摘　　要：针对数据中心传统UPS存在长期浮充、利用效率低等问题,提出一种新型光储UPS联合供电系统。首先,针对数据中心的功能需求,构建适合备电加储能的新型光储UPS系统;然后,对新型UPS的蓄电池选型进行了分析,进而确立备电加储能的电池容量计算方法;再者,基于小波包分解算法对光伏出力波动进行平滑,在保证备电的基础上,降低并网光伏的功率波动;最后,通过案例对该策略进行验证。The traditional UPS in data centers has problems such as long-term floating charging and low utilization efficiency.This paper proposes a new type of PV/storage UPS combined power supply system.Firstly,to meet the functional requirements of the data center,a new type of PV/storage UPS system suitable for backup power and energy storage is constructed.Then,the battery selection of the new-type UPS is analyzed,and a battery capacity calculation method for backup and energy storage is established.Furthermore,based on the wavelet packet decomposition algorithm,the PV output fluctuations are smoothed to reduce the power fluctuations of grid connected PV while ensuring backup power.Finally,the strategy presented in this paper is validated through case.
