| Abstract |
This paper analyses from different points of view the electrical drives for ship propulsion systems. In fact there are many possibilities to accomplish electric propulsion. However the most modem and correspondingly latest installations are based on fixed generator speed and motor speed control. Marine applications are mainly based on AC electrical drives equipped with power electronic systems (current source inverters or cycloconverters or voltage source inverters). It is a common assumption for naval engineers that if electrical propulsion is feasible for a ship, it
is feasible whatever drive concept is selected. But at the same time several configurations are proposed whose aims
are to comply the following main design criteria: torque and speed performances; redundancy; investment cost;
available space and shape (weight/length) of the propulsion motor room. This paper will perform a comparative analysis of the basic, redundant innovative configurations in terms of the above defined items and the impact of electric power supply and noise-vibrations. The requirements and the guidelines for the power converters design will be also outlined. |
