Power Flow Diagram Analysis

This image illustrates a power flow diagram for a data center or server room, showing the sequential path of electricity from external power sources to the final server equipment.

Main Components:

1. Intake: External power supply at 154 kV / 22.9 kV with 100MW(MVA) capacity
2. Transformer: Performs voltage conversion (step down) to make power easier to handle
3. Generator: Provides backup power during outages, connected to a fuel tank
4. Transformer #2: Second voltage conversion, bringing power closer to usable voltage (220/380V)
5. UPS/Battery: Uninterruptible Power Supply with battery backup for blackout protection, showing capacity (KVA) and backup time
6. PDU/TOB: Power Distribution Unit for connecting to servers
7. Server: Final power consumption equipment

Key Features:

• Red circles indicate power switching/distribution points
• Dotted lines show backup power connections
• The bottom section details the characteristics of each component:
  • Intake power specifications
  • Voltage conversion information
  • Blackout readiness status
  • Server connection details
  • Power usage status

Summary:

This diagram represents the complete power infrastructure of a data center, illustrating how electricity flows from the grid through multiple transformation and backup systems before reaching the servers. It demonstrates the redundancy measures implemented to ensure continuous operation during power outages, including generators and UPS systems. The power path includes necessary voltage step-down transformations to convert high-voltage grid power to server-appropriate voltages, with switching and distribution points throughout the system. This comprehensive power flow design ensures reliable, uninterrupted power delivery critical for data center operations.
