In order to solve the problems of fixed model parameters and low efficiency in traditional numerical method software simulation for transformer excitation inrush current. this paper, response surface fitting is applied calculation current, which realizes efficient analysis peak value current with change closing Angle under condition different remanence main column. Firstly, generation mechanism was theoretically analyzed, key influencing factors were extracted. Secondly, parameter modeling used establish converter paper. Finally, between initial winding fitted by test design, accuracy verified. It provides technical reference fast digital twin technology power transformer.
