Abstract
Treperenje napona (flikeri) predstavljaju oscilacije vrijednosti napona koje se ponavljaju, a izazivaju vidom zamjetljivo kolebanje svjetlosne gustoće. Uzroci treperenja napona su velike i nagle promjene opterećenja koje su uzrokovane radom velikih potrošača, koji troše velike i promjenjive količine snage iz mreže. Elektrolučna peć je glavni predstavnik takve grupe potrošača. Zbog toga je nužno kompenzirati jalovu snagu na odgovarajući način kako bi se smanjio negativni povratni utjecaj na mrežu. Korištenjem dostupnih matematičkih modela elektrolučne peći moguće je odabrati odgovarajući oblik dinamičke kompenzacije te tako pozitivno djelovati na parametre kvalitete električne energije. Iako je diplomskim zadatkom bilo zadano provjeriti da li elektrolučna peć u pogonu Livnice (Bačka Topola) zadovoljava parametre kvalitete električne energije, u diplomskom radu dan je pregled matematičkih modela koji se koriste prilikom modeliranja elektrolučne peći te teorijski opis uređaja za kompenzaciju jalove snage.
Abstract (english)
Voltage flicker is a visible change in brightness of a lamp due to rapid fluctuations in the voltage of the power supply. The causes of voltage flicker are large and sudden load changes that are caused by the work of large customers, who spend large and variable amounts of power from the grid. Electric arc furnace is the main representative of these groups of consumers. Therefore, it is necessary to compensate the reactive power in an appropriate manner to reduce the negative feedback effect on the network. By using the available mathematical models of electric arc furnace it is possible to select the appropriate form of dynamic compensation and thus have a positive effect on the quality parameters of electricity. Although the graduate task was to check whether the default electric arc furnace in operation Foundries (Backa Topola) meets the parameters of power quality, the thesis gives an overview of mathematical models that are used for modeling the electric arc furnace and theoretical description of devices for reactive power compensation.
