| Abstract | U radu je prikazana podijela stabilnosti i opisane kutna i naponska stabilnost. Prikazana
je analiza u kojoj možemo vidjeti utjecaj različitih metoda na stabilnost sustava. Analiza je
rađena na mreži koja je za ovu analizu imala postavljeno nestabilno stanje. Nestabilno stanje
sustava je bilo potrebno određenim metodama vratiti u stabilno stanje u pogledu prijelazne
stabilnosti. Metode koje su prikazane u radu su pomno odabrane kako bi imale utjecaj na
prikazanom sustavu i na prijelaznoj stabilnosti. Analize su rađene u programskom sučelju
DigSILENT, a korištene su modalna analiza i analiza participacijskih faktora kako bi se
prikazale svojstvene vrijednosti sustava, kojima je prikazana stabilnost sustava.
Drugi dio rada se odnosi na metodu koja se temelji na dodavanju FACTS uređaja u
sustav. Njihovo djelovanje temelji se na kontroli jalove i djelatne snage a njihova glavna podjela
je podjeljena na serijske, poprečne i kombinirane uređaje. Za prikaz utjecaja FACTS uređaja
koristili smo SVS uređaje a dobiveni rezultati su pokazali da FACTS uređaji mogu pridonjeti
poboljšanju stabilnosti elektroenergetskog sustava. |

| Parallel abstract (English) | In this paper are described angled and voltage stability. Analisis, in which we can see influece of
different methods on stability of the system, is presented. Analisis was done on the network
which had unstable behavior. It was necessary, with certain methods, this behavior bring back in
stable behavior, in sense of transient stability. Methods presented in paper were chosen carefully,
so they could have influence on the system and transfer stability. Analisis was done in
programming interface called DigSILENT, and used methods were modal analisis and analisis
of participation factors so they could present eigenvalues of system. Eigenvalues of system
present its stability.
Further, method based on FACTS devices is described. Their function is based on active
and reactive power, and they are divided on serial, crossed and combined devices. SVS devices
were used for presenting influence of FACTS devices. Results showed that FACTS devices can
bring to improving stability of electroenergetic system. |
