Description

Anordnung zur Regelung der Phasenkompensation in Wechselstromnetzen mittels Asynchronmaschinen .mit Kommutatorphasenschieber nach Patent 394529. Im Hauptpatent ist eine Anordnung zur Regelung von Asynchronmaschinen mittels an die Rotorkreise angeschlossener Kollektorhintermaschine beschrieben, bei der die Asynchronmaschine durch Erregung mittels Netzfrequenz oder annähernd Netzfrequenz durch den Synchronismus gebracht werden kann, und ,die dadurch gekennzeichnet ist, dali die Ständeramperewindungen der Kollektorhintermaschine zum, Zwecke einer beliebigen Einstellung ihres Eigenantriebes gesondert geregelt werden. Die Erfindung betrifft die Verwendung dieser Anordnung zur Phasenkompensation in Wechselstromnetzen. Zu diesem Zwecke wird,der Ständer .der Vordermaschine in Reihe zwischen Energieabgabe- und -aufnahmestelle eines Netzes geschaltet. Der Vorteil der Verwendung dieses Maschinensatzes besteht darin, ,daß er das zu seinem Antrieb erforderliche Drehmoment selbst liefert, so daß ein besonderer Antriebsmotor nicht erforderlich ist.Arrangement for regulating the phase compensation in AC networks by means of asynchronous machines .with commutator phase shifter according to patent 394529. Im The main patent is an arrangement for regulating asynchronous machines by means of the Rotor circuits connected collector rear machine described in which the asynchronous machine by excitation by means of mains frequency or approximately mains frequency through synchronism can be brought, and, which is characterized, dali the stator ampere turns the collector rear machine for the purpose of any setting theirs Self-propelled to be regulated separately. The invention relates to the use this arrangement for phase compensation in AC networks. To this end is, the stand. of the front machine in series between the energy delivery and absorption point of a network. The advantage of using this machine set is there in that it supplies the torque required to drive it itself, so that a special drive motor is not required.

Ein Ausführungsbeispiel der Erfindung, ist in der Zeichnung veranschaulicht. b bedeutet die Vordermaschine, .die als Asynchronmaschine ausgeführt ist, und deren Ständerwicklung in Reihe mit dem Einphasen- oder Mehrphasennetz a liegt. An den Rotorkreis der Asynchronmaschine ist über die Schleifringe c der Ständerkreis e des Kommutatorphasenschiebers d angeschlossen; die Erregung erfolgt durch die Schleifringe g über den gegebenenfalls regelbaren Transformator k aus dem Netze a. Die Ständerwicklung ist zum Zwecke des Selbstantriebes mit regelbaren (beispielsweise mit Hilfe des Widerstandes r) Amperewindungen ausgeführt, wie dies bereits im Hauptpatent beschrieben ist. Durch Veränderung des Widerstandes r hat man es völlig in der Hand, die Kollektormaschine d so einzustellen, daß sie vom Netz aus erregt als ständergespeister Asynchronmotor anläuft und die mit ihr gekuppelte Asynchronmaschine antreibt. Die Kompensation des Netzes wird durch Einstellung der Erregung der Kollektormaschine, beispielsweise mit Hilfe des Transformators k, geregelt.An embodiment of the invention is illustrated in the drawing. b means the front machine, which is designed as an asynchronous machine, and its Stator winding is in series with the single-phase or multi-phase network a. To the The rotor circuit of the asynchronous machine is the stator circuit e via the slip rings c of the commutator phase shifter d connected; the excitation takes place through the slip rings g via the optionally controllable transformer k from the network a. The stator winding is for the purpose of self-propulsion with controllable (for example with the help of the Resistance r) ampere turns carried out, as already described in the main patent is. By changing the resistance r you have it completely in your hand, the collector machine d to be set so that it is excited from the mains as a stator-fed asynchronous motor starts up and drives the asynchronous machine coupled to it. The compensation the network is set by setting the excitation of the collector machine, for example with the help of the transformer k, regulated.

An Stelle der Phasenwicklung mit regelbarer Amperewindungs.zahl kann im Ständer ein besonderer Käfig zur Entwicklung der mechanischen Antriebsenergie angeordnet werden.Instead of the phase winding with an adjustable number of ampere turns a special cage in the stand for developing the mechanical drive energy to be ordered.

Bei Maschinensätzen zur Kompensation von Einphasennetzen ist mit der Käfigwicklung noch der besondere Vorteil verbunden, daß die Erregung des Phasenschiebers d nunmehreinphasig erfolgen kann, weil durch die Käfigwicklung das erforderliche Erregerdrehfeld in der Kommutatormaschine erzeugt wird. Das Drehfeld kann bei Einphasenmaschinen auch dadurch erzeugt werden, daß die Kompensationswicklung des Ständers * mehrphasig kurzgeschlossen wird.In the case of machine blocks for the compensation of single-phase networks, the Cage winding still has the particular advantage that the excitation of the phase shifter d can now be carried out in multiple phases, because the cage winding provides the necessary Exciter rotating field is generated in the commutator machine. The rotating field can be used in single-phase machines can also be generated by the fact that the compensation winding of the stator * is multiphase is short-circuited.
