CabinetThe RS-AHF Active Harmonic Filter is a perfect and comprehensive solution for addressing power qualityissues in the grid, such as harmonics, reactive power, and three-phase load imbalance. The RS-AHF,connected in parallel to the grid, can promptly detect harmonics in the grid, generate a counteractingcompensation current through the converter, and dynamically filter out the harmonics. The operation ofthe AHF is unaffected by various load types and grid structures. It does not produce harmonic fluctuationswithin the system, thereby achieving perfect harmonic control under different loads. The AHF can fullyachieve dynamic reactive power compensation, control capacitor switching, and ultimately improve thepower factor of the grid. Additionally, the RS-AHF has the function of controlling three-phase load currentimbalance, thus comprehensively addressing various power quality issues in the grid.
