Strategy for losses reduction in 35 kV distribution system of Elektroslavonija Osijek

U ovom diplomskom radu objašnjene su vrste gubitaka, što su to tehnički gubici, njihova podjela te faktori o kojima ovise gubici. Objašnjen je nastanak gubitaka u transformatorima i vodovima te načini na koji ih smanjiti. Nakon toga opisani su netehnički gubici te uzrok njihovog nastanka. Navedene su i opisane strategije za smanjenje gubitaka pri čemu su detaljnije opisane strategija optimalnog uklopnog stanja i strategija zamjene transformatora. Opisani su slučajevi u kojima se primjenom navedenih metoda promatraju promjene gubitaka u mreži. Cilj ovog rada je otkriti koja od ove dvije strategije za smanjenje bi bila učinkovitija za 35 kW mrežu Elektroslavonije Osijek.This thesis explains the types of losses, what are tehnical losses, their division and the factors on which losses depend. The origin of losses in transformers and lines is explained so as the ways to reduce them. After that, non-tehnical losses and cause of their occurrence are described. Loss reduction strategies are also described where optimal switching state strategy and transformer replacement strategy are being described in more details. Cases are described in which changes in network losses are observed using the above methods. The goal oft his paper is to find out which of these two reduction strategies would be more efficient for 35kW network of Elektroslavonija Osijek
