Abstract:Luojing container terminal renovation project is a “bulk-to-container” functional transformation project.It involves redesigning and constructing the existing Luojing bulk cargo terminal into a fully automated container terminal model.After the conversion from bulk cargo to containers,both the types and capacity of the electrical load in the port area have significantly increased,with dynamic changes in demand across different phases.The main challenges include:how to carry out the renovation of the power supply and distribution system based on the existing two 35 kV main step-down substations in the original bulk cargo port area,how to ensure the orderly integration of the power supply and distribution system and pipeline network with subsequent phases during the construction of the fully automated container terminal,and how to enhance the stability and reliability of power supply system of the terminal.Considering the current conditions of the Luojing bulk cargo port area and relevant regulatory requirements,an overall upgrade and load distribution plan for the power supply and distribution system and a “master planning,phased implementation” approach for the power supply and distribution system and pipeline network are developed,research and analysis are carried out on the construction of intelligent power distribution systems in ports,and corresponding solutions and measures have been implemented,which can serve as a reference for the design of power supply and distribution systems in similar port projects.
