This article presents the harmonic analysis of transformer inrush currents in offshore power systems. Offshore production facilities interconnected by subsea cables are becoming increasingly common, either as new projects or as extensions to existing facilities. Interconnection via a subsea cable introduces a significant shunt capacitance to the source power system, giving rise to low natural or resonant frequency. One source of harmonic currents is the system transformer. When initially… CONTINUE READING
