Abstract
Zadatak rada je dimenzioniranje sustava istosmjernog pomoćnog napona u distribucijskim trafostanicama. Sustav istosmjernog pomoćnog napona u elektroenergetskim postrojenjima se koristi kako bi se osigurao konstantan istosmjerni napon na trošilima iznimne važnosti u havarijski situacijama. Na osnovu tehničkih zahtjeva trafostanice određuje se potrebna trošila. Na osnovu popisa trošila uz poznat zahtjev trajanja autonomije, koja je najčešće 5 sati, određuje se kapacitet baterije istosmjernog razvoda. Provode se kontrolni proračuni pada napona, struja kratkih spojeva, odnosno selektivnosti zaštite u istosmjernom radu. U radu je opisan primjer svih proračuna istosmjernog razvoda 110V s ugrađenim kapacitetom baterije 320 Ah.
Abstract (english)
The task of this paper is the design of the direct current auxiliary power system in distribution substations. The DC auxiliary power system in electrical facilities is used to ensure a constant direct current voltage supply for very important loads during emergency situations. Based on the technical requirements of the substation, the necessary loads are determined. Using a list of loads along with the known requirement for autonomy duration, which is typically 5 hours, the capacity of the DC distribution battery is determined. Control calculations are carried out for voltage drop, short circuit currents and protection selectivity in DC systems. In this paper i described an example of all calculations for 110V DC system with 320 Ah built in capacity.
