Description

Zur selbsttätigen Regelung von Gleichstromgeneratoren, z. B. Leonardgeneratoren, ist folgende Anordnung bekannt: Die Spannung des Generators wird verglichen mit dem Spannungsabfall an einem Widerstand in einem Hilfsstromkreis, dessen Strom durch einen Sollwerteinsteller regelbar ist. Die Differenzspannung wird zur Erregung einer Verstärkermaschine benutzt. Diese speist die Erregerwicklung des Generators. Außerdem wird zweckmäßigerweise zur Unterdrückung von Pendelungen noch der erste Differentialquotient der geregelten Generatorspannung zur Mitbeeinflussung der Erregermaschine herangezogen. Dies geschah bei bekannten Anordnungen durch den Einbau von Transformatoren oder Kondensatoren. Solche Lösungen sind jedoch umständlich und kostspielig.For the automatic control of direct current generators, e.g. B. Leonard generators, the following arrangement is known: The voltage of the generator is compared with the voltage drop across a resistor in an auxiliary circuit, the current through which a setpoint adjuster can be regulated. The differential voltage is used to excite a Amplifier machine used. This feeds the generator's excitation winding. aside from that The first differential quotient is expediently used to suppress oscillations the regulated generator voltage is used to influence the exciter. In known arrangements, this was done by installing transformers or Capacitors. However, such solutions are cumbersome and costly.

Eine wesentlich einfachere Lösung besteht gemäß der Erfindung darin, daß von einem an der Ankerspannung der Erregermaschine liegenden und einem im Erregerstromkreis des geregelten Gleichstromgenerators liegenden Widerstand eine der Differenz aus der Klemmenspannung der Erregermaschine und dem Spannungsabfall im Erregerstromkreis des geregelten Gleichstromgenerators proportionale Hilfsspannung abgegriffen und an eine Hilfserregerwicklung der Erregermaschine gelegt wird. Spannungsteiler und Widerstände sind einfache, billige Geräte. Die Hilfsspannung läßt sich durch geeignete Wahl der Anzapfungen einfach und genau einstellen.According to the invention, a much simpler solution consists in that of one lying on the armature voltage of the exciter and one in the excitation circuit of the regulated DC generator lying resistance one of the difference the terminal voltage of the exciter and the voltage drop in the exciter circuit the regulated DC generator tapped proportional auxiliary voltage and is applied to an auxiliary excitation winding of the excitation machine. Voltage divider and Resistors are simple, cheap devices. The auxiliary voltage can be adjusted by suitable Set the choice of taps easily and precisely.

Im folgenden ist die Erfindung an Hand der Zeichnung erläutert.The invention is explained below with reference to the drawing.

Diese zeigt das Schaltbild eines Ausführungsbeispiels einer Regeleinrichtung nach der Erfindung. I ist ein Gleichstromgenerator, der die Stromschienen ± speist. Seine Erregerwicklung 2 wird gespeist von einer regelnden Verstärkermaschine 3, deren Erregerwicklung 4 an die Klemmenspannung der Maschine I und an einen Widerstand 5 gelegt ist. Der Widerstand 5 wird von einem mittels des Sollwerteinstellers 6 einstellbaren Strom durchflossen. Der an ihm auftretende Spannungsabfall ist der Klemmenspannung der Maschine I entgegengerichtet, so daß die Erregerwicklung 4 die Differenz zwischen der Generatorspannung und der einstellbaren Vergleichsspannung zugeführt erhält. An der Ankerspannung der Erregermaschine liegt ein Spannungsteiler 7 und im Erregerstrom des geregelten Gleichstromgenerators ein Widerstand 8. Von diesen beiden Widerständen ist eine der Differenz aus der Klemmenspannung der Erregermaschine und dem Spannungsabfall im Erregerstromkreis des geregelten Gleichstromgenerators proportionale Hilfsspannung abgegriffen und an eine Hilfserregerwicklung 9 der Erregermaschine 3 gelegt. Diese wird somit durch die erwähnte Spannungsdifferenz mitbeeinflußt, so daß etwaige Pendelungen, die sonst bei der Regelung auftreten könnten, unterdrückt werden.This shows the circuit diagram of an exemplary embodiment of a control device according to the invention. I is a DC generator that feeds the ± busbars. Its excitation winding 2 is fed by a regulating amplifier machine 3, their excitation winding 4 to the terminal voltage of the machine I and to a resistor 5 is placed. The resistor 5 is set by a means of the setpoint adjuster 6 adjustable current flowing through it. The voltage drop occurring across it is the Terminal voltage of the machine I counteracted so that the excitation winding 4 the Difference between the generator voltage and the adjustable reference voltage receives fed. A voltage divider is connected to the armature voltage of the exciter 7 and a resistor 8 in the excitation current of the regulated DC generator of these two resistances is one of the difference between the terminal voltage of the exciter and the voltage drop in the excitation circuit of the regulated DC generator proportional auxiliary voltage tapped and to an auxiliary excitation winding 9 of the exciter 3 laid. This is thus also influenced by the voltage difference mentioned, so that any oscillations that might otherwise occur during the regulation are suppressed will.
