分布式电源DPS在数据中心配电系统中的运用

Application of Distributed Power System in Power Distribution System of Data Center

国内数据中心的配电方式主要采用在线式UPS(Uninterruptible Power System).传统的UPS配电系统结构复杂、扩容及后期维护存在较大难度;系统自损高,效率较低;多为一次性投入,难以实现分期投资及建设的需求;存在谐波干扰问题;基础设施需求面积较大,对土建要求高,特别是建筑承重和结构强度;系统适应性差,难以达到通用化和标准化等。针对传统UPS存在的不足,笔者结合实际工程,从设备原理结构到工程前期规划设计再到后期施工使用,对分布式电源系统DPS(Distributed Power System)在数据中心机房的运用进行了全周期的观察和分析。DPS配电系统的特点和优势在工程实际运用和分析的过程中得到了验证。

On-line IPS(Uninterruptible Power System)is the main mode of power distribution for Data Center in China.The traditional UPS system is complex,takes a one-time investment approach,has high self-loss and low efficiency.It is difficult to expand the capacity,to realize the demand of construction by stages,and maintain it in later period.There is a series of problem of harmonic interference,large area required for infrastructure,high demand on civil engineering,esixvially for building lojad tearing and structural strength,poor adaptability and hardly to reach generalization and standardization.In view of the shortcomings of traditional UPS,the author combined with the actual project through the equipment principle and structure,the early design of the project and the later construction use.the application of Distributed Power System(DPS)is observed and analyzed in data center,the characteristics and advantages of DPS are verified in the process of practical application and analysis.
