Abstract

U diplomskom radu razrađene su tri najpoznatije metodologije određivanja nadomjesnih vanjskih modela za vanjske mreže, WARD, REI i ULF. Budući da je primjena vanjskih nadomjesnih modela najčešća u modeliranju ekvivalenta vanjske mreže za potrebe proračuna tokova snaga i analizu sigurnosti, ovaj diplomski rad se bavi upravo određivanjem takvih vanjskih ekvivalenata.
Proračunom WARD ekvivalenta, temelja praktičnog dijela rada, na dijelu elektroenergetskog sustava Republike Hrvatske (16 čvorišta), dobiveni su očekivani rezultati. PSS-om je dokazano da se mreža može ekvivalentirati na ovakav način jer su kao konačna potvrda ispravnosti proračuna jednaki naponi na sabirnicama po iznosu i kutu u odnosu na neekvivalentiranu mrežu.

Abstract (english)

The thesis analyzed three leading methods for determining replacement external models for external networks WARD, REI and ULF. Since the application of external replacement models is most common in modeling the equivalent of an external network for load flow calculation and safety analysis, this thesis precisely deals with determining such external equivalents.
By calculating the WARD equivalent which is the basis of the practical part of this thesis, expected results were obtained on one segment of the Croatian power system (16 intersections). PSS proves that the network can equivalented in that way because the bus voltage is equal in the amount and angle with respect to the nonequivalent network, which is the final confirmation of the validity of the calculation.
