| Abstract: | An approach of detecting harmonic currents based on the instantaneous reactive power theory is analyzed. Its corresponding simulation circuit is built by MATLAB simulation software. The simulation studies about the influence of the high pass filters in the detection circuit on the effectiveness of detection are carried out. The results show that the dynamic response and the detecting precision can greatly be influenced by the cut-off frequency. the order and the type of the high pass filter. The conclusions can provide guidance for designing harmonics detection circuits. |
