Phase I of the Phase III IDC Electromechanical Construction Project of the Central Big Data Center (Wuchang) mainly covers the emergency standby power system, equipped with 7 sets of 16VC-series 2200kW data center-specific diesel generators. All units were delivered, inspected and fully commissioned in November 2022. After on-site checking, overall debugging, no-load and on-load tests as well as parallel switching verification, all technical parameters and safety indicators complied with relevant standards, and the equipment was officially put on standby.
The 16VC units are tailored for large-scale computing hubs, conforming to the 50Hz domestic IDC power standard with a rated speed of 1500r/min. Each unit has a standby power of 2200kW and a rated continuous output of 2000kW. Adopting four-supercharging parallel technology and an independent single-cylinder single-cover structure, the units feature superior transient speed regulation and strong load capacity that meet the G3 regulation requirements for high-tier data centers. Complying with the GB20891-2014 China III emission standard, the units achieve high operational efficiency and low emission performance.
With a high-strength compact structure and optimized bearing design, the generators deliver excellent seismic resistance and durability, adapting to 24-hour standby and frequent emergency start-up scenarios of IDC rooms. Compared with conventional units, they feature lower energy consumption and a wider economic operating range. The modular design simplifies daily maintenance and reduces overall O&M costs. The 7 units are deployed in cluster mode, supporting individual start-up and multi-unit parallel operation to cope with mains power outages and grid fluctuations, ensuring stable operation of servers, storage and network core equipment.
As a regional core computing hub undertaking government data services, enterprise cloud computing and computing power scheduling, the center requires extremely high power supply reliability. The commissioning of this generator set has perfected the "mains-first, generator-backup" power supply architecture, effectively preventing service interruption, data loss and equipment damage caused by power anomalies. The total installed capacity fully satisfies the full-load demand of the Phase I computer room and reserves sufficient power redundancy for future cabinet expansion and business upgrading.
The completion and operation of this core electromechanical project greatly improves the park's power guarantee capability, meets the construction standards of high-grade data center infrastructure, and provides stable and reliable power support for regional digital economy development, government digital transformation and enterprise cloud services.
