摘　　要：供配电系统是数据中心的重要组成部分,从整个数据中心的各个功能担当来看,供配电系统相当于计算机的核心处理器。从规划设计方法、供配电方案选择2个方面进行了详细的阐述。规划设计应充分结合业务定位,遵循现行设计规范和标准,立足现有电能需求,预留未来5~10年的远期电能需求,兼顾系统能源效率指标(Power Usage Effectiveness,PUE)、系统逻辑构架、投资额度等多维度要求。供电方案需充分调研当地外市电稳定性,结合业务定位选择适合自身的供电模式。配电方案中机架数量少(≤100机架)且单一集中时,优选集中式配电模式;机架数量相对较多或存在于多个建筑或单一机房内的设备功能要求逻辑隔离时,优选区域式配电或分散式配电。Power supply and distribution system is an important part of data center,and it is equivalent to the core processor of computer in terms of all functions of the whole data center.This paper expounds in detail the planning and design method and the selection of power supply and distribution scheme.Planning and design should fully combine business positioning,follow the current design specifications and standards,base on the existing power demand,reserve the long-term power demand in the next 5~10 years,and take into account the multi-dimensional requirements such as Power Usage Effectiveness(PUE),system logical framework and investment quota.The power supply scheme needs to fully investigate the stability of local and foreign commercial power,and select the power supply mode suitable for itself in combination with business positioning.In the power distribution scheme,the number of racks(≤100 racks)is small and centralized,and the centralized power distribution mode is preferred;When the number of racks is relatively large or the equipment functions existing in multiple buildings or a single computer room require logical isolation,regional distribution or decentralized distribution is preferred.
