Description

This contribution focuses on a lumped-element parameter extraction of a finite-element three-phase transformer model. The two-dimensional transformer model is simulated using the $A$-formulation in the finite-element solver openCFS. The lumped-element model is based on modified nodal analysis and utilizes Hopkinson's analogy to derive a magnetic equivalent circuit. The core in both approaches is described using a saturation function. The parameter extraction of the finite-element model for the lumped element model is discussed practically, and the simulation results are compared.
