380 Vdc Architectures for the Modern Data Center
This paper presents an overview of the case for the application of 380 Vdc as a vehicle for optimization and simplification of the critical electrical system in the modern data center.
View DetailsDuring the period from 8:25 to 17:07, the PV power generation is higher than 17.5 MW. Therefore, during this time, the power consumption of the data center can be fully supplied by the PV system, and the excess PV power is used for the charging process of CAES system to compress the air and store the compressed energy.
The connection can be accomplished during initial installation, during expansion, or anytime renewable resources are added without impact on ac distribution infrastructure. The application of 380 Vdc to the modern data center has significant implications that will be developed more fully in additional papers as summarized below:
An attractive alternative to meet the objective of improving efficiency and improving (or maintaining) site availability is the application of 380 Vdc distribution rather than ac voltages in data center power distribution or 48 Vdc in telecom facilities.
Specifically, the Standard defines a nominal 380 Vdc-PDS infrastructure that interconnects sources of power to devices in the data/telecom center that draw the power. Provide for the use of safe power levels, as defined by the 2011 NFPA® National Electric Code® (see Related Documents Section 2.).
