N2 - With the stator directly connected to the grid, doubly-fed induction generator is very sensitive to grid disturbance. Demagnetization control depresses the influence of grid fault by accelerating the damping of natural stator flux linkage, improving the performance of doubly-fed induction generator. However, the influence of demagnetization control to the low voltage ride-through capability is still not clear. System performance with demagnetization control is analyzed in this paper. The influence of natural stator flux damping to the low voltage ride-through capability is also discussed in this paper and it is indicated that demagnetization control could minimum the occurrence of crowbar interruptions during balanced grid fault recovery, which is helpful to the system. Simulations have been carried out and the results demonstrated the analysis.
