Trends in design, modelling and simulation of integrated propulsion and energy systems

摘要

Integration of propulsion and energy systems on board naval vessels will make these systems more complex and interdependent. An optimum solution requires a comparison of different systems, because of the great variety in available systems. Preferably, this comparison should be made during the pre-design stage of the ship, using modelling and simulation tools. In the near future energy systems of ships will be subject to further technological evolution and integration, because of: (1) technological improvements with the aim of achieving lower life-cycle cost, (2) ongoing development or completely new energy and propulsion system solutions, (3) future legislation, (4) expectations on fuel availability. As propulsion and energy systems are becoming more complex and integrated, using high power electrical distribution networks, complex power electronics and integrated power and platform management systems, it is important to obtain accurate models of existing and (near) future components in order to perform detailed simulation of these networks. This paper discusses the role of the simulation tools the Royal Netherlands Navy (RNLN) is using for design studies and elaborates on the research and development that is performed in modelling and simulation with these tools, related to the above mentioned expectations. Reference is made to international co-operation (NATO, WEAG) in this area. The shift towards integrated full electric propulsion for new ships within the RNLN is demonstrated with a number of design examples of current and future RNLN projects.
