A Blend Control Scheme of Active Power Filter Based on Harmonic Voltage
This paper proposes a blend control scheme of APF based on harmonic voltage to solve the problem that load current detection APF cannot change the harmonic impedance in distribution system. In addition, based on the relationship between the rated volt-ampere of APF and the load volt-ampere, the conductance value could automatic adjustment. Computer simulation and laboratory system are designed and constructed to verify the validity and effectiveness of the shunt active filter equipped with the blend control. The shunt active filter with blend control not only can compensate the nonlinear load harmonic current but also can help to damp the harmonic voltage in distribution system.
