Abstract
Radom je prikazana važnost modeliranja elemenata elektroenergetskog sustava za proračuna kratkog spoja prema međunarodnoj normi IEC 60909. Kako bi se pojednostavio proračun struja kratkog spoja, koriste se metoda ekvivalentnog naponskog izvora i metoda simetričnih komponenti koje su ovim radom detaljno prikazane. Rad se osvrće i na izračun maksimalne i minimalne struje kratkog spoja, koje su bitne za dimenzioniranje električne opreme u slučaju maksimalne struje, odnosno odabir zaštitnih uređaja u slučaju minimalne struje kratkog spoja. Nadalje, prikazani su konačni izrazi za proračun impedancija elemenata sustava i njihove pripadne nadomjesne sheme, što omogućava pojednostavljenje proračuna struja kratkog spoja. Isto tako od interesa je poznavanje različitih vrsta struja kratkog spoja, kao što su udarna struja kratkog spoja, rasklopna struja kratkog spoja, početna struja kratkog spoja, itd., te su radom prikazani izrazi kojima dolazimo do njihovih vrijednosti za različite vrste kratkih spojeva.
Abstract (english)
The paper shows the importance of modeling the elements of the power system for short-circuit calculation according to the international standard IEC 60909. In order to simplify the calculation of short-circuit currents, the method of equivalent voltage source at the short-circuit location and the method of symmetrical components are used, which are presented in detail in this paper. The paper also looks at the calculation of the maximum and minimum short-circuit current, which are essential for the sizing of electrical equipment in the case of maximum current and the selection of protective devices in the case of minimum short-circuit current. Furthermore, the final expressions for the calculation of the impedance of the system elements and their corresponding schemes are presented, which enables the simplification of the calculation of short-circuit currents. It is also of interest to know different types of short-circuit currents, such as peak short-circuit current, symmetrical breaking current, initial short-circuit current, etc., so the work presents the expressions which give their value for different types of short-circuits.
