20.500.12556/RUL-30681 Nastavitve frekvenčne in napetostne zaščite ob prehodu v otočno obratovanje Frequency and voltage protection settings at transition in islanded operation mode Diplomska naloga obravnava prehod dela gorenjskega elektroenergetskega sistema v otočno obratovanje in nadaljnje obratovanje v tem režimu. Opisana je problematika otočnega obratovanja z prednostmi in slabostmi, ter glavne razlike z obratovanjem v interkonekciji. V nadaljevanju je opisana regulacija frekvence, napetosti ter delovne in jalove moči. Opisan je obravnavan del gorenjskega elektroenergetskega omrežja, ter njegov model v programskem okolju Matlab/Simulink. V nadaljevanju so opisani rezultati simulacij otočnega obratovanja z različnimi ukrepi, s katerimi poskušamo stabilizirati obratovanje. Obravnavan je prehod v otočno obratovanje po dveh scenarijih. V zadnjem poglavju so predstavljene ugotovitve v obliki smernic in priporočil. This thesis describes transition of a part of a power system of Gorenjska to islanded operation mode and further operation in such mode. Islanded operation mode with advantages and disadvantages and main differences from interconnection operation mode are described. In next chapter frequency, voltage active and reactive power regulation is described. Part of power system of Gorenjska is described as well as its model in Matlab/Simulink simulation environment. In next chapter simulation results with various actions to stabilize islanded operation mode are described. Two scenarios of transition to islanded operation mode are simulated. Conclusions as guidelines and recommendations are presented in last chapter. otočno obratovanje regulacija frekvence regulacija napetosti sistemska zaščita islanded operation mode frequency regulation voltage regulation wide area protection true false false Slovenski jezik Angleški jezik Diplomsko delo 2015-04-01 11:20:02 2015-04-01 11:20:02 2022-08-01 11:09:11 0000-00-00 00:00:00 2015 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 29901 Urh_Matej_-_Nastavitve_frekvencne_in_napetostne_zascite_ob_prehodu_v_otocno_obratovanje.pdf Urh_Matej_-_Nastavitve_frekvencne_in_napetostne_zascite_ob_prehodu_v_otocno_obratovanje.pdf 1 404F63BAF4BEDA6B4A58C54CB1AF0988 b658fd371496aba82b42fabae1aae1a68564db75d5be11e1b51163a27e1837d2 4e373ea1-a1ad-11eb-a523-00155dcfd717 20.500.12556/rul/15149e04-01d0-40ce-824b-9151eda37696 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=30671 Fakulteta za elektrotehniko 0 0 0
