 mit   der Stromapule a für   den Regler des zweiten Generators, der   Stromtransformator     tt   des zweiten Generators mit der Stromspule h3 für den Regler des dritten Generators und der Stromtransformator   Is   des dritten Generators mit der Stromspule   Àt   des ersten Generators verbunden. 



   In der Zeichnung ist der Anschluss des Strom-und Spannungswandlers eines jeden Generators an dessen Klemmen so dargestellt, dass bei reinem wattlosen Strom die von der Strom-und Spannungsspule des Schnellreglers erzeugten magnetischen Felder annähernd in Phase sind. 



  Man kann natürlich, je nachdem man die Regelung mehr durch den wattlosen bzw. durch den Wattstrom beeinflussen will, durch geeignete Wahl des Anschlusses der Transformatoren an andere Phasen des Generators oder durch die an sich bekannte Einschaltung von Selbstinduktion oder Kapazität in die Sekundärwicklung dieser Transformatoren oder durch beide Mittel, die Phase dieser Felder gegeneinander entsprechend verschieben. 



   Wenn nun einer der Generatoren (Generatorgruppen) abgeschaltet werden soll, so ist durch eine Umschaltvorrichtung auch die   Sekundärwicklung   des Stromtransformators bzw. der   Abzweigwide, rstand   des in der zyklischen Reibe dem abzuschaltenden Generator (Generator-   gruppe)   vorhergehenden Generators mit dem Regelungsorgan des in der zyklischen Reihe dem   a. b1. uschaltenden   Generator   (Generatorgruppe) nächstfolgenden   Generators (Generatorgruppe) zu verbinden.

   Wenn also beispielsweise in der Figur der Generator 92 mit dem zugehörigen Regelungssystem vom Netz c abgeschaltet wird, so wird die Sekundärwicklung des zum   Generator g   gehörigen Transformators t1 mit der Wicklung h3 des zum Generator   gg gehörigen Reglers   ver-   bunden.   Arbeitet schliesslich nur ein generator (Generatorgruppe) auf das Netz, so wird die
Sekundärwicklung des zugehörigen   Stromtra. nsfotmators   an die Stromspule des diesen Generator regelnden   SchneUreglers angeschlossen.   



   PATENT ANSPRÜCHE :
1. Einrichtung zum selbsttätigen Regeln von mehr als zwei parallel arbeitenden, unabhängig voneinander erregten Generatoren oder Generatorgruppen auf proportionale Belastungsverteilung, dadurch gekennzeichnet, dass das   Regehmgsorgan   eines jeden Generators (Generatorgruppe) durch die Stromstärke des in der Reihe der Generatoren in zyklischer Vertauschung voran- gehenden Generators (Generatorgruppe) in dem Sinne beeinflusst wird. dass mit zunehmender bzw. abnehmender Belastung eines   Generators (Generatorgruppe)   die Erregerspannung des in der Reihe nächstfolgenden   (Generators (Generatorgruppe) erhöht bzw. erniedrigt wird, zum  
Zwecke, die Änderung des Belastungsstromes eines generators auf die Gesamtzahl der Generatoren zu übertragen.

 connected to the current coil a for the regulator of the second generator, the current transformer tt of the second generator with the current coil h3 for the regulator of the third generator and the current transformer Is of the third generator with the current coil Àt of the first generator.



   In the drawing, the connection of the current and voltage converter of each generator to its terminals is shown in such a way that with pure wattless current the magnetic fields generated by the current and voltage coil of the high-speed regulator are approximately in phase.



  You can of course, depending on whether you want to influence the regulation more by the wattless or by the watt current, by a suitable choice of the connection of the transformers to other phases of the generator or by the known inclusion of self-induction or capacitance in the secondary winding of these transformers or by both means, shift the phase of these fields against each other accordingly.



   If one of the generators (generator groups) is to be switched off, the secondary winding of the current transformer or the branch circuit is also switched over by means of a switching device Row the a. b1. switching generator (generator group) to connect the next generator (generator group).

   If, for example, in the figure, the generator 92 with the associated control system is switched off from the network c, the secondary winding of the transformer t1 associated with the generator g is connected to the winding h3 of the regulator associated with the generator gg. If ultimately only one generator (generator group) is working on the network, the
Secondary winding of the associated Stromtra. nsfotmators connected to the current coil of the speed regulator regulating this generator.



   PATENT CLAIMS:
1. Device for the automatic control of more than two parallel working, independently excited generators or generator groups on proportional load distribution, characterized in that the Regehmgsorgan of each generator (generator group) by the current strength of the preceding in the series of generators in cyclical exchange Generators (generator group) in the sense is influenced. that with increasing or decreasing load of a generator (generator group) the excitation voltage of the next in the series (generator (generator group) is increased or decreased, for
Purpose of transferring the change in the load current of a generator to the total number of generators.
