Abstract:Predmet diplomskega dela je analiza stanja glavnih transformatorjev v Nuklearni elektrarni Krško, ki sta ozko grlo pri prenosu električne energije. Potrebno je določiti parametre novega transformatorja. Potrdila se je pravilnost prehoda na večje enote, saj se je z uspešnimi zamenjavami uparjalnikov, nizkotlačnih turbin in sekundarnih grelnikov povečala delovna moč generatorja iz 650 MW na 730 MW, dovoljuje pa se tudi še dodatna povečanja kapacitet ob dodatnih bodočih tehnoloških izboljšavah. V letu 2012 se je zamenjal še rotor generatorja, z izboljšavami na področju izkoristkov pa se lahko izboljša še moč elektrarne do parametrov, ki jih novi generator dopušča.

Title:DETERMINATION OF PARAMETERS FOR THE SELECTION OF A NEW TRANSFORMER IN THE NPP KRŠKO
Abstract:Master’s thesis analyses the situation of the main transformers in Krško Nuclear Power Plant, which are a bottleneck in the transmission of electrical energy. It is necessary to determine the parameters of the new transformer. It was confirmed the correct choise of the transition to larger units. Power generation was increased from 650 MW to 730 MW due to the successful replacement of the steam generators, low pressure steam turbines and secondary heaters. Larger unit also allows a further increase in capacity with additional future technological improvements. In 2012 the rotor of of the generator was replaced and the power plant with further improvements in efficiency can be improved up to parameters allowed by the new generator.
Keywords:transformer, switchyard, distribution of power and losses, Krško Nuclear Power Plant
