Description

Einrichtung zur unabhängigen Spannungsregelung von durch eigene Synchrongeneratoren gespeisten, über Drosselspulen leitend miteinander verbundenen Netzen. Es sind Einrichtungen zur unabhängigen Spannungsregelung von kleineren, durch eigene Synchrongeneratoren gespeisten Netzen bekannt, welche mit anderen Netzen, insbesondere den Netzen einer großen t berlandanlage mit mehreren Zentralen, zum Zweck des Energieaustausches leitend verbunden sind. Eine solche Einrichtung besteht aus einem in die Verbindungsleitung des kleineren Netzes mit dem Hauptnetz eingeschalteten induktiven Widerstand, welcher die Regelung der Spannung des zu regelnden Netzes an der Felderregung der an dasselbe angeschlossenen Synchronmaschinen unabhängig von den Spannungsverhältnissen der übrigen Netze ermöglicht.Device for independent voltage regulation by own synchronous generators powered networks that are conductively connected to one another via choke coils. There are institutions for independent voltage regulation of smaller ones, using their own synchronous generators powered networks known which with other networks, in particular the networks of a large overland system with several control centers for the purpose of exchanging energy are conductively connected. Such a device consists of one in the connecting line of the smaller network with the main network switched on inductive Resistance, which regulates the voltage of the network to be regulated on the field excitation of the to the same connected synchronous machines regardless of the voltage conditions of the other networks.

Diese Einrichtung besitzt aber einen Nachteil, welcher darin besteht, daß der induktive Widerstand einen großen Spannungsabfall verursacht, wenn das Hauptnetz Energie an das kleinere Netz senden soll. Geht man von der Spannung des Hauptnetzes aus und nimmt an, da ß ein Strom I vom Hauptnetz in das kleinere Netz fließen soll, so ist dies nur möglich, wenn die Spannung des kleineren Netzes sich von ;der des Hauptnetzes um den Betrag I # (,) L unterscheidet, wobei c) L die Induktivität der zwischengeschalteten Drosselspule bedeutet. Besitzt der Strom I eine große induktive Komponente, dann fällt dieser Spannungsabfall annähernd in die Richtung der Spannung selbst, und die Spannung des kleineren Netzes ist dann um den genannten Spannungsabfall kleiner als die Spannung des Hauptnetzes. Die Regelung des Energieflusses erfolgt hierbei natürlich an den Kraftmaschinen der Zentrale selbst.However, this device has a disadvantage, which is that the inductive resistance causes a large voltage drop when the main network To send energy to the smaller network. Assuming the voltage of the main network and assumes that a current I should flow from the main network into the smaller network, this is only possible if the voltage of the smaller network differs from that of the Main network differs by the amount I # (,) L, where c) L is the inductance of the interposed reactor means. If the current I has a large inductive value Component, then this voltage drop falls approximately in the direction of the voltage itself, and the voltage of the smaller network is then around the said voltage drop less than the voltage of the main network. The energy flow is regulated here of course on the power machines of the head office itself.

Den erwähnten Spannungsabfall kann man nun für einen bestimmten Belastungsfall vermeiden, wenn man in die Verbindungsleitung der beiden Zentralen außer der Induktivität auch eine Spannung einschaltet, welche den Spannungsabfall für den gewünschten Belastungswert kompensiert.The voltage drop mentioned can now be used for a specific load case Avoid going into the connecting line of the two central units except for the inductance also switches on a voltage which determines the voltage drop for the desired load value compensated.

Es ist nun Gegenstand der Erfindung eine Einrichtung zur unabhängigen Spannungsregelung von durch eigene Synchrongeneratoren gespeisten, über Drosselspulen leitend miteinander verbundenen Netzen, bei welcher eine zusätzliche Spannung in der in die Verbindungsleitung der Netze eingeschalteten Drosselspule mit Hilfe einer auf den gleichen Eisenkern wirkenden zweiten Wicklung erzeugt wird, welche an Spannung liegt und so bemessen und angeordnet ist, da.ß die von ihr in der Drosselspule induzierte Spannung gerade ausreicht, die durch einen bestimmten Belastungsstrom in der Drosselspule induzierte Spannung zu kompensieren, wobei die Koppelung der beiden Neue derart lose ist, daß die Induktivität der Drosselspule durch das Vorhandensein der zweiten Wicklung nicht wesentlich herabgesetzt wird.It is now the subject of the invention a device for independent Voltage regulation of supplied by own synchronous generators, via choke coils Conductive interconnected networks, in which an additional voltage in the inductor switched on in the connection line of the networks with the help of a acting on the same iron core second winding is generated, which is at tension and is so dimensioned and arranged that the induced by it in the choke coil The voltage is just sufficient by a certain load current in the choke coil to compensate induced voltage, the coupling of the two new such is loose that the inductance of the choke coil due to the presence of the second Winding is not significantly reduced.

Die Erfindung sei an Hand der Zeichnung näher erläutert. In der Abbildung ist in die Verbindungsleitung der beiden Netze N1 und N2 die Drosselspule D gezeichnet, auf deren Eisenkern sich die Erregerspule E befindet. D und E sollen lose gekoppelt sein. Die Spule E liegt an der Netzspannung und ist so bemessen, daß die in Spule D induzierte Spannung gleich und entgegengerichtet ist der Spannung, die ein vom Netz N1 nach N2 fließender Belastungsstrom in der Spule D erzeugt. Dadurch wird der Spannungsabfall für einen bestimmten Energiefluß vom Netz N, nach Netz N2 vermieden.The invention will be explained in more detail with reference to the drawing. In the figure, the choke coil D is drawn in the connecting line of the two networks N1 and N2, on the iron core of which the excitation coil E is located. D and E should be loosely coupled. The coil E is connected to the mains voltage and is dimensioned in such a way that the voltage induced in coil D is the same and opposite to the voltage that a load current flowing from mains N1 to N2 generates in coil D. This avoids the voltage drop for a certain energy flow from network N to network N2.
