Launch of 6300kVA Smart Green Data Center Solution

Based on in-depth insights into the core operational needs of data centers, this solution creates a comprehensive demand response mechanism.

In terms of power security, it accurately matches the total load of 6300kVA (approximately 4500kVA for IT equipment and 1800kVA for supporting facilities such as cooling, lighting, and operation & maintenance), and realizes efficient power supply through refined load distribution and dynamic adjustment. It enables efficient voltage conversion from 35kV to 0.4kV, with voltage fluctuation strictly controlled within ±5%. The dual-system redundancy design supports seamless fault switching and meets the "N+1" standard to ensure continuous business operation.

In terms of energy efficiency and reliability, the solution adheres to the first-class energy efficiency standard, with special optimization for cooling system and power conversion losses. It achieves a Mean Time Between Failures (MTBF) of ≥ 100,000 hours and a Mean Time To Repair (MTTR) of ≤ 30 minutes, supporting 24/7 uninterrupted operation of core businesses. In addition, the solution reserves 20% of power capacity and cabinet space to adapt to future business expansion and equipment upgrades. It complies with multiple national standards related to power safety, fire protection, and environmental protection, has obtained ISO27001 information security certification and green data center certification, and is equipped with an intelligent operation and maintenance system to realize full-process efficient management and control.

Adopting a "modular, dual-redundant, fully intelligent" design, the solution builds a collaborative system of four core modules. It not only ensures independent redundant operation of each module but also realizes efficient linkage, comprehensively improving system performance.

1. Power System: Dual Redundancy Architecture to Consolidate the Foundation of Stable Power Supply

It adopts a 35kV dual-circuit independent power supply design, paired with dual Gas Insulated Switchgear (GIS) equipment and dual main transformers. A single system can carry 100% of the load; in case of a main power failure, the high-voltage automatic transfer switch can switch to the backup power supply within 0.5 seconds to ensure uninterrupted power supply. Two 6300kVA first-class energy efficiency oil-immersed (or dry-type) power transformers are equipped, using a dual-split winding design to realize independent operation and balanced load distribution of the two low-voltage systems. Intelligent temperature control and online monitoring equipment are also configured to provide real-time protection for equipment safety. The low-voltage power distribution system adopts a dual-bus architecture, and the SVG reactive power compensation technology ensures that the power factor is stably maintained above 0.95. The "modular UPS + lithium iron phosphate battery" configuration achieves 96% full-load efficiency and 92% light-load efficiency, reducing battery volume by 50% and extending service life to over 10 years. A Battery Management System (BMS) is also integrated to realize precise monitoring and balanced charging.

2. Cooling System: Precise Temperature Control as the Key Support for Green Energy Conservation

The cooling module innovatively adopts a hybrid cooling solution of "in-row precision air conditioners + free cooling", combined with closed cold aisle technology. In-row air conditioners are deployed adjacent to IT equipment to shorten the cold air delivery distance, reducing cooling losses by more than 30%. The closed cold aisle completely isolates hot and cold air to avoid hot air recirculation. The 1240kW-class in-row precision air conditioners use high-efficiency EC fans and variable-frequency compressors, supporting dynamic adjustment of cooling capacity from 10% to 100% to adapt to changes in IT load. When the outdoor temperature is ≤ 15°C, the system automatically switches to the free cooling mode, introducing outdoor cold air for direct cooling through a plate heat exchanger and shutting down the compressor, reducing cooling energy consumption by more than 70%. When the outdoor temperature exceeds 15°C, it automatically switches to the mechanical cooling mode to maintain a stable environment in the computer room with a temperature of 20-24°C and a humidity of 40%-60%.

3. Cabinet Wiring: High-Density Layout Balancing Standardization and Efficiency

The cabinet wiring module adopts a "micro-module" layout. Each module includes 16 42U high-density cabinets, two in-row air conditioners, and a closed cold aisle, with a 1.2-meter maintenance channel reserved between modules. The cabinets are made of high-strength cold-rolled steel, with a load-bearing capacity of ≥ 1000kg and a ventilation efficiency of ≥ 75% for the front and rear perforated doors to ensure heat dissipation. Each cabinet is equipped with two intelligent PDU units, which are connected to dual power distribution cabinets to realize dual-power redundancy supply. The wiring system adopts an "upper cabling + cable tray" configuration, with power cables and network cables arranged in separate cable trays for physical isolation to avoid interference. Flame-retardant YJV cross-linked polyethylene insulated power cables, Category 6 unshielded twisted pairs, and single-mode optical fibers are selected to support a transmission rate of 10Gbps and meet future upgrade needs.

4. Intelligent Operation & Maintenance: Full-Link Monitoring as the Core for Efficient Management

Centered on an IoT unified monitoring platform, the intelligent operation and maintenance module integrates data from power equipment, cooling equipment, cabinet devices, and environmental parameters (such as temperature, humidity, smoke detection, and water leakage) to realize "one-map" visual management. The data collection frequency is ≤ 1 second, supporting multi-terminal access via PC and mobile devices. The energy consumption analysis module updates PUE data every 15 minutes, generates detailed energy consumption reports and trend analyses, accurately identifies high-energy-consumption areas, and provides optimization suggestions. The fault early warning system presets equipment fault thresholds; when a threshold is triggered, it automatically activates multi-level alarms such as sound and light alarms, SMS notifications, and APP pushes, accurately locates the fault location and cause, and supports intelligent linkage processing (e.g., automatically adjusting air conditioner fan speed when the regional temperature rises, and automatically activating ATS switching and UPS redundancy modules in case of power failure).

To achieve the first-class energy efficiency target of PUE ≤ 1.25, the solution builds an all-round energy-saving system from three dimensions:

Equipment level: Selects various first-class energy efficiency equipment, reducing overall energy consumption by 20%-30%;

System level: Taps into the potential of free cooling in depth, reducing mechanical cooling operation time by more than 6000 hours annually and improving energy utilization efficiency;

Management level: Realizes dynamic load adjustment through the intelligent platform, establishes an energy consumption evaluation system, and continuously promotes the implementation of energy-saving measures.

The solution formulates a scientific five-phase project implementation plan, covering from demand confirmation to final acceptance and training, to ensure efficient project advancement. In terms of after-sales service, it provides 1-year free on-site maintenance and quality assurance for core equipment, establishes a full-lifecycle equipment management system, and offers regular inspection and upgrade suggestions. These measures ensure that the data center meets the first-class energy efficiency requirements in the long term and adapts to the long-term development of the business.

The launch of this 6300kVA smart green data center solution is an important achievement of our company's technical accumulation and innovation in the data center field. In the future, we will continue to focus on industry needs, deepen R&D, and launch more efficient, reliable, and green solutions to inject strong impetus into the high-quality development of the digital economy.
