A comparison of the brushless doubly-fed generator with different rotor structures

This paper presents the comparison of the wound rotor, the nested-loop rotor and the reluctance rotor Brushless Doubly-Fed Generator (BDFG). Based on the finite element analysis and the experiment test methods, the performance characterization analyses are carried out, including the power winding (PW) voltage, the air gap flux density waveforms and the harmonic contents analysis of the corresponding waveforms and the line voltage, the total three-phase active power and the power factors values of the control winding (CW) changing with the rotor rotation speed. The analysis results are carried out on the Y315 frame size BDFG. The analysis results show that the wound rotor BDFG has a better performance than the other two types rotor BDFG.
