Abstract
29,178. Marks, E. C. R., [Akt.-Ges. Brown, Boveri, et Cie]. Dec. 28. Equalizing load on generator; systems of charging and discharging galvanic batteries. - The load on the generator of an electric hauling or rolling-mill plant &c., operating on the Ward-Leonard principle, is equalized by connecting a buffer source in parallel with the generator, and controlling the voltage of the generator or buffer source in accordance with the voltage and current output of the generator or with the voltage and current supplied to an electric motor driving this generator. In the arrangement shown in Fig. 1, the buffer source comprises a dynamo-electric machine 1 coupled to a fly-wheel 10 and connected in parallel with a generator 2 supplying the operating-motor 3. A field-winding 4 of the machine 1 and the fieldwinding 5 of the generator 2 are connected in series across the mains 8, and the current in these windings is controlled by a variable resistance 9. The machine 1 is also provided with a field-winding 7, the current in which is varied in accordance with the voltage and current of the generator 2 by means of a differentially compound-wound solenoid 12 and a resistance 11. In a modification, the field-winding 7 is placed on the generator field magnets. In the modification shown in Fig. 2, the buffer source is a battery 14, the number of active cells of which is varied by means of the solenoid 12 and a switch 15. In a modification, the solenoid 12 and switch 15 are replaced by a booster.
