Development of vessel integrated power system

The Integrated Power System (IPS) is not only an important basis of the shipbased high-energy weapons but also a revolutionary way of the developing naval vessel power because it is characterized by lower noise, higher survivability, fewer prime movers, less fuel consumption, and greater convenience for general arrangement. This paper has described both the constitution and the latest developments of IPS, proposed the concept of two-generation IPSs, and presented their remarkable technical characteristics and typical architectures. The quantitative analyses of volume, weight, efficiency, power supply continuity, load flow adjustment and control capability, stability, protection and reconfiguration abilities demonstrate that the second-generation IPS has the advantage over the first-generation IPS. Finally, several key technologies concerning the second-generation IPS that need a breakthrough have been proposed according to the current technical level.
