Highly reliable power supply system solution for data center

Detailed plan description

For IDC data centers, enterprise computer rooms, and computing centers, we provide a highly reliable overall power supply system solution that meets Tier III/Tier IV standards, covering the full link of medium-voltage incoming lines, transformers, low-voltage distribution cabinets, UPS uninterruptible power supplies, precision column cabinets, bus ducts, and diesel generator sets. It adopts a redundant architecture design and is equipped with an energy consumption management system to ensure zero interruption of power supply while reducing the overall PUE value.

Adapted to Indonesia

Solve the problems of "insufficient capacity, UPS redundancy, PUE pressure, short maintenance windows, and high downtime losses" for data centers, AI computing computer rooms, and enterprise computer rooms. The plan comprehensively plans medium and low-voltage power distribution, UPS, PDU, bus duct, diesel engine, monitoring and maintenance bypass, and supports N+1/2N architecture and phased expansion.

Professional specifications and standards based

The low-voltage system is based on 400/230V, 50Hz; UPS recommends online double conversion, N+1 or 2N; the cabinet-side PDU supports branch metering, and the bus duct is calibrated based on short-circuit capacity and temperature rise. References IEC 62040, IEC 61439, IEC 60364, IEC 60529, IEC 60947 and can align with Uptime Tier design principles and local fire/machine room codes.

Original experience and test data

Scarce experience: Data center power supply is most afraid of a single point of failure and cannot be switched during maintenance.

Pitfalls and pain points that I have stepped on

• Single-path power supply has the risk of single-point failure. Once the power is cut off, data loss and business interruption will be caused, and the losses will be immeasurable;
• The server load generates a large amount of harmonics, which pollutes the power grid, accelerates equipment aging, and even causes downtime;
• Distribution energy consumption accounts for a high proportion, PUE values remain high, and operating costs continue to rise;
• Later expansion will require shutdown for construction, which will affect online business operations.

Core parameters

Power supply level Tier III/Tier IV, UPS backup power supply time 15~30 minutes, diesel generator set N+1 redundant configuration, system PUE≤1.3, power supply reliability 99.999%, voltage deviation ≤±2%.

Our special contribution

• Dual bus 2N redundant architecture, zero impact of single point failure, fully meets the highest Tier IV availability level;
• Configure active power filters to accurately control harmonics, protect IT equipment, and extend the service life of equipment;
• Intelligent bus duct + full-link energy management system can reduce PUE by more than 0.15;
• Modular design supports online hot-swappable capacity expansion, and construction does not interrupt business operations.

Project income

• Economic benefits: The PUE is reduced by 0.15, and the annual electricity bill of the thousand-rack data center is saved by more than 1.5 million yuan; after harmonic control, the service life of IT equipment is extended by 20%, the equipment update cycle is lengthened, and the average annual depreciation cost is reduced by 15%.
• Security benefits: 99.999% power supply reliability, annual downtime is less than 5 minutes, completely eliminating data loss and business interruption losses caused by power outages; single point failure does not affect business, and availability reaches financial grade standards.
• Management benefits: Online hot-swappable capacity expansion, zero business interruption during expansion construction, shortening the service rollout period by 60%; full-link energy consumption is visualized, and energy-saving transformation can be implemented accurately.
