Battery System Dimensioning for Data Center Uninterruptible Power Supply Systems

Sustavi neprekidnog napajanja osiguravaju neprekinutu, pouzdanu i visoko kvalitetnu električnu energiju za osjetljiva trošila. Postoje tri glavne topologije statičkog sustava neprekidnog napajanja: UPS dvostruke pretvorbe, linijsko – interaktivni UPS te Stand - by UPS. Neovisno o topologiji, svaki statički UPS koristi baterijski sustav kao spremnik električne energije u slučaju nestanka napajanja iz mreže. U radu je dimenzioniran sustav neprekidnog napajanja i baterijsko rješenje za podatkovni centar na kojemu je IT teret jednak 1000 kW. Dimenzioniranje neprekidnog sustava napajanja i prikladnog baterijskog sustava u podatkovnim centrima odvija se prema zahtjevima snage IT trošila te potrebnom vremenu autonomije sustava.Uninterruptible power supply systems ensure uninterrupted, reliable, and high-quality electrical energy for sensitive loads. There are three main topologies of the static UPS systems: Double Conversion UPS, Line – Interactive UPS, and Standby UPS. Regardless of the topology, each UPS system uses batteries as a power supply in the event of a power failure. This thesis describes the dimensioning of battery system solution, as well as the uninterruptible power supply system for the data center with 1000 kW IT load. The dimensioning of an uninterrupted power supply system and the appropriate battery solution for the data center purpose is done according to the IT requirements of the load and the required system autonomy
