Abstract：Series and parallel resonances between capacitance and line inductance may magnify background harmonic voltage in power distribution systems, and worsen power quality. Although a resistive active power filter (RAPF) acting as a harmonic terminator can damp out harmonic propagation, it fails to attenuate the existed harmonic effectively. Thus, this paper proposes a double-RAPF strategy. Besides a RAPF1 with matching impedance is located on the end bus, the new strategy involves an additional RAPF2 with variable gain at special location whose distance from the source of the feeder is a quarter wavelength of the dominant harmonics. The proposed strategy can suppress the harmonic propagation caused by harmonic voltage penetrating from the higher level system and harmonic current injected by non-linear loads. Simulation and experimental results verify the theoretical analysis and demonstrate the effectiveness of the new strategy.
