Abstract
The large container harbors are characterized with huge installing capacity for the loading and unloading equipment,high demand for power supply reliability,the intermittence,impact,and bidirectional random power flow for the electric load.A safe and reliable power supply and distribution system is crucial for port operation.Based on one large container harbor,by deeply analyzing the characteristics and distribution detail of various electric loads,several key technical issues in the system design were discussed.By following such design principles as Substations located close to the load center,'N-1'criterion,Reliable wiring,and Reasonable power distribution stages,a systematic solution was proposed,which ensured reliable power supply,safe operation and economy.The above research may serve as a reference for similar projects.关键词
