Abstract

The invention provides a power supply system and a power supply method. The power supply system comprises at least two first power supply circuits, at least two main transformers and a standby transformer. The at least two first power supply circuits are used for transmitting electric energy to a load. And the at least two main transformers are respectively connected with the corresponding first power supply circuits and are used for transforming the input electric energy and providing the transformed electric energy to the first power supply circuits. The standby transformers are used for transforming input electric energy, the first power supply circuits corresponding to the at least two main transformers are connected with the output end of the same standby transformer, and the standbytransformers are used for replacing the main transformers to provide transformed electric energy for the corresponding first power supply circuits.

Description

technical field [0001] This specification relates to the technical field of power supply, in particular to a power supply system and a power supply method. Background technique [0002] In the substation that supplies power to the data center, there are generally a main transformer and a backup transformer. The backup transformer undertakes the voltage transformation function under abnormal operating conditions of the substation or when the main transformer is out of operation for some reason. [0003] For substations in high-level data centers, each main transformer corresponds to a backup transformer. This configuration can achieve full-capacity backup, but the construction and operation costs are relatively high. Contents of the invention [0004] According to the first aspect of the embodiments of this specification, a power supply system is provided, and the power supply system includes: [0005] at least two first power supply circuits for delivering electric energy...
