| Abstract: |
| The control methods of traditional power filter are analyzed and the intelligent compensation factor is introduced to the control method of hybrid filter to suppress the effect of grid parameters on its performance in filtering and reactive compensation. A three-phase hybrid filter algorithm based on wavelet analysis and genetic neural network is proposed，which applies the wavelet algorithm to detect the harmonics of grid current and load current，takes the detected results as the samples to train the genetic neural network，predicts the effect of present network parameters on filtering，and calculates the intelligent factor for compensating the hybrid filtering control. Experimental results show that the proposed control method for hybrid filter improves its dynamic performance and reduces the harmonics effectively. |
