摘　　要：数据中心是重要的数据运行基础设施。近年来,数据信息量呈几何级数增长,设备耗电量巨大,因此需要采用柴油发电机组作为备用电源,以实现市电电源与备用电源之间的切换,保证数据中心服务的正常运行。文章以某数据中心改造项目为例,重点研究其市电电源和备用电源的切换控制逻辑,从柴油发电机并机系统、市电切换PLC控制系统、市电电源与柴油发电机系统切换控制逻辑、市电高低压电源之间的切换控制逻辑、联锁要求等方面进行分析,期望为类似项目提供参考。The data center is an important infrastructure for data operation.In recent years,data information has grown exponentially,and equipment power consumption is enormous.Therefore,diesel generator sets need to be used as backup power sources to switch between mains power and backup power,ensuring the normal operation of data center services.The paper takes a data center renovation project as an example,focusing on the switching control logic of its mains power supply and backup power supply.The analysis is conducted from the aspects of diesel generator parallel system,mains power switching PLC control system,mains power supply and diesel generator system switching control logic,switching control logic between mains high and low voltage power supply,interlocking requirements,etc.It is expected to provide a reference for similar projects.
