Data center power supply system and method

The invention discloses a data center power supply system and method, and relates to the technical field of power supply and distribution, and the data center power supply system comprises a high-voltage AC power supply, a high-voltage bus, a generator set, a transformer, a low-voltage bus, a storage battery pack, an AC/DC converter, and a load. The high-voltage alternating-current power supply and the generator set are connected with the high-voltage bus, and the generator set is used for providing electric energy for the load when the high-voltage alternating-current power supply is powered off; the high-voltage bus is connected with the low-voltage bus through the transformer. The transformer is used for converting high-voltage electric energy transmitted in the high-voltage bus into low-voltage electric energy and transmitting the low-voltage electric energy to the low-voltage bus. The storage battery pack is connected with the low-voltage bus through the AC/DC converter, and the load is connected with th
