Abstract:
With the rapid development of renewable energy technology and its industrial levels,the wind-power generation has become a production pattern of new energies with the most development prospects at present.Due to the actual grid condition of our country,the adaptability to the practical grid has also become the important factors to be seriously considered in the further development of modern wind-turbine technology.The adaptability to the grid for a wind-turbine includes grid voltage sag or swell,grid unbalance,grid voltage harmonic distortion,etc.About this,aimed at doubly-fed induction generator(DFIG) and via analyzing the mechanisms of grid faults and the deficiency of modern wind-power technique,the paper proposed a solution scheme of adopting resonant control with the emphasizing on the discussion about the advantage of resonant control,the consideration of engineering realization and the application on enhancing the adoptability of DFIG to the grid.
