Study of mechanism and elimination measure of ferromagnetic resonance in low-voltage power system

In neutral isolated power system, it is easy to generate ferromagnetic resonance under external excitation because of the formation parameters of nonlinear inductance and wire-to-ground capacitance, endanger the safe and stability work of the system. In this paper, the generate mechanism of ferromagnetic resonance is discussed, the scope and the advantages -disadvantages of various elimination measures are analyzed in detail.
