Abstract	Zadatak ovog rada bio je prikazom P-V krivulja i Q-V krivulja odrediti stabilnost sustava, odnosno granice stabilnosti sustava. Kroz analiziranje regulacije napona, pobliže je opisan princip kompenzacije jalove snage u mreži. Definirana je stabilnost sustava, te je prikazana podjela stabilnosti ovisno o promatranoj veličini. Naponska je stabilnost kao tema ovog rada bila temeljito obrađena. Kroz teoretske primjere je prikazano definiranje naponske stabilnosti, odnosno nestabilnosti sustava. Nakon toga su na praktičnom primjeru 39 sabirničke mreže određivane granice stabilnosti sustava. Za analizu je korišten program DIgSILENT PowerFactory. Prvobitno je određena granica naponske stabilnosti u sustavu bez ikakve kompenzacije jalove snage. Nakon toga se kondenzatorskom baterijom na sabirnici s kritičnim naponom jalova snaga kompenzirala. Pri tome je promatran utjecaj kompenzacije na P-V i Q-V krivulje. Može se zaključiti da kompenzacijom jalove snage sustav postaje stabilniji.
Abstract (english)	The goal of this thesis was to determine system stability i.e. the limit of voltage stability by showing its P-V and Q-V curves. Trough the analysis of voltage control, compensation of reactive power is closely described. System stability is defined, and its classification is given depending on the variable that is being monitored. Voltage stability was thoroughly analyzed because its the main topic of this thesis. Trough some theoretical examples voltage stability definition was given i.e. voltage instability. DIgSILENT PowerFactory program was used for the analysis. Originally voltage stability limit was determined without any kind of reactive power compensation in the system. After that a capacitor bank was connected to the bus that showed the critical voltage. The influence of capacitor banks on the P-V and Q-V curves was monitored. It can be concluded that the system becomes more stable by compensating the reactive power.
