected collector rear machine is regulated, the excitation of which by means of a Synchronous machine takes place. In particular, an example is given in which the rear machine is mechanically coupled to the main machine and the synchronous exciter through a synchronous motor is driven. Both synchronous machines require a direct current source. Is there a Such a source is not available, so there must be a special one Three-phase DC converter are arranged, which is used to excite the two Synchronous machines supplies the necessary direct current energy. But this is the The number of auxiliary machines increased undesirably.
Dies kann nach der Erfindung vermieden werden, wenn als Antriebsmotor für die Synchronerregermaschine ein Einankerumformer verwendet wird, dessen Gleichstromseite die Gleichstromerregerenergie für die Synchronerregermaschine liefert. Ein Ausführungsbeispiel hierfür-ist in der Zeichnung dargestellt. Mit a ist das Drehstromnetz, aus dem die Asynchronma'schine b gespeist wird, bezeichnet. An die Schleifringe c ist die Kollektorhintermaschine d mit dem Ständer e und dem Kollektor f angeschlossen. Die Hintermaschine wird über die Schleifringe g der Kollektorma.schine und Y der Synchronmaschine h von dieser erregt. Nach der Erfindung wird diese Maschine von einem Einankerumformer u angetrieben, der seine Energie aus dem Netz a, im vorliegenden Falle über den Transorma.tor i und die Schleifringe s erhält. Gleich. zeitig liefert der Umformer von seinem Kollektor k aus über die Leitungen 1 den Erregerstrom in die Erregerwicklung w der Synchronmaschine h sowie in seine eigene Erregerwicklung v. Er ersetzt damit den Antriebsmotor für die synchrone Erregermaschine h sowie einen Umformersatz für die Erzeugung des für Synchrongenerator und -motor erforderlichen Gleichstroms.According to the invention, this can be avoided if a single armature converter is used as the drive motor for the synchronous exciter, the DC side of which supplies the direct current exciter energy for the synchronous exciter. An exemplary embodiment for this is shown in the drawing. The three-phase network from which the asynchronous machine b is fed is denoted by a. The collector rear machine d with the stator e and the collector f is connected to the slip rings c. The rear machine is excited by this via the slip rings g of the Kollektorma.schine and Y of the synchronous machine h. According to the invention, this machine is driven by a single armature converter u, which receives its energy from the network a, in the present case via the Transorma.tor i and the slip rings s. Same. At the same time, the converter supplies the excitation current from its collector k via the lines 1 to the excitation winding w of the synchronous machine h and to its own excitation winding v. It thus replaces the drive motor for the synchronous exciter h as well as a converter replacement for generating the direct current required for the synchronous generator and motor.
Die Erfindung kann sowohl für Regelsätze, die nur die Drehzahl der Hauptmaschine regeln, als auch für Maschinensätze zur Regelung der Phasenverschiebung sowie für Maschinensätze zur Regelung von Drehzahl und Phasenverschiebung mit Vorteil verwendet werden. Die Gleichstromspannung des Einankerumformers kann in bekannter Weise, z. B. durch einen Stufentransformatox oder Drehtransformator geregelt werden.The invention can be used for rule sets that only control the speed of the Control the main machine, as well as for machine blocks to control the phase shift as well as for machine sets for controlling speed and phase shift with advantage be used. The DC voltage of the single armature converter can be known in Way, e.g. B. be regulated by a step transformer or rotary transformer.
