Description

  

  Dispositif permettant<B>de</B> maintenir automatiquement la même tension<B>à</B> deux       centrales.à    courant alternatif couplées en parallèle au moyen d'un feeder.    Lorsque deux usines génératrices de courant  alternatif situées<B>à</B>     nue    certaine distance l'une  de l'autre doivent être couplées en parallèle,  il se présente certaines difficultés pour réaliser  l'échange de puissance sans altérer la cons  tance de la tension aux deux centrales. Ces  difficultés tiennent<B>à</B> la grandeur<B>de</B> l'impé  dance du feeder qui relie les deux centrales.  



  Pour permettre de maintenir automatique  ment la même tension<B>à</B> deux semblables  centrales<B>à</B> courant alternatif, couplées en  parallèle au moyen d'un feeder et entre les  quelles on se     propoqe    d'échanger une puissance       wattée    et     déwattée    suivant un taux variable  <B>à</B> volonté,     une    génératrice série<B>à</B> collecteur  est, suivant l'invention, intercalée en série  dans le feeder de couplage et compense auto  matiquement l'impédance de ce feeder.  



  On sait qu'une telle machine, entraînée<B>à</B>  vitesse constante, possède une impédance cons  tante. En dimensionnant convenablement     ses     enroulements et en donnant aux balais     nu     décalage approprié, on petit faire en sorte    que cette impédance soit égale en valeur ab  solue, et de sens opposé,     it    l'impédance a       compeii-wr.    Quelle     que    soit l'intensité du cou  rant dans le feeder, la machine compensera  alors exactement la chute     olimique    et     indue-          tive    de ce feeder, et tout     se    passera comme  si les deux usines étaient en voisinage immédiat.  



  La machine se réalisera par exemple de  la manière suivante:  Chaque phase du     feeder    traversera     nue     des phases de l'enroulement du stator, le  rotor sera excité par le secondaire d'un     traits-          formateur    dont le primaire sera en série avec  le feeder, on plus simplement par     nu    enroule  ment auxiliaire spécial, de dimensions appro  priées et disposé convenablement sur le stator.  



  Pour du courant polyphasé. on aura avan  tage<B>à</B> adopter     nue    vitesse voisine (le la vitesse  synchrone.  



  Pour     dit    courant monophasé,     011    pourra       eniployer        une    génératrice série à collecteur       d'qui    type quelconque, par exemple,     une    généra  trice<B>à</B> répulsion     eoiiipeii.,,,c-e        Latour.         La machine petit être entraînée de<B> </B> façon  quelconque; on l'entraînera par exemple au  moyen d'un moteur indépendant, ou bien en  la plaçant en bout d'arbre d'un alternateur  d'une des deux centrales<B>à</B> coupler.



  Device allowing <B> </B> to automatically maintain the same voltage <B> at </B> two AC power stations coupled in parallel by means of a feeder. When two alternating current generating plants located <B> at </B> a certain distance from each other have to be coupled in parallel, certain difficulties arise in achieving the exchange of power without altering the consistency of the power. the voltage at the two plants. These difficulties are due <B> to </B> the magnitude of the <B> </B> impedance of the feeder which connects the two plants.



  To make it possible to automatically maintain the same voltage <B> at </B> two similar alternating current <B> </B> power stations, coupled in parallel by means of a feeder and between which it is proposed to exchange a watted and dewatted power according to a variable rate <B> at </B> will, a generator series <B> with </B> collector is, according to the invention, inserted in series in the coupling feeder and automatically compensates the impedance of this feeder.



  It is known that such a machine, driven <B> at </B> constant speed, has a constant impedance. By suitably sizing its windings and by giving the brushes an appropriate offset, it is possible to ensure that this impedance is equal in value ab solute, and in the opposite direction, the impedance has compeii-wr. Whatever the intensity of the current in the feeder, the machine will then compensate exactly for the olimic and undue drop in this feeder, and everything will happen as if the two factories were in the immediate vicinity.



  For example, the machine will be implemented as follows: Each phase of the feeder will pass through the phases of the stator winding, the rotor will be excited by the secondary of a trainer whose primary will be in series with the feeder, we more simply by means of a special auxiliary winding, of suitable dimensions and suitably arranged on the stator.



  For polyphase current. we will have the advantage <B> to </B> adopting a neighboring speed (the synchronous speed.



  For said single-phase current, 011 may employ a series collector generator of any type, for example, a <B> with </B> repulsion eoiiipeii. ,,, c-e Latour generator. The machine can be driven in any <B> </B> way; it will be driven for example by means of an independent motor, or by placing it at the end of the shaft of an alternator of one of the two power plants <B> to </B> to be coupled.
