| Abstract: | Active power filter is an important device to eliminate the pollution of harmonic.A new method of dual filter scheme for harmonic detection based on i_p-i_q principle is presented.The difference value between cut-of f frequency and sample frequency is down when digital low pass filter is impleme nted with digital signal processor (DSP) by the method,which decreases the real time and improves the precision of harmonic detection.Theoretical analysis and simulation results show that the scheme has high performance such as harmonic de tection,simple design and easy implement,and also has some practical values. |
