Abstract：There are design cases for UPS in the form of lithium battery energy storage in Level A data centers,and flywheel energy storage has attracted the attention of some constructors as a new form of energy storage. Taking an actual engineering parameter as an example,this paper analyzes the characteristics of the two forms of energy storage based on the perspective of backup time,service life,cost,power supply reliability and occupied civil construction area attracting the attention of the constructors. The results show that the flywheel energy storage mode is not suitable as a form of UPS energy storage in Level A data centers at this stage,but can theoretically be used in Level C data centers.

摘　要：锂电池储能形式UPS在A级数据中心已有设计案例，飞轮储能作为新出现的储能形式受到了部分建设方的关注。本文以某实际工程参数为例，基于建设方所关注的后备时间、使用寿命情况、造价、供电可靠性、占用土建面积等角度来分析两种储能形式的特点。结果显示，在现阶段飞轮储能模式暂不适合作为A级数据中心UPS储能形式，理论上可以用于C级数据中心。
