This paper proposes a novel dual-stator brushless doubly-fed generator (DSBDFG) with cage-barrier rotor structure for wind power generation. Due to DSBDFG structure and magnetic field complexity, this paper proposes groove-by-groove method to analyze equivalent current density of control winding and power winding. Meanwhile, divided layers model of DSBDFG is built. Magnetic vector potential is regarded as variables to obtain two-dimensional solution of control winding and power winding excitation. On this basis, electromagnetic parameters of DSBDFG are analyzed, which is verified by finite element method and experiment. Through analysis of the results, it demonstrates the validity and rationality of analytical method.
