摘　　要：数据中心行业中大量使用柴油发电机组作为长时间运行的备用电源,但是由于机组系统比较复杂,用户经常在做功率选择、设备配置时感到迷惑。本文针对行业用户经常不理解柴油发电机组的功率定义,简要归纳了国标中各种功率定义的特征,并且分析了国标和通信行业标准中柴油发电机组功率定义的异同点,给出数据中心用柴油发电机组功率选择建议。总结了数据中心高低压柴油发电机组系统常用的建设架构,分析了高压机组与低压机组在建设中的优缺点。最后对系统中常用器件的短路计算和选择方法给出算例,为数据中心备用柴油发电机组供电系统的设计和建设提供参考。Diesel generators are widely used in data centers as long running backup power supply. Users are often confused when making power selection and equipment configuration due to the complex systems.This paper briefly summarizes the characteristics of various power definitions in the national standard and analyzes various power definitions of diesel generator set in national standard and communication industry standard. This paper gives power selection suggestions for diesel generator set used in data center,summarizes common construction architecture of high and low voltage diesel generator set system in data center,and gives calculation example of short circuit calculation and selection method of common components in system,which provides reference for design and construction of power supply system of standby diesel generator set in data center.
