Abstract:In this work, the seamlessly switch systems between shore electricity and ship electricity of dual frequency mode (50Hz-60Hz and 50Hz-50Hz) is proposed. It is mainly used in the power supply of ships (Abbreviated as SEG) which stay in the port, and the problem that the grid needs to be disconnected when the ship is provided with electricity from the shore electricity is resolved. Firstly, the phase locked loop (Abbreviated as PLL) control model is established in seamlessly switch systems between shore electric… Show more
