Description
Anordnung zur Spannungsregelung, insbesondere zur Konstanthaltung der Spannung von Synchronmaschinen Die Erfindung bezieht sich auf eine Anordnung zur Spannungsregelung, insbesondere zur Konstanthaltung der Spannung von Synchronmaschinen mittels eines Gleichrichters, der die Erregerwicklung aus dem Wechselstromnetz speist, wobei der Gleichrichterumspanner einerseits vom Belastungsstrom der Synchronmaschine beeinflußt wird und andererseits mit von der Belastung der Synehronn ia;schine unabhängigen Scheinwiderständen in Reihe geschaltet ist. Bei einer bekannten derartigen Anordnung (Harzsche Schaltung) sind als Scheinwiderstände neben Drosseln zusätzlich Kondensatoren an einer vierten Wicklung des Gleichrichtertransformators vorgesehen. Die Drosseln und die Kondensatoren wirken hier auf Wicklungsteile mit gleichen Wicklungsachsen. Diese Schaltung hat den Nachteil, daß der Generator induktiv vorbelastet wird.Arrangement for voltage regulation, especially for keeping it constant the voltage of synchronous machines The invention relates to an arrangement for voltage regulation, especially for keeping the voltage of synchronous machines constant by means of a rectifier that feeds the field winding from the alternating current network, the rectifier converter on the one hand from the load current of the synchronous machine is influenced and, on the other hand, independent of the burden on the Synehronn ia; schine Impedance resistors is connected in series. In a known arrangement of this type In addition to chokes, capacitors are used as apparent resistances (Harz circuit) provided on a fourth winding of the rectifier transformer. The thrushes and the capacitors act here on winding parts with the same winding axes. This circuit has the disadvantage that the generator is inductively biased.
Durch die Erfindung sind diese Schwierigkeiten beseitigt. Erfindungsgemäß sind für jede Phase eine Drossel und ein Kondensator parallel geschaltet und arbeiten auf zwei gegeneinandergeschaltete Primärwicklungen des Gleichrichtertransformators.These difficulties are eliminated by the invention. According to the invention a choke and a capacitor are connected in parallel for each phase and work on two oppositely connected primary windings of the rectifier transformer.
Die Erfindung soll an Hand des in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert werden. 1 ist der Synchrongenerator, dessen Spannung bei verschiedenenLeistungsfaktoren genau gleich gehalten werden soll. Die Erregerwicklung 2 wird über den Gleichrichter 3 von dem GleichricIitertransformator 4 gespeist. Der Primärteil des Gleichrichtertransformators besteht aus zwei gegeneinandergeschalteten Wicklungen 5 und 6. Der einen Wicklung 5 ist in jeder Phase ein Kondensator 7 und der anderen Wicklung 6 eine Drossel 8 vorgeschaltet.The invention is based on the embodiment shown in the drawing are explained in more detail. 1 is the synchronous generator, its voltage at different power factors should be kept exactly the same. The excitation winding 2 is via the rectifier 3 fed by the rectifier transformer 4. The primary part of the rectifier transformer consists of two windings 5 and 6 connected against one another. One winding 5 is a capacitor 7 in each phase and the other winding 6 is a choke 8 upstream.
Die von den Blindkomponenten des Drosselstromes und Kondensatorstromes herrührenden Amperewindungen im Transformator addieren sich algebraisch. Ihre Summe ist infolge der erfindungsgemäßen Schaltung konstant. Die Amperewindungen der Wirkkomponenten der beiden Ströme hingegen, die immer gleich groß sind, heben sich gegenseitig auf. Da also dem Transformator konstante Amperewindungen aufgedrückt werden, kann man auf den gleichen Transformator dem Laststrom proportionale Amperewindungen aufbringen, und die beiden Teile werden sich in ihrer Auswirkung auf die Sekundärwicklung geometrisch addieren.The reactive components of the inductor current and capacitor current resulting ampere turns in the transformer add up algebraically. Your sum is constant due to the circuit according to the invention. The ampere turns of the active components the two currents, on the other hand, which are always the same size, cancel each other out. So, since constant ampere-turns are impressed on the transformer, one can Apply ampere turns proportional to the load current on the same transformer, and the two parts will be geometrical in their effect on the secondary winding add.
Wenn die Blindwiderstände von Drossel und Kondensator gleich groß gemacht werden, verschwinden praktisch die Erwärmungseinflüsse der Erregerwicklung und des Erregerzubehörs auf die Größe der Spannung.When the reactance of the choke and capacitor is the same are made, the heating effects of the excitation winding practically disappear and exciter accessories to the size of the voltage.
