中文摘要:

      随着直流供电相关技术的发展与成熟，直流供电模式在可靠性、经济性等方面都展现了优于交流供电模式的潜力，成为了当前数据中心建设与改造的重要方向。然而在中国，直流数据中心的电压等级仍未形成统一的标准。基于目前的多站融合新模式提出了一种混合供电架构以及评估方法，从线损、可靠性、升级潜力、设备制造水平、负荷需求等多个方面对3种直流供电架构进行了综合对比，对比结果证明了所提混合通信架构综合性能的先进性。提出的研究方法及结论对于直流数据中心电压等级的标准化以及目前多站融合新模式的建设有重要的参考意义。

英文摘要:

      With the development and maturity of direct current (DC) power supply technologies, DC power supply mode has shown its potential to be superior to AC power supply mode in terms of reliability and economy, and has become an important direction for construction and renovation of current data centers.However, in China, there is still no unified standard for voltage level of DC data centers. A reasonable framework and a evaluation method based on the current new mode of multi-station integration are put forward. Comprehensive comparison has been carried out from aspects of line loss, reliability, upgrade potential, equipment manufacturing level and load demand of the three DC power supply frameworks. Based on the comparison results, the advanced comprehensive performance of the proposed hybrid communication architecture is proved. The research methods and conclusions proposed have important reference significance for the standardization of voltage level of DC data center and the construction of new mode of multi-station fusion.
