Abstract:	Delo obravnava zamenjavo relejne zaščite 6 kV razvod lastne rabe bloka 4 v TE Trbovlje. Opisane so izkušnje s tovrstnimi napravami in narejena je analiza izpada bloka zaradi nepravilnega delovanja zaščite. Za osnovo za nastavitev parametrov zaščite smo analizirali kratkostične razmere v tem delu elektroenergetskega sistema in opravili zagonske meritve motorjev. Zbrane informacije so bile podlaga za izračun zaščitnih parametrov. Nastavitve so računsko in teoretično opisane za vsak sklop naprav. Rezultati so podatki za ustrezno koordinacijo zaščitnih elementov.

Title:	PROTECTION REPLACEMANT IN OWN CONSUMPTION SWITCHYARD OF THE BLOCK 4 IN THERMAL POWER PLANT TRBOVLJE
Abstract:	Master thesis deals with the replacement of relay protection on 6 kV distribution of own consumption of block 4 in thermal power plant Trbovlje. The experience with these devices are described and the analysis of the failure of the block due to a protection malfunction is made. As a basis for proper settings of the protection parameters, short-circuit conditions in this part of the electricity system were analyzed and the start-up parameters measurements of AC motors were performed. The information contained herein has been the basis for calculating of the protective parameters. Settings are calculated and theoretically described for each set of devices and installations. Results obtained are parameters for the proper coordination of protective relays.
Keywords:	electrical grid, relay protection, medium-voltage switchyard, short circuit calculations
