摘　　要：在市场存在巨大需求和国家政策支持的双重利好下,近些年在全国掀起一股数据中心建设热潮。数据中心对供电可靠性和安全性要求比较高,特别是高等级数据中心,除常规配置双重10 kV市电电源外,还配置有多重后备保障电源(如柴油发电机组、UPS、EPS和高压直流等)。在国内部分经济较发达地区,出现不太常见的20 kV等级供电电压。将结合实际工程案例浅谈20 kV供配电系统在数据中心的应用,以及如何选择匹配的变压器和柴油发电机组的电压等级。Under the double favorable of market demand and the support of national policies,in recent years,a data center construction boom has been set up across the country.The data center has high requirements for power supply reliability and safety,especially for high-grade data centers.In addition to the conventional confguration of dual 10 kV mains power supply,it is also equipped with multiple backup power supplies(such as diesel generator sets,UPS,EPS,high voltage DC,etc.).Below,the application of the 20 kV power supply and distribution system in the data center and how to select the matching transformer and diesel generator voltage level are discussed in combination with the actual engineering case.
