“…Experimental and simulation studies of the influence of the residual magnetic flux on the value of inrush current are rarely published and selected results are given in [3,4,22,23]. In [3] and [4] lack a comparison of simulation results with experimental results, which do not allow to validate the models of hysteresis.…”

“…The existence of residual flux may be significant to the maximum value of the inrush current of the transformer and contribute to the undesirable effects of protection systems installed in the power system [2][3][4]. Effects of inrush currents are somewhat limited by the use of appropriate reactors and protection systems with time-lag characteristics.…”

This paper presents the mathematical model of a single-phase multi-winding core type transformer taking into account magnetic hysteresis phenomenon based on the feedback Preisach model (FPM). The set of loop differential equations was developed for a K-th winding transformer model where the flux linkages of each winding includes flux Φ common to all windings as a function of magneto motive force Θ of all windings. The first purpose of this paper is to implement a hysteresis nonlinearity involved in the Φ(Θ) function which also accounts residual magnetic flux. The second purpose of this paper is experimental validation of the developed transformer model in a capacitor discharge test and several different values of residual magnetic flux.

This paper presents the results of the experimental and simulation investigation concerning the influence of remanence in the core of a single-phase transformer at the noload transient state. Experimental studies consisted of the discharge of the capacitor through the primary winding at several different values of the residual magnetic flux. The paper presents a model of the transformer test system, taking into account the magnetic hysteresis phenomenon based on the Preisach model with feedback. The model was used to simulate the transient and steady state of the test system, taking into account the value and the sign of the remanence in the toroidal tape wound core. It was concluded that the induction of remanence has a significant impact on the value of the inrush current. This model can be used for simulation of the transformer systems transient state, taking into account the magnetic hysteresis and the remanence.
