Abstract
Elektroenergetski sustav je složeni sustav koji obuhvaca proizvodnju, prijenos i potrošnju elek- ´ tricne energije. Proizvodnju elektri ˇ cne energije vrše elektrane koje su podijeljenje prema vrsti ˇ energenta koji se koristi za dobivanje elektricne energije. Prijenos elektri ˇ cne energije vrši se pu- ˇ tem energetskih vodova ili kabela. Važnu ulogu u prijenosu imaju i energetski transformatori koji služe za povecanje naponske razine u prijenosu kako bi se smanjili gubitci. Svi elementi elektro- ´ energetskog sustava mogu se nadomjestiti prikladnim matematickim modelima koji su neophodni ˇ kako bi se izvršio proracun mreže koji podrazumijeva odre ˇ divanje naponskih prilika u ¯ cvorovima ˇ i tokova snaga kroz mrežu. U prijenosu takoder dolazi do gubitaka koji mogu biti djelatni i jalovi. ¯ Djelatni gubitci posljedica su radnog otpora u elementima prijenosa, a u cvorištima se manifes- ˇ tiraju padovima napona u odnosu na nazivnu naponsku razinu. Djelatni gubitci proporcionalni su opterecenju ´ cvorišta, a obrnuto propornionalni visini napona u nekom dijelu mreže. Gubitke ˇ ne možemo u potpunosti ukloniti, ali ih možemo smanjiti na prihvatljivu razinu ravnomjernim rasporedom tokova snaga kroz mrežu.
Abstract (english)
Electric power system is a complex system which contains production, transmission and consumption of electric energy. Production of electricity is done by power stations which are divided by the type of energy source that is used for conversion into electric energy. Transmission is done via electric lines or cables. Transformers play an important role in transmission due to their ability to reduce losses in transmission by transforming voltage levels. All the elements inside electric power system can be presented with corresponding mathematical models that are necessary for circuit analysis which means determination of voltage levels and load flows. Transmission also produces losses that can be active or reactive. Active losses are result of active resistance inside transmission elements and they are represented by the voltage drop in network knots. Active losses are proportional to hub loads and inversely proportional to voltage level in the certain network area. Losses are impossible to remove completely, but we can reduce them on acceptable values by equal distribution of load flows.
