Due to the difference of stack yard layout,safe and reliable and diversified demands of users for electricity from traditional terminals,the conventional layout of power supply and distribution plane and system scheme is not fully applicable to automatic container terminals.Based on the characteristics of loading and unloading technology of automated container terminals at home and abroad,we study the differences of power supply and distribution scheme between the automated container terminals and traditional terminals,and put forward several modes of power supply and distribution of automated container terminals.Through quantitative and qualitative analysis of the operation efficiency and reliability,new unmanned substations are built in the rear auxiliary construction area with one substation to one berth power supply scheme,ring-net type box transformer supplies power to refrigerated container and AGV charging station nearby.The comprehensive power supply and distribution mode,serving as a solution to balance the terminal power supply efficiency and safety,is applied to Qingdao Port automated container terminal,and may serve as reference for the future construction of the automated terminal.
