| Abstract: | A new detecting method based on wavelet transform used for unified power quality controller is proposed in this paper.This approach is provided with the characteristic of exactness and speediness compared with other detecting methods.The power quality controller can compensate power system disturbances and hamonics through it quickly.In this paper,this method is tested by computer,the acquired data can demonstrate it's practicability and efficiency. |
