In proiectarea generatoarelor sincrone, o importanta semnificativa o are determinarea solenatiei de excitatie la
sarcina nominala. Sursele bibliografice de specialitate [1], [2], indica determinarea acestei marimi pe cale grafica. Valoarea
determinata, in acest mod, nu reprezinta de fiecare data valoarea exacta, depinzand de dibacia proiectantului in
constructia grafica si de corectitudinea constructiilor grafice utilizate. Pentru a elimina acest inconvenient, am realizat un
program de calcul matematic prin intermediul caruia, se determina foarte rapid si corect valoarea solenatiei de excitatie.

Abstract
In the designing of the sinchronous generator, a significant importance is the determining of the excitation
solenation at the nominal load. The technical literature sources indicate the determination of this size with graphics construction. The value determined in this way is not always the exact value, depending on the designer's skill in graphic
designing and the accuracy construction graphics used. To avoid this inconvenience, we developed a mathematical program through which, quickly and accurately, we determine the corect value of the excitation solenation.
