Description
Einrichtung zur mehrpunktigen Überlagerung von Starkstromnetzen aus einer gemeinsamen Sendestation mit Strömen netzfremder Frequenz Es ist bekannt (Abb. i), Starkstromnetze aus einer besonderen zu der \Tetzstromquelle Qt4, parallel liegenden Überlagerungsstromquelle mit Strömen netzfremder Frequenz zu überlagern, beispielsweise über einen durch einen Cberlagerungsgenerator ä gespeisten Cberlagerungstransformator t, vor «-elchen ein Schwingungskreis, bestehend aus Sperrkapazität c, gegebenenfalls mit einer auf die Netzfrequenz abgestimmten Parallelsperrdrossel D und einer regelbaren Induktanz d, vorgeschaltet ist, mittels welcher der Schwingungskreis c, D auf die überlagerte Frequenz abgestimmt wird.Device for multi-point superposition of power networks a common transmitting station with currents of non-network frequency It is known (Fig. i), high-voltage networks from a special one parallel to the mains current source Qt4 Overlay current source with currents of non-network frequency to superimpose, for example via a superposition transformer fed by a superposition generator t, before «-elchen an oscillation circuit, consisting of blocking capacitance c, if necessary with a parallel blocking reactor D matched to the mains frequency and an adjustable one Inductance d, is connected upstream, by means of which the oscillation circuit c, D to the superimposed frequency is tuned.
Um mit dieser bekannten Anordnung auch ausgedehntere Netze, insbesondere solche mit mehreren 1Vetzspeisepunkten, z. B. Umspannwerken mit getrennten oder bloß über In.duktanzen gekoppelten Sammelschienensystemen, überlagern zu können, wird man vorteilhaft nicht nur einen, sondern mehrere Überlagerungspunkte benutzen, z. B. in jedem der U mspannwerke.To with this known arrangement also more extensive networks, in particular those with several 1Vetzspeispunkten, z. B. substations with separate or to be able to superimpose busbar systems merely coupled via inductances, it is advantageous to use not just one but several overlay points, z. B. in each of the U mspannwerke.
Es wäre zwar naheliegend, aber unrichtig, hierzu ein Verbindungskabel zu legen, von welchem die einzelnen Überlagerungstransfortnatoren primärseitig gespeist werden; diese Anordnung hat den Mangel, daß an jedem Punkte gesonderte Schwingungskreise angeordnet und gesondert geregelt werden müssen, was auf sehr erhebliche Schwierigkeiten stoßen würde. Erfindungsgemäß werden die Hilfsleitungen derart angeschlossen, daß nur eine regelbare Induktanz d in der Station A vorzusehen ist, durch die auf die zu überlagernde Frequenz eingeregelt wird. Bei dieser Schaltung liegt zwischen jedem Hilfskabelleiter und einer Netzphase ein Sperrkreis, so daß das Hilfskabel keinen Netzstrom führt. Die Abb. 2 zeigt die erfindungsgemäße Schaltung für ein Drehstromnetz mit den Umspannwerken A, B, C, wobei in A die Überlagerungsstromquelle- vorgesehen ist; die Hilfsleitungen a, b, c sind hier an den Punkten zwischen Sperrkreis und Regelinduktanz angeschlossen.It would be obvious, but incorrect, to lay a connecting cable for this purpose, from which the individual superimposition transformers are fed on the primary side; this arrangement has the disadvantage that separate oscillation circles have to be arranged and regulated separately at each point, which would encounter very considerable difficulties. According to the invention, the auxiliary lines are connected in such a way that only a controllable inductance d is to be provided in station A, by means of which the frequency to be superimposed is regulated. In this circuit there is a blocking circuit between each auxiliary cable conductor and a mains phase so that the auxiliary cable does not carry mains current. Fig. 2 shows the circuit according to the invention for a three-phase network with the substations A, B, C, with the superposition current source is provided in A; the auxiliary lines a, b, c are connected here to the points between the blocking circuit and the control inductance.
Die Abb. 3 zeigt die analoge Schaltung für ein Zweiphasen-Dreileitersystem, die Abb.4 für ein Einphasensystem.Fig. 3 shows the analog circuit for a two-phase three-wire system, Fig.4 for a single-phase system.
Es ist empfehlenswert (Abb.5), an den Überlagerungspunkten vor den Sperrkreisen dreiphasige Schalter S einzubauen, welche zweckmäßig von Resonanzrelais r, s bedient werden, die an zwei beliebige Leiter des Hilfskabels a, b, c angeschlossen werden können, man kann derart bei Beginn der Impulsgabe die Schalter mit den r-Relais einschalten, z. B. mit der tiefsten Frequenz des verwendeten Frequenzbandes, und sie mittels der s-Relais nach beendeter Impulsgabe, beispielsweise mit der höchsten Frequenz des Bandes, wieder abschalten, wobei die Kondensatoren c über Widerstände w entladen werden; dies hat den Vorteil, daß die Sperrkreise und das Hilfskabel nur während der Impulsgabe an der Netzspannung liegen.It is recommended (Fig. 5) to install three-phase switches S at the superimposition points in front of the trap circuits, which are conveniently operated by resonance relays r, s, which can be connected to any two conductors of the auxiliary cable a, b, c At the beginning of the impulse, turn on the switch with the r-relay, e.g. B. with the lowest frequency of the frequency band used, and switch them off again by means of the s-relay after the end of the pulse transmission, for example with the highest frequency of the band, the capacitors c being discharged via resistors w; this has the advantage that the blocking circuits and the auxiliary cable are only connected to the mains voltage during the impulse generation.
