Carbon information calculation system for carbon emission flow

The invention discloses a carbon information calculation system for a carbon emission flow. The system comprises a central server, a plurality of auxiliary servers and a plurality of carbon meters which are dispersedly arranged at different positions of a power system, the carbon meter is used for collecting carbon meter data required by the current carbon meter for calculating carbon information; the central server is used for determining a plurality of power supply branches according to the positions of the carbon meters in the power system and the current directions of the carbon meters; establishing a one-to-one correspondence relationship between each power supply branch and each auxiliary server; each auxiliary server is used for determining a corresponding to-be-calculated power supply branch according to the corresponding relation; and obtaining carbon meter data of each carbon meter in the to-be-calculated power supply branch, and calculating carbon information of the to-be-calculated power supply br
