Application of contingency analysis in power system control

Cilj ovog rad je upoznavanje s još jednim od proračuna bitnih za ispravno vođenje i dimenzioniranje EES-a. Kako svaka od metoda proračuna zahtjeva određeno modeliranje elementata sustava, tako i ova. Zbog toga na samom početku rada objašnjeno je upravo to. Jedan od bitnijih kvarova su kaskadni ispadi, koji mogu dovesti do velikih posljedica po sustav, jedna od njih je potpuni raspad sustava (eng. blackout). Konačno dolazi na red glavna tema ovog rada, odnosno analize sigurnosti n-1. Ukratko je objašnjeno što je to, koje postoje vrste i posljedice raznih parametara na analizu. Uz objašnjenje teorije same analize sigurnosti N-1 za vođenje EES-a, objašnjeno je korištenje programskog alata PSS/E, odnosno eng. Power System Simulator for Engineers. Prikazani su rezultati proračuna u različitim oblicima, te različiti utjecaji ispada na sustav.The main goal of this thesis is to explain one of the most important analysis in power system analysis, which is important for power system control. Like every other method, we need to start with power system elements modeling. Cascade outages is failure which is important for this problem. Cascade outages can have really big impact on power system, the biggest consequence is completely electrical power blackout. Finally, the main problem of this thesis, contingency analysis. The thesis gives theoretical explanation of analysis. How it is divided into two analyzes, also consequences of some important parameters on analysis. With all the explained theory, this thesis also shows how to properly use planning tool called Power System Simulator for Engineering, PSS/E. Different types of results are shown in this thesis, also consequences that some outages can have on system
