摘　　要：船舶中压直流综合电力系统具有高功率密度、高运行灵活性等优势,是我国实施海洋强国战略的重要基础。该论文的第一部分首先分析了船舶电力系统的发展趋势,从拓扑结构、电压等级、接线形式、接地方式等角度梳理了船舶中压直流综合电力系统的特殊系统结构;然后,根据现有文献详细阐述了发电侧整流器、推进变流器、DC-DC变换器等船舶中压直流综合电力系统关键电力电子变换器的研究现状,并进行了详细对比;最后,总结了船舶中压直流综合电力系统与陆上直流微电网的典型差异,并梳理了国内外相关技术标准。Shipboard integrated power system(IPS)is an important revolution of shipboard power system,which has a cross-era significance.However,with the increasement of the shipboard IPS capacity,the conventional low-voltage level shipboard IPS can hardly meet the power demand of shipboard power equipment.The shipboard medium-voltage DC(MVDC)IPS has the advantages of high power density,high operation efficiency,high operation flexibility and high operation reliability,and thus has received widespread attention in recent years.As the first part,this paper focuses on the system architecture and power electronic converter of the shipboard MVDC IPS.Firstly,this paper analyzes the development trends of the shipboard IPS,and makes a comprehensive review of the special system architecture of the shipboard MVDC IPS from the perspectives of topology architecture,voltage level,wire connection type,and grounding mode.(1)Topology architecture.The radial topology is simple,and its system construction cost is low;the zonal topology has high redundancy,good flexibility,and high reliability.(2)Voltage level.With the improvement of shipboard IPS capacity,the voltage level of the shipboard MVDC IPS may reach 24 kV or 30 kV in the future.(3)Wire connection type.Monopole symmetrical connection type is suitable for most shipboard MVDC IPS;for large ship with high power supply reliability requirements,bipolar connection type is better.(4)Grounding mode.For the AC side of the power supply end,the shipboard medium voltage power grid adopts the mode of grounding with large resistor;for the DC side of the load end,the grounding mode of the shipboard MVDC IPS can refer to the grounding mode of the onshore DC microgrid;for the DC side of the power supply end,the mode of grounding with resistors is better.Then,according to the existing literature,the key power electronic converters in shipboard MVDC IPS,such as the rectifier for generator,the inverter for propulsion motor,and the DC-DC converter,are comprehensive reviewed,and detailed comparisons are
