Electric propulsion for cruise liners has now become a standard owing to its several advantages. However propulsion drives have a large impact on the ship power system. This gives rise to the requirement for designers to understand in depth the effects of propulsion drives on the ship network in different operating conditions. For this purpose computer simulations have proved to be a very useful tool.In the paper a typical propulsion drive for an all-electric cruise liner is described and simulation results are shown. Owing to the model complexity, simulations turn out to be computationally quite heavy. For this reason a simplified model has been developed. Simulation results, from the ship network viewpoint, proved to be close to the detailed model ones.Index Terms-Marine vehicle propulsion, harmonic distortion, simulation software, Load Commutated Inverter (LCI), doublethree phase synchronous motor.

“…The subject of this investigation is mainly transient exponential functions. These occur for instance during LCI operation or in VRM drives (Colby et al, 1993;De Doncker et al, 1994;Hava et al, 1992). During LCI operation the currents are switched from one phase to the other phase (Figure 7).…”

The current distribution within multi strand windings is investigated for transient current and voltage supplies. The difference in losses between transient and sinusoidal waveforms is elaborated. Therefore, a wide range of frequencies as well as different kinds of transient waveforms has been investigated. The definition of the skin depth is no longer sufficient. A new parameter is required for transients, which is related to time. This parameter will be defined and called "skin time". A numerical method is developed based upon a finite element transient calculation. The method is applied to the winding as well as to the core. A comparison with measurements verifies the approach described.
