【Abstract】 To dynamically compensate harmonic currents in three-phase circuits, it is very important to detect the harmonic components of the current fast and accurately. This paper proposes a mathematical morphology detection method based on αβ and dq transformation and MATLAB/SIMULINK is employed for the simulation study of this method. The simulation results show that the harmonic current components can be detected fast and accurately by this method with selecting the morphological structure element properly.更多还原
