20.500.12556/DKUM-13421 OPTIMALNI REŽIM OBRATOVANJA USMERNIŠKIH SKUPIN V TALUM KIDRIČEVO OPTIMAL OPERATING REGIME OF RECTIFIER GROUPS IN TALUM KIDRIČEVO V diplomskem delu je izdelan optimizacijski program za izračun optimalnih izgub usmerniških skupin. Optimizacijski program je izveden v programu MatLab, in sicer na podlagi enačb izgub, pridobljenih s karakteristikami izgub posameznih usmerniških skupin. Opisano je tudi delovanje petih usmerniških skupin, ki s pretvarjanjem izmenične energije v enosmerno so-omogočajo proizvodnjo elektroliznega aluminija. Z različnimi kombinacijami obremenitev usmerniških skupin se izgube le teh spreminjajo. Posledično je možno prihraniti pri plačilu električne energije, zato je izdelan še izračun letnega finančnega prihranka. In this diploma work the optimization program for calculating the optimal losses of rectifier groups was developed. The optimization program was written in the program MatLab, based on the equations of losses, which were gained by characteristics of losses of individual rectifier groups. The working of five rectifier groups, which co-facilitate the production of electrolytic aluminium by transforming alternating into direct energy was also described. With different load combinations of rectifier groups their losses changed. Consequently, savings in the payment of electric energy were possible and because of this, the last focus of this diploma work was the calculation of annual financial saving. elektroenergetske naprave proizvodnja elektroliznega aluminija usmerniška skupina optimalno obratovanje električne izgube in izkoristki electric power equipment production of electrolytic aluminium rectifier group optimal operation power losses and efficiencies true true false [D.
