Data centers demand the highest reliability from their hệ thống điện dự phòng. A single power outage can cost millions in lost revenue, SLA penalties, and reputational damage. This guide from Huaquan Power covers everything you need to know about choosing the right generator for your data center — from sizing calculations and redundancy architectures to compliance requirements.
Bước chân 1: Calculate Your Total Load
Accurate load calculation is the foundation of generator sizing. Data center loads have unique characteristics:
- IT Load: Máy chủ, kho, networking — the core computing power draw
- Cooling Load: CRAC/CRAH units, chiller plants — typically 30-40% of IT load
- Facilities Load: Chiếu sáng, bảo vệ, fire suppression — 5-10% of total
- UPS Charging: Recharging batteries after an outage — 10-15% of UPS rating
- Motor Starting: Chiller compressors have high inrush current — critical sizing factor
Sizing Formula
Total Generator kW = (IT Load + Cooling Load + Facilities + UPS Charging) x 1.2 Safety Factor
| Data Center Size | IT Load (kW) | làm mát (kW) | Other (kW) | Máy phát điện được đề xuất (kW) |
|---|---|---|---|---|
| Bé nhỏ (Edge) | 100 | 40 | 15 | 200 |
| Trung bình | 500 | 200 | 60 | 1,000 |
| Lớn | 2,000 | 800 | 250 | 4,000 |
| Hyperscale | 10,000 | 4,000 | 1,200 | 20,000 |
Bước chân 2: Design Your Redundancy Architecture
Data center redundancy is expressed as N+x, where N is the minimum required capacity:
| Dự phòng | Sự miêu tả | Uptime Tier | Ứng dụng điển hình |
|---|---|---|---|
| N | No redundancy — single point of failure | Tier I | Non-critical |
| N+1 | One extra unit — most common | Tier II/III | Enterprise |
| 2N | Complete mirror — no shared components | Tier III/IV | Financial/Healthcare |
| 2(N+1) | Dual system with redundancy each side | Tier IV | Mission critical |
Bước chân 3: Compliance Requirements
NFPA 110 (Bắc Mỹ)
- Mức độ 1: Life safety — must start and accept load within 10 giây
- Mức độ 2: Non-life-safety backup — 60-second start acceptable
- On-site fuel for minimum 8 giờ (Mức độ 1) hoặc 2 giờ (Mức độ 2)
TRONG 16798 / ISO 8528 (Europe/International)
- Nguồn điện khẩn cấp: Class EPS — start within 15 giây
- Chế độ chờ: Class LP — start within 60 giây
Bước chân 4: Select Generator Configuration
For data centers, Huaquan Power khuyến nghị:
- Hoạt động song song: Multiple Máy phát điện synchronized for N+1 redundancy
- Skid-Mounted or Containerized: For rooftop or ground-level installation
- SCR/Emission Control: Meeting local emission regulations
- Giám sát từ xa: IoT-enabled for 24/7 visibility
- Công tắc chuyển tự động (ATS): Seamless utility-to-generator transition
