Abstract

The research on feeder sequence impedance can enhance power quality, reduce the weight of power system and improve the electromagnetic compatibility. In this paper, the sequence impedance with the airplane skin as neutral is analyzed in the large-capacity variable frequency power system. The skin factor and proximity factor which affect resistance, as well as inductance in different frequencies are compared. Finally, the sequence impedances in several typical configurations are contrasted, and some conclusions are obtained.
