SETTING A COMPUTER SIMULATION PLATFORM FOR PASSENGER SHIP DC DISTRIBUTION NETWORKS

摘要

Passenger ships have very high requirement for on-board reliability and constant power availability which is very critical for the safety of the passengers and the vessel. Thus, the adaptation of an IPS was early evaluated to be very beneficial. As technology advances, the need for a simulation of the all-electric ship becomes evident, in order to investigate the effect of integrating the appealing DC into the power distribution subsystem of a ship grid, on the overall performance of the vessel. In this paper, a MVDC all-electric ship IPS is modeled from the power generation module to the several distribution loads. In the second part of this work, the effect of a potential fault at the DC subsystem is investigated, in order to fully understand the fault characteristics and impacts. Finally, the necessity of DC grid protection is discussed and some of the dominant fault-interrupting techniques are presented.
