Backup power design: UPS and standby generators
Guaranteed and emergency power — UPS, rotary UPS and standby generators — for buildings that cannot switch off. From the power balance to blackout tests.
Scope
What the design covers
- Critical load power balance and resilience class (N+1, 2N, Tier)
- Static UPS and rotary UPS (DRUPS): rating, autonomy and configuration
- Standby generators: sizing, single or parallel operation, location and coordination with other trades (fuel, ventilation, exhaust)
- Automatic transfer switching between mains and generator
- Guaranteed-power switchboards, A/B paths, protection selectivity
- Power for server rooms, fire and voice alarm panels, medical and airport equipment
- UPS and generator monitoring in the BMS
- Fire safety expert approval and designer's site supervision
