Abstract

Ovaj diplomski rad bavi se određivanjem vanjskih karakteristika sinkronih hidroge neratora. Kao testni primjeru uzeti su generatori HE M. Blato i HE Lešce. Generatori su modelirani u Motor-CAD-u, a Motor-CAD-om se upravlja preko MATLAB-a. U radu se određuju V-krivulje i krivulje regulacije prvo metodom simulacije, a zatim metodom aproksimacije toka te se usporeduju rezultati. Metoda aproksimacije ulančenog toka se koristi i za određivanje granica konstantne uzbude, granice statičke stabilnosti i granica konstantnog momenta turbine na pogonskoj karti. Rezultati pokazuju poklapanje V-krivulja dobivenih simulacijom i aproksimacijom, osim u slucajevima niske radne snage i visoke struje uzbude.

Abstract (english)

This master thesis deals with the determination of external characteristics of synchronous hydrogenerators. The generators of HE M. Blato and HE Lešce were taken ´
as a test example. The generators are modeled in Motor-CAD while Motor-CAD is
controled via MATLAB. In this thesis, the V curves and control curves are determined first by using the simulation method and then by using the method of flux linkage
approximation method. The resulst of both method are compared. The flux linkage
approximation method is also used for determining the constant excitation curves, the
stability limits, and the constant torque curves in a PQ-chart. The results show that the
only diference between the simulation and the approximation method apear if the field
current is very high or the active power is very low.
