Simulation research on parallel hybrid APF based on a non-harmonic detection

APF is a new electronic device which can dynamically suppress harmonic,compensate reactive power and hold broad application prospects.But the traditional harmonic detection algorithms enhance the system's hardware and software costs,and time-delay introduced by the harmonic detection algorithms will have an impact on the performance of compensation.A control method without harmonic detection in APF was researched and the operation was analyzed.Simulation proves the effectiveness of this control method of non-harmonics detection.
