Research on switching control logic of mains and backup power sources in data centers
CHEN Yi-xin
Abstract：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.
