| description | As the harmonic pollution of power grid is becoming increasingly seriously, harmonic and reactive detection has became one of the key approaches of power quality improvement. It analyzed amply a harmonic current detection method based on the two-dimensional spread theory and a fast harmonic detection method based on the active current separation theory which has no phase locked loop (PLL), and verified them by Matlab/Simulink. Simulation results show that these two methods can detect harmonic and reactive currents of single-phase circuit real-timely and accurately under ideal conditions, and the algorithms are simple and easy to implement; but once the grid voltage distorts and the fundamental frequency offsets, the harmonic current detection algorithm of single-phase circuit based on the active current separation theory has a higher accuracy. |
