20.500.12556/DKUM-77678 Ekonomsko tehnična analiza možnosti prehoda napajanja iz 20 kv na 110 kv metalurško kemičnega podjetja Cinkarna Celje d.d. diplomsko delo Economic and technical analysis of the possibility of changing power supply voltage from 20 kv to 110 kv of a metallurgical chemical company Cinkarna Celje d.d. V tej diplomski nalogi je izvedena ekonomsko tehnična analiza prehoda napajanja iz 20 kV na 110 kV ter možnost priklopa na odjemno skupino SN 20 kV zbiralke z lastnimi kabli. V izračunih so preverjene ekonomsko tehnične zmožnosti prehoda na višji napetostni nivo. Izračuni so narejeni s pomočjo Excela in obsegajo: izdelavo dokumentacije, prispevkov za gradbena dela, stroške novih transformatorjev, postavitve novega stikališča ter ostalih stroškov. Cene ne vsebujejo vseh podrobnosti, vendar zadostujejo za odločitev glede prehoda na VN nivo. V zaključku so predstavljeni rezultati in ROI (return of investment). In this diploma thesis, an economic and technical analysis of the power supply transition from 20 kV to 110 kV and the possibility of connecting to the MV 20 kV bus collector with its own cables is performed. In the calculations of such verified economic and technical capabilities of the transition to a higher voltage level. The calculations are made with the help of Excel and include preparation of documentation, contributions for construction work, costs of new transformers, installation of a new switchyard and other costs. The prices do not contain all the details, but they are enough to decide on the transitions at the high voltage level. In conclusion, the results in ROI (return on investment) are presented. napajalna postaja transformator stikališče visoka napetost tehnična analiza. power distribution station transformer electrical substation high voltage engineering analysis. true true false [M.
