Power System Configurator - AI Data Center Configurator

Distribution architecture (typical chain)

Utility 10kV→ HV switchgear→ Transformer 10kV/0.4kV→ LV switchgear→ UPS→ RPP / PDU→ IT racks

Large AI data centers often use 2N dual feed. For high-power-density AI zones also consider per-rack PDU capacity and busway selection.

Input parameters

Number of racks

racks

Average power per rack (IT load)

kW/rack

Typical: standard racks 4–8 kW, high-density AI / liquid-cooled 20–100+ kW

Average IT load factor (actual / rated)

Servers typically run at 50%–80%; idle units still consume power

PUE (power usage effectiveness)

1.1 excellent1.52.5 poor

PUE = 1.50

PUE = total data-center power ÷ IT power. Regulations require new large data centers to reach PUE ≤ 1.3

UPS & battery quick sizing

Auto-matches mainstream high-power 3-phase UPS and LFP smart lithium battery cabinets from the effective IT load above. Capacities are typical ratings; final selection per vendor manual. UPS capacity already includes redundancy factor and 20% design margin.

UPS capacity needed — kVA Battery capacity needed — kWh UPS redundancy Battery backup time

High-power 3-phase UPS (IT load, incl. redundancy & margin)

Brand / series

Recommended model	Capacity / unit	Units	Total capacity	Full-load input / unit	Total input power	Note

LFP smart lithium battery cabinets (capacity by backup time)

Brand / series

Recommended model	Capacity / cabinet	Cabinets	Total capacity	Footprint ref.	Note

Same basis as the “Backup Power” page: UPS capacity = IT load ÷ 0.9 × (1 + 20% margin) × redundancy factor (N+1 = 1.25, 2N splits across two buses); battery capacity = IT load × backup hours ÷ 0.94 (UPS efficiency). Unit counts are the minimum integer combination meeting the demand; for small loads pick smaller models and verify modular scalability.

LV switchgear & ATS quick sizing

Auto-matches LV switchgear (main incoming / busbar), smart rack power panels (one per row) and ATS automatic transfer switches (mains/genset) from total power. Capacities are typical ratings; final selection per vendor manual. ATS demand links to genset capacity on the “Backup Power” page.

Brand / series

Recommended model	Rated current	Units	Switching capacity	Note

Basis: total incoming current = total power ÷ 0.9 (apparent kVA) × 1.443 (400V 3-phase); RPP incoming rating by row load current; ATS switching current = genset kVA × 1.443 (ATS must carry full genset output). ATS is a PC-class transfer switch (GB/T 14048.11); in a 2N architecture each bus gets one unit. Feeder board count is an estimate by rack count; final circuits need detailed design.
