Abstract

In the field of All Electric Ship (AES) design, increasing importance is assigned to simulation tools. Shipyards adopt simulation tools to solve design problems and achieve improved efficiency and relevant cost savings in the electrical systems. The calculation of harmonic pollution is one of these design problems. The paper proposes a simplified approach for modeling the very sophisticated MV plant of an all-electric cruise-liner. Having assumed reasoned simplifying hypotheses, the MV plant has been simulated using EMTDC-PSCAD, software commonly used for the simulation of earth power systems. The main outcome is the high accordance of the results of a simulated measurement of Total Harmonic Distortion of Voltage (THDv) on the vessel main MV busbar, with the experimental data taken from real measurements carried out on board. This validates the proposed approach for this kind of design problem.
