As the core service carrier of China Telecom Henan Branch, the provincial hub building has experienced a steady growth in overall power load due to the continuous expansion of core network and computing equipment. The existing backup generator system suffers from insufficient capacity and low operational redundancy, which fails to satisfy the emergency power supply requirements for core telecom equipment and introduces potential power safety hazards. This power supply and distribution expansion project was launched to enhance the site's uninterruptible power supply capability and resolve existing power capacity deficiencies.
The project deploys four 2000kW diesel generator sets (16VC configuration), delivering a total standby power capacity of 8000kW. The units are fully compatible with the hub building's existing high-voltage power distribution and UPS systems. They support multi-set parallel operation, automatic load sharing, seamless transfer between utility power and generator power, and automatic fault protection. Under utility power failure conditions, the generators can provide continuous and stable backup power for core communication and computing devices, fully complying with the reliability standards for provincial-level telecom hub stations.
The project was implemented in strict compliance with national and industrial specifications for communication power supply and data center infrastructure construction. The scope of work included foundation fabrication, equipment hoisting and installation, power cable routing, control system wiring, and grid-connected linkage commissioning. Construction was carried out in a non-service-interruption manner with phased and partitioned operation to ensure stable operation of in-service equipment. Comprehensive tests, including single-unit startup, parallel operation and emergency transfer switching, were completed, with all technical parameters and performance indicators fully meeting acceptance criteria.
The project completed full commissioning, inspection and acceptance and was officially delivered and commissioned in August 2022. The renovation effectively resolves the original power capacity bottleneck, improves the emergency power redundancy and fault resilience of the hub station, and provides a highly reliable power guarantee for the stable operation of provincial core communication networks, computing infrastructure and critical government and enterprise services.
