Research and application of excitation inrush current suppression technology for transformer in isolate power grid of offshore oil field

The inrush current generated when the transformer is closed affects the safe and stable operation of the power system of offshore oil island power grid. The causes of excitation inrush current are analyzed, combined with the characteristics of isolated power grid in offshore oil fields, a scheme to restrain transformer excitation inrush current is put forward, and has been well applied in practice.
