Abstract

Analiza sigurnosti elektroenergetskih mreža jedan je od najvažnijih proračuna pri vođenju EES-a. U radu je objašnjena teorijska pozadina dinamičke i statičke analize sigurnosti sustava. Unutar tih poglavlja predstavljen je niz indeksa koji omogućuju bržu detekciju opasnih kvarova i njihovo rangiranje. U nastavku je opisan utjecaj suvremenih promjena u sustavu, kao što su HVDC vodovi i restrukturiranje EES-a, na sigurnost. Nadalje, u osmom je poglavlju opisan postupak statičke i dinamičke analize sigurnosti pomoću programskog paketa PSS/E te su iste rađene na primjeru IEEE mreže s 14 sabirnica. Konačno, u zaključku su dobiveni rezultati komentirani te su predloženi idući koraci za nastavak istraživanja.

Abstract (english)

Power system security assessment is one of the most important calculations for running the power system. This paper explains the theoretical background of the dynamic and static security assessment. Within these chapters a series of indices that allow rapid detection of dangerous faults and their ranking is explained. The following chapters describe the impact of contemporary changes in the system, such as HVDC lines and deregulation of the power system, to the security assessment. Furthermore, in the eight chapter, the procedure for static and dynamic security analysis using the PSS/E is explained and presented on the IEEE 14 – bus test network. Finally, in conclusion, the obtained results are discussed and the next steps for the research are proposed.
