Distribution network project cost data splitting method and auxiliary calculation system

The invention relates to the field of power distribution network engineering, and discloses a power distribution network engineering cost data splitting method and an auxiliary calculation system, and the method comprises the steps: S1, receiving the total cost data of the power distribution network engineering; s2, splitting the total cost data into sub-item cost data of a plurality of subsystems; s3, classifying and classifying the sub-item cost data of each subsystem; s4, determining the affiliation and use of the sub-item cost data of each subsystem; s5, calculating the proportion and proportion of the sub-item cost data of each subsystem in the power distribution network project; and S6, generating split power distribution network project cost data. By splitting the power distribution network into a plurality of subsystems, the cost of the whole project can be estimated more accurately; in addition, for each subsystem, proper splitting methods such as a weighted average method and the like are used to en
