Abstract EN
This paper describes three different ways of transformer modeling for inrush current simulations.
The developed transformer models are not dependent on an integration step, thus they can be incorporated in a state-space form of stiff differential equation systems.
The eigenvalue propagations during simulation time cause very stiff equation systems.
The state-space equation systems are solved by using A- and L-stable numerical differentiation formulas (NDF2) method.
This method suppresses spurious numerical oscillations in the transient simulations.
The comparisons between measured and simulated inrush and steady-state transformer currents are done for all three of the proposed models.
The realized nonlinear inductor, nonlinear resistor, and hysteresis model can be incorporated in the EMTP-type programs by using a combination of existing trapezoidal and proposed NDF2 methods.
