中文摘要：

本文提出了船舶微电网概念,对船舶微电网的概念进行了定义和阐述,提出船舶微电网不能以“补充”角色接入船舶主电网,而应该以“船舶功能电网替换升级”的角色接入的研究思路,从而彻底改变传统的船舶电力系统功能网络架构.以四机组单主电站供电的大型远洋船舶电力系统为例,给出了与其相适应的船舶微电网架构形式,分析了船舶微电网独特的运行方式和相对于陆地微电网的差异,探讨了船舶微电网系统须研究的关键技术,最后指出船舶微电网建设对于我国船舶工业发展的意义和实施过程中的优势.

英文摘要：

The innovative concept of ship＇s micro-grid is proposed and defined in the paper. It is considered that ship＇s micro-grid should be accessed the ship＇s main power grid as a role of ＂Replacement upgrade＂ instead of ＂complementary＂. Therefore, traditional ship power system network architecture is completely changed. Taking a large ocean-going ship power system with four-unit single main power station for example, the adaptive architecture form of a ship＇s micro-grid is given, and the ship＇s micro-grid running characteristics and differences with the terrestrial micro-grid are analyzed, and its key technology is also explored. The significance of ship micro-grid construction for the development of China＇s shipbuilding industry and the advantages of implementation process are pointed out.
