Description
Anordnung zum selbsttätigen Leistungsausgleich zwischen mindestens drei spannungsverschiedenen, frequenzgleichen Wechselstromanlagen. Ge.-enstand der Erfindung ist eine Anordnung zum selbsttätigen Leistungsausgleich zwischen mindestens drei spannungsverschie-,lenen, frequenzgleichen We#:hselstromalilagen, deren jede ein Leitungsnetz besitzt, an welches sowohl E-rzeuger als Verbraucher ati geschlosseil sind.Arrangement for automatic performance equalization between at least three voltage-different, same-frequency alternating current systems. The Invention is an arrangement for automatic power balancing between at least three voltage-different, equal-frequency We #: hselstromalilagen, each of which has a pipeline network to which both producers and consumers are closed are.
Vin mehrere spannungsverschiedene, freq,ienzgleiche Wechselstromanlagen zu kuppeln, hat inan bisher stets die zti kuppelnden Anlagen paarweise über je einen Transforinator inagnetiscli zusammengeschaltet. Durch diese paarweise Zusammenschaltung entsteht aber 1.Vin to couple multiple voltage different freq, ienzgleiche ac systems, has been inan always zti-coupling systems work in pairs, via one Transforinator inagnetiscli. However, this paired interconnection results in 1.
nicht nur eine erhebliche Vermehrung des -Maschinenmaterials, des Raumbedarfs und des Leerlaufverlustes, sondern es wird der selbsttätige Leistungsausgleich zwischen den zusammengeschlossenen Anlagen durch die doppelte Transformation wesentlich erschwert und kann vor allem durch unrichtige E'ingriffe des Bedienungspersonals völlig gestört werden.not only a considerable increase in the machine material, the Space requirements and the idle loss, but it becomes the automatic power compensation between the combined plants due to the double transformation difficult and can be caused mainly by incorrect intervention by the operating personnel be completely disturbed.
Gemäß der Erfinduna, wird der Leistungsausgleich durch magnetische Kupplung sämtlicher auszugleichender Anlagen in einem einzigen Transformator herbeigeführt. Derselbe trägt auf gemeinsamem Eisenkörper für jede Anlage verschiedener Spannung, eine völlig selbständige, vonden anderenWicklungen ellektrisch getrennte Wicklung. Die Windungsel zahlen der 'Wicklungen werden für einen normalen anzunehmenden Leistungsfluß zwischen den einzelnen Anlagen konstruiert und stehen, sofern die -,#7erluste des Transformators vernachlässigt werden. in demselben Verhältnis zueinander, wie die durch den angenommenen Leistungsfluß zwischen den Anlagen an den Klernmen jeder Wicklung hervorgerufenen Spannungen.According to the invention, the power compensation is made by magnetic Coupling of all systems to be compensated brought about in a single transformer. The same carries on a common iron body for each system different tension, a completely independent one electrically from the other windings separate Winding. The diaper numbers of 'windings are to be assumed for a normal one Power flow between the individual systems is constructed and available, provided that the -, # 7 losses of the transformer can be neglected. in the same relationship to each other, like the one through the assumed power flow between the systems at the terminals voltages generated by each winding.
Bei Schwankungen dieser Klemmenspannungen verschiebt sich der Leistungsfluß zwischen den angeschlossenen Anlagen im umgekehrten Verhältnis zu diesen Spannungsschwankungen. Dadurch ergibt sich, daß. sofern eine Anlage durch höhere Belastung in ihrer Klemment;pannung am Transformator absinkt, der Leistungszufluß zu dieser Wicklung sich relativ vergrößert, so daß die Anlage automatisch entlastet wird.If these terminal voltages fluctuate, the power flow shifts between the connected systems in inverse proportion to these voltage fluctuations. It follows that. insofar as a system is subject to higher stress in its clamping voltage sinks at the transformer, the power flow to this winding increases relatively, so that the system is automatically relieved.
In Abb. i sind z. B. fünf spannungsverscliiedene, frequenzgleiche Wechselstronianlagen züisammengeschlossen, von welchen jede einzelne ein Leitungsnetz darstellt, an welches sowohl Erzeuger als Verbraucher angeschlossen sind. Bisher waren zu diesem Ausgleich mindestens vier Transformatoren notwendig wobei außer der dreimal notwendig ,en, cloppelten Transformation auch noch der Nachteil auftrat, daß, sofern ein Transformator ausfiel, der einwandfreie Leistungsausgleich völlig ge- stört war.In Fig. B. five voltage-differentiated, frequency-equal AC systems züisammelte, each of which represents a line network to which both producers and consumers are connected. Up to now, at least four transformers were necessary for this compensation In addition to the three times necessary, clopped transformation, there was also the disadvantage that if a transformer failed, the proper power equalization was completely disturbed.
Die Erfindung stellt nun gleichzeitig # eine Verbesserung in der Anlage derartiger Leitung,snetze dar, welche info4-- des auftretenden Übermäßigen Erdschlußstromes elektrisch voneinander getrennt werden müssen. Bisher wurde diese elektrischeTrennting durch Transformatoren mit denlÜbersetzungsverhältnis i - i herbeigeführt. Die Erfindung bezweckt, (liese Trennstelle, welche einen Energieverlust in der Leitung darstellt, auszunutzen und durch Verwendung der Trennstelle als gleichzeitige Transformatorenstelle den Verlust und Materialaufwand für eine solche Trennstelle belan11-los zu machen. Gemäß der Erfindung wird eine jede solche Trenn- und Transforinierungsstelle durch einen einzigen Transformator gebildet, welcher auf gemeinsamem Eisenkern gleichsinnig wirk-ende, elektrisch getrennte, völlig Z, J-1 selbständige Wicklung trägt. Zwei dieser Wicklungen, welche zur Leitungsauftrennung dienen, besitzen gleiche oder annähern-1 gleiche 11 21 Winflungszahlen. Bei letzterer Anordnung wird die abgehende Leitung eine um einige Prozent größere Windungszahl erhalten, um den Spannungsabfall im Transformator und evtl. auch in der vorhergehenden Leitung auszugleichen. Die übri-"en Wicklungen können eine beliebige Winclungszahl besitzen, welche den verlangten Spannungen entsprechen und gemäß den Angaben in Anspruch i festgelegt sind.The invention now represents at the same time # an improvement in the system of such lines, networks, which must be electrically isolated from each other info4-- the excessive earth fault current that occurs. So far, this electrical separation has been brought about by transformers with the transmission ratio i - i. The aim of the invention is to exploit this separation point, which represents a loss of energy in the line, and to make the loss and material expenditure for such a separation point unrelated by using the separation point as a simultaneous transformer point. According to the invention, each such separation and transformation point becomes Formed by a single transformer, which carries electrically separate, completely Z, J-1 independent windings acting in the same direction on a common iron core. Two of these windings, which are used to separate lines, have the same or approximately the same 11 21 turns Arrangement, the outgoing line will have a few percent larger number of turns in order to compensate for the voltage drop in the transformer and possibly also in the previous line Claim i fe are set.
In -'ibb. 2 ist eine Trennstelle mit gleichzeitiger Transformation auf weitere Spannungen dargestellt. Diese elektrische Trennstelle ist zugleich Leistungsausgleichstelle nach Abb. i, wobei, wie aus der Abbildung ersichtlich, die Anzahl der Wicklungen um eins größer sein muß, als die Anzahl der angeschlossenen spannungsverschiedenen, frequenzgleichen Wechselstromanlagen.In -'ibb. 2 is a separation point with simultaneous transformation shown on further voltages. This electrical separation point is also a power equalization point according to Fig. i, where, as can be seen from the figure, the number of windings must be one greater than the number of connected voltage-different, AC systems with the same frequency.
