Due to the huge investment and small coverage of shore power facilities,it is not guaranteed that all port ves-sels can use shore power systems at any time.In this paper,a marine mobile power supply system is designed.As a bridge connecting ship to shore,it can provide auxiliary power supply for many harbor ships.A MATLAB/Simulink simulation of voltage and current waveform operating under grid-connected and isolated modes is conducted,which indicates the sat-isfactory dynamic stability of the proposed system.
