现代舰船电力系统容量急剧增大，全电力舰船的实现、敏感负荷和新概念武器的引入使舰船电力系统面临着一系列挑战。介绍了超导磁储能系统（SMES）作为一种新型储能设备的应用研究进展，分析了SMES在舰船电力系统中的潜在应用，最后提出了舰船电力系统中应用SMES的关键课题。

This paper introduces a series of challenges which modern power system in ships are confronted with the realization of All Electrical Ship and the application of sensitive loads and new weapons. The author analyses the potential application in power system in ships based on the development of superconducting magnetic energy storage (SMES) as a new storage device and points out the key topics for application of SMES to electric power system in ships in the future.
