Abstract

Controllable reactors are widely used in power systems, analog filtering and automatic devices. Under the condition of strong magnetic bias, the phenomenon of magnetic leakage will cause great difficulties in the precise design of the controllable reactor. It is particularly important to analyze the correlation between saturation phenomena and current harmonics, on this basis, to analyze the magnetic circuit loss, the relationship between magnetic circuit saturation and magnetic leakage, and equivalent magnetic resistance. This article reviews the traditional JA hysteresis model and DC bias, and finds some problems in the current research. Finally, the effect of magnetic leakage and magnetic circuit saturation in the magnetic circuit model was proposed, and then to strengthen the global convergence ability of the iterative operation according to the Ohm's law constraints of the circuit and the magnetic circuit, so as to further improve the accuracy and efficiency of the model and improve the efficiency of stability control, analog filter design, reactive compensation, energy transmission efficiency estimation in the power system.
