| Abstract: | The traditional control strategy of doubly-fed wind generation is analyzed in this study first. A new control strategy has been proposed in this study with voltage oriented and stator flux oriented vector control in grid side and rotor side of the converter adopted respectively. The traditional control strategy is much complex. The new improved control strategy is much simpler than the traditional one. The digital simulation has been done using the PSCAD/EMTDC platform. The results verify the correctness of the new control strategy. |
