The development of data dependent network technology puts forward higher requirements for the scale of the data center machine room.UPS power supply system is the main power supply mode of data center machine room,its requirements for power supply reliability also become higher.The power supply mode of UPS and the input power of power supply system are analyzed,the reliability of different UPS power supply modes is evaluated by using availability as the evaluation index.The results show that dual bus mode has the highest availability.The design of UPS power supply system in data center machine room should consider reliability,and take the external conditions into account,such as early capital investment and later capaci-ty expansion and maintenance.
