The invention belongs to the field of
transformer design, and particularly relates to a
transformer iron core section optimization method and
system based on
dynamic programming, and the method comprises the following steps: 1) inputting a given iron core
diameter and parameter data, and building a
mathematical model of a
transformer iron core section according to a transformer iron core design structure; 2) obtaining a selectable sheet width set according to the established
mathematical model of the cross section of the transformer iron core; 3) according to the selectable sheet width set, establishing a
dynamic programming recursion formula to obtain an optimal result of the cross section of the transformer core; 4) visually displaying the optimal result of the cross section of the transformer iron core, judging whether the optimal result meets requirements or not, and if the optimal result meets the requirements, exporting corresponding document data and uploading the document data to a
database for storage; and if not, returning to execute the step 1). According to the method, the final purposes of
full coverage of scheme combination and
global optimization of the calculation result are achieved, meanwhile, the operation efficiency is high, the
time complexity is low, and the overall cost of the transformer is better reduced through the
global optimal section design.
