Abstract	Svrha sigurnosnih analiza elektroenergetskog sustava u stacionarnom stanju nalazi se u određivanju elemenata čiji ispadi uzrokuju narušavanje postavljenih ograničenja kao i u procjeni stupnja ozbiljnosti svakog od tih narušenja. Za veće sustave, čak i ako se razmatraju samo jednostruki ispadi i ako se koriste brze metode rješavanja, cjelovita izmjenična analiza svih slučajeva ispada zahtjeva dugotrajan postupak koji za primjenu u realnom vremenu nije prihvatljiv. Stoga se u svrhu oblikovanja liste kritičnih slučajeva ispada koriste brzi i aproksimativni postupci proračuna tokova snaga pomoću kojih se unaprijed u kratkom vremenu predviđaju kritični elementi čiji ispadi uzrokuju preopterećenja ili naponske neprilike, nakon čega se cjelovita izmjenična analiza izvodi samo nad najtežim slučajevima. Oblikovanje liste ispada izvodi se automatski korištenjem metoda rangiranja prema vrijednostima indeksa ozbiljnosti učinka ispada ili korištenjem metoda ukazivanja na kritične elemente pri čemu nije nužno proračunavati vrijednosti indeksa, jer je od značenja samo utvrđivanje postojanja ili nepostojanja narušenja ograničenja. Pri izvođenju algoritama od izuzetnog su značenja matematički postupci rada s rijetko popunjenim matricama te postupci ekvivalentiranja vanjskog dijela sustava čijim korištenjem se cijeli proces ubrzava i sažima skraćujući time ukupno vrijeme izvođenja.
Abstract (english)	The purpose of steady-state power system security analysis is to determine which contingencies cause component limit violations and also severity of any such violations. For large systems, even if only single component contingencies were considered, and even if fast solution methods were employed, full AC analysis of all cases could be prohibitively time consuming especially in real time mode. In order to avoid this computational burden contingency list is formed by approximate load flow solution methods which in contingency selection procedure estimate in advance contingencies more likely to cause limit Violations, following by full AC analysis only for the more severe cases. Contingency selection procedure is automated using ranking methods according to their performance index values or using screening methods which do not necessary need ranking by severity, because the most important issue within these methods is to identify cases which cause limit violations. These methods are enhanced by using sparse matrix techniques and local solution concept involving external equivalents in field of avoiding time consuming routines and reducing whole problem.
