The Study on Detecting Method for Harmonic and Reactive Current in Single-Phase Circuit

The instantaneous reactive power theory is widely used in the detection of harmonic and reactive current, and can also be used in single-phase circuit detection. A detailed deduction to the method of constructing two-phase system based on the instantaneous reactive power theory is presented. Aiming at the shortages in existing documents an improved algorithm to obtain the key circuit components is presented. By completing theoretical analysis, many simulations have been achieved and illustrate the effectiveness and performance of the proposed method.
