Abstract

Koncept zaštite srednjenaponske mreže na primjeru podatkovnog centra
S obzirom na to da su podatkovni centri dio kritične infrastrukture podliježu strogim zahtjevima za dostupnost i kontinuiteta rada što se direktno odražava na sustav zaštite elektroenergetskog postrojenja. Ovaj rad predstavlja tipičnu topologiju srednjenaponske mreže podatkovnog centra na kojoj se razvija nekoliko sustava zaštite koristeći usmjerenu i neusmjerenu nadstrujnu te zemljospojnu zaštitnu funkciju kao i diferencijalnu zaštitnu funkciju. Izrađen je model s pomoću kojeg su napravljeni proračuni kratkog spoja u srednjenaponskoj i niskonaponskoj mreži. Na temelju prednosti i mana svakog sustava u kontekstu potreba podatkovnog centra odabran je optimalan sustav zaštite za koji je dan prijedlog podešenja zaštitnih releja.

Abstract (english)

The concept of medium voltage network protection on the example of a data center
Considering that data centers are part of critical infrastructure, they are subject to strict requirements for availability and continuity of operations, which directly impacts the protection of the power grid. This work presents a typical topology of a medium voltage network in a data center, developing several protection systems using directional and non-directional overcurrent and ground fault protection functions, as well as differential protection function. A model was created to calculate short circuits in medium and low voltage networks. Based on the advantages and disadvantages of each system in the context of data center needs, an optimal protection system was selected, and a proposal for the setting of protective relays was given.
