At present, the world is heading for the information age. The interconnection of the countries along the belt and the road is inseparable from information technology. Strengthening the information infrastructure construction of "one belt and one road" is an inevitable requirement for building the "one belt and one road". China Unicom's one belt and one road (Xinjiang) data center project is an important part of the construction of the information silk road. As a provider of high-end emergency power supply system solutions, Calsion has won the favor of the project at an international and professional level, providing power protection for it.
Project Background
The project is located in Xinjiang Information Industry Park, Changji City, with a total investment of 800 million yuan, covering an area of 150 mu and a total construction area of about 83000 square meters. After completion, the total number of aircraft will exceed 10000, with the bearing capacity of 100000 servers, and the annual output value is expected to exceed 500 million yuan.Project Requirements
Once the data center is interrupted for a long time, the data will be lost and the server will stop running. Therefore, the stability of the data center operation determines that the data center must have a reliable and stable power supply. In the existing technology and power environment, it is urgent to match the emergency diesel generator set to ensure the stability of the power supply in the power center.
Project Research
Under the existing urban power distribution system, it is of great significance to build a reasonable emergency power supply and distribution system for the data center. According to the statistics of emergency electric load of power center and considering the progress of customers' entering, three 2000KW / 10KV high-pressure diesel generator sets will be built in the first phase, and 11 (10 + 1) 2000KW high-pressure diesel generator sets will be configured in the final phase. All units are sent to 10KV oil turbine bus section for power generation, and then sent to 10kv High-voltage Distribution System incoming terminal for switching, and the unit start and stop are adjusted by the unit's own control system according to the load. Combined with the actual demand and automation design of enterprise production, diesel generator set should have the functions of automatic synchronization, automatic parallel operation, automatic load distribution, fault protection, etc.
Solution
In view of the needs of enterprises and the stability, advancement, energy conservation and environmental protection of diesel generating sets, the 3 main 2000KW diesel generating sets are provided by Calsion, and the final stage can be extended to 11 (10+1) 2000KW high voltage diesel generators. In case of mains power failure, the generator unit will be started and operated at the same time. The automatic parallel power supply and automatic load distribution can control the input and output of each unit in the parallel system according to the load size. At the same time, from project selection, system design, scheme optimization to project implementation, technical support, we provide customers with comprehensive emergency power system solutions and turnkey projects.
China United Network Communication Group Co., Ltd. (hereinafter referred to as "China Unicom") was incorporated on January 6, 2009 on the basis of the former China Netcom and the former China Unicom. It has branches in 31 provinces (autonomous regions, municipalities directly under the central government) and many foreign countries and regions. It is the only telecom operation enterprise listed in New York, Hong Kong and Shanghai at the same time. It has been selected as one of the "top 500 enterprises in the world" for ten consecutive years and ranked 273rd among the "Fortune 500" in 2018.
China Unicom's one belt and one road (Xinjiang) data center project construction standard will adopt the T3+ certification standard, use the international and domestic leading level of energy saving and emission reduction technologies, and build a truly green data center. The center has the differentiation advantage of "cloud network integration, independent advanced, safe and controllable", providing support services for Changji's "Internet +" industry, serving Xinjiang and facing the Western China and the countries along the Silk Road Economic Belt. It is an important part of the strategic layout of China Unicom's national cloud data center.
