Abstract

U ovom radu analiziran je utjecaj distribuirane proizvodnje na struje kratkog spoja u distribucijskim mrežama. U uvodnom dijelu se analizirao uzork pojave distribucijske proizvodnje u svijetu i RH. Uz to dan je osvrt na definiciju distribucijske proizvodnje s obzirom da u literaturi ne postoji opće prihvaćena definicija iste. U ovom dijelu prikazane su najčešće tehnologije korištene u proizvodnji električne energije iz distribuiranih izvora priključenih na distribucijsku mrežu. Prikazani su i kratko opisani osnovni tipovi korištenih generatora. Dalje u radu je dan prikaz izračuna struja kratkog spoja prema međunarodnoj normi IEC 60909. Dani su svi elementi za njenu primjenu pri izračunu struja kratkog spoja u distribucijskoj mreži s priključenim distribuiranim izvorima. Uz to dan je i pregled metoda za smanjivanje struja kratkog spoja. Na primjeru test mreže analizirane su struje kratkog spoja u jednoj distribucijskoj mreži, te prikazano povećanje njenih vrijednosti pri priključku distribuiranih izvora na istu.

Abstract (english)

This thesis analyzed the impact of distributed generation on the short-circuit currents in distribution networks. Introduction presents analysis of the appearance of the distribution of production in the world and Croatia. It presents different definitions of distributed generation, with respect to the contemporary literature. As for the time of being, there is no universally accepted definition. This section presents the most common technologies used in the production of electricity from distributed sources connected to the distribution network. Here are presented and briefly described basic types of commonly used generators. Furthermore, thesis gives an overview of calculating short-circuit currents according to the IEC 60909 international standard. This section describes all elements for application of this standard in a distribution network with distributed generation. In addition, thesis gives a brief description of methods used for reducing the short circuit current. Evaluation of impact of distributed generation is done on a test model. It analyzed values of short-circuit current in a distribution system and its increase in the case of a connection of distributed generation.
