AHF( Active Harmonic Filter)
AHF is an active harmonic filter used in power grid systems. AHF eliminates harmonic currents caused by nonlinear loads in the power grid bus and improves the power quality in the power grid and cover the 2-50th harmonic compensation to meet the IEEE 519 standard.AHF runs in parallel in the power grid bus. Compared with LC series resonant passive harmonic filters, it has the advantages of fast speed, high efficiency, small size and low cost. It is currently the most ideal harmonic filtering device for power grid.
