An Overview of the Application of DC Zonal Distribution System in Shipboard Integrated Power System

In shipboard integrated power system, DC zonal distribution system has advantages in power density improvement, system simplification and modularization, and can effectively improve the continuity and reliability of power supply. This paper introduces the application of DC zonal distribution system in shipboard integrated power system, and discusses the advantages of DC zonal distribution system compared to the conventional one. The key technologies needed to be solved are summarized, and the analyses of practical significance and application prospects are given. Finally, it points out that the issues of system stability, power converters and the DC circuit breakers still need a further study.
