Abstract :
By analyzing the methods of harmonic and reactive current detection based on the instantaneous reactive power theory, some improvements for the detection method of constructing two-phase in single-phase circuit is presented, and the key algorithm to obtain the important current components is presented too. By studying on the method of active current separation, a new detecting method for harmonic and reactive current in single-phase circuit is presented. Theoretical analysis and simulation results prove the correctness and effectiveness of the two proposed methods.
