Abstract
U ovom radu je prikazan pogon triju generatora nazivnih snaga 1,5 MVA u distributivnoj mreži spojenih preko glavnog ili pomoćnog izvoda na krutu mrežu. Izvedene su simulacije otočnog pogona generatora i analize sustava prvobitno napajanjem iz glavnog izvoda te zatim napajanjem preko pomoćnog izvoda. Isključenjem krute nadređene mreže na koju su izvodi spojeni promatrane su simulacije otočnoga pogona za različite izlazne djelatne snage generatora i različite iznose opterećenja. Prvotno je provedena simulacija s promjenom opterećenja izvoda i promjenom izlazne djelatne snage generatora dok su dodatna razmatranja obavljena u uvjetima balansa između proizvodnje generatora i potrošnje izvoda. Dobivene vrijednosti simulacije – promjena frekvencije i kuta opterećenja generatora analizirane su da bi se uvidjelo hoće li zaštita detektirati otočni pogon ili ne.

This paper presents three generators with rated power of 1.5 MVA operating on external higher voltage network via main and auxiliary feeder. The simulation of island operation of the system originally supplied by the main feeder and then powered through auxiliary feeder was performed. Island operation was created by simulation of certain feeder triping in cases with different generated active power dispatch and system load values. Additional considerations were performed in terms of the balance between the generated active power and the load in the system. Results obtained in the simulation - changes of the generator frequency and the rotor angle were analyzed in terms of detection of the island operation
