Abstract

The traditional harmonic current detection algorithm is cumbersome and complex to implement in MCU. A practical single-phase ip-iq harmonic current detection algorithm is proposed in the paper. According to the characteristics of single-phase circuit instantaneous harmonic and reactive current,the algorithm decompose single-phase grid current based on instantaneous reactive power theory. The new algorithm has been applied as simulation and experimental example to a single-phase PV inverter, and the results show that it is an real-time, stable, reliable detection method which can meet the requirements of the single-phase active filter.
