New Method to Improve Electric Quality Based on d, q Transformation

In this paper, a new method based on d, q transformation is put forward to improve electric quality in three-phase system after analyzing and deriving theoretically. Two different application models of the new method are compared, then one is selected to be set up its simulation model and be given simulation study. The simulation results show that the new method can improve the electric quality excellently. Finally, when the new method is put into practice, the problems which should be paid attention to and the main factors which may influence the effect to improve the electric quality are present.
