Abstract
Diplomski rad podijeljen je na teorijski i praktični dio. U teorijskom dijelu obrađeni su pojmovi vezani uz biomasu i kogeneracijaska postrojena, kao i osnove teorije pouzdanosti. Praktični dio obuhvaća procjenu pouzdanosti distribucijske mreže u koju je uključena elektrana na biomasu Strizivojna Hrast. Procjena pouzdanosti mreže provedena je pomoću analitičke metode pobrojavanja stanja, a zatim i procjena dostatnosti proizvodnje pomoću Monte Carlo simulacije u programu DIgSILENT. Promatrala se promjena indeksa pouzdanosti metodom pobrojavanja stanja u više slučajeva napajanja izvoda na koji je priključena elektrana Strizivojna Hrast. Rezultati su pokazali da je pouzdanost mreže bolja ukoliko se elektrana napaja samo iz jednog izvoda. Rezultati Monte Carlo simulacije ukazuju na povećanje dostatnosti proizvodnje sa smanjenjem ukupnog opterećenja u mreži.

Parallel abstract (English)
This research is divided into theory and practical parts. Terms related to biomas and cogeneration plants, as the ones related to theory of reliability are described in theory part. Practical part encorporates the distribution network reliability assesment of biomas plant Strizivojna Hrast. Network reliability assesment was conducted by analytical method of state estimation, and then by Monte Carlo simulation in the DIgSILENT PowerFactory software. Focus was on the reliability indices changes which were observed by state estimation method in many cases of powerplant feed. The results indicate that network reliabilty is better if powerplant is fed through only one feeder. Monte Carlo simulation results indicate asscending generation adequacy with reduction of total load of the network.
