Description: Abstract—Active harmonic resistor (AHR) has been
proposed to damp the resonance caused by reactive
compensation capacitors and line inductance in
power system. In this paper, a specific
current-controlled method for AHR is proposed
and modeled firstly, and then the design strategy
for AHR optimal resistor value is studied in detail.
Simulation and laboratory experiment results
proved that using this proposed current control
method the AHR impedance characteristics can
simulate a resistor in a wide band and AHR can
suppress the harmonic amplification significantly Platform: |
