Abstract: |
The transform of stationary frame to rotating frame is theoretically studied for detecting the harmonic and reactive current in single-phase circuit,based on which a new model is built. Its correctness has been verified by the theoretical analysis and computer simulation. It can quickly check out the harmonic,fundamental active and reactive currents. |
