港口多端口交直流岸电系统的研究现状及展望OA

With the acceleration of globalization and the continuous expansion of international trade,ships,as core carriers of maritime transportation,have drawn widespread attention to their energy supply methods.Traditionally,ships rely on their own generators for power after berthing,which poses problems such as low energy efficiency,high pollution emissions,and insufficient power supply stability.To address these problems,shore-based power supply technology has gradually emerged as a critical development direction for ship energy supply.This paper focuses on the multi-port AC/DC shore power system in ports,introduces the application scenarios and working principles of its DC and AC transmission system.It analyzes the core technologies of rectification,inversion,and control modules,and discusses the advantages of this technology,the risks it faces,and its future development trends.The research aims to provide theoretical and practical references for the technological upgrading and large-scale application of port shore power systems.
