Synchronous generators for all electric cruise liners: Evolution, requirements and future trends

This paper presents a critical review of the evolution that electric generators installed on board all-electric modern cruise liners have undergone in the past decade. The aim is, through the deep understanding of the real operating conditions of a passenger fleet, to capture evolution trends and to project them into a near future scenario. This scenario is to constitute a valuable tool to ascertain which improvements are to be considered beneficial for the application, thus providing a competitive advantage to suppliers and a valuable asset for ship-owners. Such future scenario includes new generating trends for conventional (Medium Voltage AC) as well as a sight into future new Integrated Power Systems based on Medium Voltage Direct Current technologies.
