 Abstract
The electric propulsion system requires more reliability and safety than the conventional propulsion system because any sudden changes of electric system would bring tremendous effects on the ship`s safety and propulsion. So it is very important to consider the potential transient effects. This paper discusses one of the worst electric accident. That is, one or two of generators are out of service in normal seagoing condition. And the appropriate measures are simulated in order to prevent the frequency decline that can bring the other generator`s tripping. In addition, the relation between the transient effects and the major factors(inertia of generator/motors, governor`s drooping characteristic and response speed) are also identified using the ETAP software.
