One transformer inrush current calculation method based on field-circuit-network coupled co-simulation

摘要

In this paper, one calculation method based on field-circuit-network coupled co-simulation is presented. Compared with the traditional simplified transformer model, this transformer model takes the nonlinear factors into account, and the accuracy of the simulation results will be improved. The transformer is build with the finite element method by using the software of Maxwell, and circuit of transformer is build by using the software of Simplorer, and the network model is build under Matlab/Simulation's environment. At last, this field-circuit-network coupled model is used to calculate the inrush current of transformer.
