摘　　要：比较国内外数据中心相关规范的不同分级标准及应急发电机系统的冗余措施,针对数据中心的主要负载为UPS电源和大型冷冻机的特点,提出发电机组容量的计算方法。从配电柜的额定电流、短路电流,以及经济性等方面深入分析如何合理选择发电机系统的电压等级。提出确定大型发电机系统控制策略时需关注的问题,以及与发电机系统可靠运行紧密相关的其它细节问题。In this paper, different grading standards in relevant codes of data centers home and abroad and their emergency generator system redundancy measures are compared. The calculation method of generator set capacity is proposed based on the fact that the main loads of the data center are UPS and large refrigerator, How to select the voltage level of a generator system is analyzed in depth from the aspects of the rated current of distribution cabinet, short-circuit current as well as economy, etc. Concerned problems in determining control strategy of large generators as well as other minor problems closely related to reliable operation of the generator are proposed.
