Techno-economic analysis of the measures for power losses reduction in the distribution network

U ovom diplomskom radu opisana je distributivna mreža, njezine osnovne strukture i dijelovi kao što su distributivni transformatori, nadzemni vodovi i kabeli te potrošači. Cilj diplomskog rada je utvrditi koja metoda nudi najbolje rješenje za smanjenje gubitaka distributivne mreže pomoću tehno-ekonomske analize. Metode obrađene u radu su: dodavanje distribuirane proizvodnje, kompenzacija jalove snage, povećanje presjeka vodova, prelazak na višu naponsku razinu te metoda upravljanja potrošnjom koja još nije u upotrebi, ali ima veliki potencijal u smanjenju gubitaka. Sve metode osim upravljanja potrošnjom simulirane su u programskom paketu DIgSILENT PowerFactory te su sve metode ostvarile određeno smanjenje gubitaka. Za svaku metodu određen je period povrata investicije kako bi se odredila najisplativija metoda.This thesis describes the distribution network, its basic structures, and parts such as distribution transformers, overhead lines, cables, and consumers. The aim of the thesis is to determine which method offers the best solution for reducing the losses of distribution networks using techno-economic analysis. The methods covered in this paper are addition of distributed generation, reactive power compensation, increase the cross section of the lines, transition to a higher voltage level and energy management method that is not yet in use, but has great potential in loss reduction. All methods except energy management were simulated in the DIgSILENT PowerFactory software package and all methods achieved a certain loss reduction. For each method, a payback period is determined to determine the most cost-effective method
