Measurement based inductor modeling for the purpose of ferroresonance analyses

The paper presents the results of modeling and measuring verification of the nonlinear inductor model. A nonlinear inductor physical model based on a simplified theory was proposed and used in the computations. In the assumption it has to be easy to adapt in a far more complex static and dynamic circuit simulations and suitable for further development. A ferroresonance circuit was chosen as the exemplary measuring base. The waveforms obtained from measurements were used to calculate the parameters of the proposed model. The corresponding circuit has been developed in Matlab environment. Time functions resulting from the simulation have been verified with those obtained experimentally in the laboratory
