Abstract

Problematika proračuna kratkog spoja je poznata, ali se i dalje susrećemo s kompliciranim problemima. U ovom radu je opisan način modeliranja mreže metodom redukcije, tako da se dobije ekvivalent vanjske mreže koji vjerno predstavlja prilike u mreži. Na takav način se mogu računati struje kratkog spoja, ručno ili u nekom programskom alatu. Postupci proračuna korišteni u ovom radu su otprije poznati, ali je metoda modificirana tako da se u konačnici dobiju ispravni rezultati. Naveden je i primjer neispravnog korištenja metode. Svi rezultati i proračuni su rađeni koristeći programske pakete PSS i Matlab.

Abstract (english)

Fault analysis issues are well known, but new problems emerge every day. This thesis deals with the network reduction modelling method used to produce an outer network equivalent imitating real network operation. With this method, fault current can be calculated either by hand or using a programming tool. Calculation procedures used in this thesis are common, but the method itself is modified in order to produce correct end results. An example of incorrect use of the method is described as well. All results and calculations are made using PSS and Matlab programming tools.
