Abstract: Shipboard integrated power systems (IPS) combine a traditional marine independent mechanical propulsion system and a power system in the form of electrical energy, which is an important trend of warship power systems at present. Hence, it is necessary to have an in-depth understanding of IPS's constitution, development trends and approach to construct. Compared with land power grid, this thesis tackles the significant characteristics of shipboard IPS, probes into the researches and development tendency of relative technologies, contrasts and summarizes typical analysis and evaluation techniques of shipboard IPS, such as power flow calculation analysis, reliability evaluation and risk assessment, to provide a theoretical basis for the design, construction, operation and maintenance, management and control. It indicates that internet of things technology, 5G communication technology, multi-core CPU technology and information interaction and fusion will be effective approaches in meeting all kinds of challenge faced by the future development of shipboard IPS . Moreover, the technologies including intelligent sensing measurement, intelligent energy management, intelligent fault reconstruction, etc., will be the essential foundation of shipboard IPS, to maximize the combat capability and survivability of warship.
