20.500.12556/DKUM-59740 PRENOVA HE ZLATOLIČJE, ANALIZA OBRATOVALNIH STANJ IN USTREZNOST VN NAPRAV Renovation of Zlatoličje hydropower plant, analysis of operating conditions and the adequacy of HV devices Magistrska naloga v uvodu podaja pregled izgradnje hidro elektrarn na reki Dravi s poudarkom na prizadevanju Dravskih elektrarn Maribor za nenehno izboljševanje in povečevanje proizvodnih zmogljivosti celotne dravske verige. Sledi pregled HE Zlatoličje pred prenovo in razlogov za izvedbo prenove. Podrobneje so zapisana posamezna obratovalna stanja, ki lahko nastopijo v času obratovanja elektrarne. Z rekonstrukcijo hidroelektrarne se je povečal tudi instaliran pretok in nazivna moč elektrarne, za kar je bila izvedena analiza ustreznosti stare in novo vgrajene opreme na nazivne in okvarne tokove. V poglavju preizkušanje generatorja je podana teorija tripolnega kratkega stika, kotne stabilnosti in sinhronizacija generatorja na omrežje, kateri sledi izdelava modelov in izvedba dinamičnih analiz za različne obratovalne razmere v programskem okolju MATLAB/SIMULINK. Na koncu je podan pregled zakonskih regulativ s področja obratovalnega monitoringa elektromagnetnega sevanja za nove in rekonstruirane objekte, katerim sledi izračun elektromagnetnega polja v programskem okolju EleFAnT3D z namenom ugotavljanja vpliva elektromagnetnega sevanja rekonstruiranega objekta na obremenjevanje naravnega in življenjskega okolja z nizkofrekvenčnim elektromagnetnim sevanjem. The introductory part of the master thesis presents the course of construction of the Drava River hydroelectric power plants with a special emphasis on the efforts of the company Dravske elektrarne Maribor, operator of these power plants, for constant improvement of operating conditions and uprating of the generation capacity of the whole power plant chain. The subsequent part contains an outline of the Zlatoličje HPP prior to refurbishment and reasons for refurbishment. Further, individual operational conditions that may occur during the operation of a power plant are recorded in detail. By the refurbishment of the plant, its installed discharge and rated power have increased, for which purpose a compatibility analysis of the existing and the new installed equipment as regards rated and fault currents was carried out. In the chapter on generator testing, the theory of three-pole short-circuit, angular stability and synchronization of the generator to the grid are discussed, followed by the development of models and performance of dynamic analyses for various operational conditions in the MATLAB/SIMULINK program package. The closing part contains an overview of legal regulations relating to operational monitoring of electromagnetic radiation for new and refurbished plants, followed by a calculation of the electromagnetic field in the program package EleFAnT3D to determine the impact of electromagnetic radiation of the refurbished plant relating to burdening of the natural and living environment with low-frequency electromagnetic radiation. hidroelektrarne sinhronski generatorji sinhronizacija stikališče kratek stik stabilnost dimenzioniranje opreme hydropower plants synchronous generators synchronisation switchyard short circuit stability dimensioning of equipment true true false [A.
