Analysis of power distribution systems in marine vessels

Considering the importance of increasing the use of electrical systems on vessels, the assessment of power distribution systems in boats, especially in military vessels, has a special position. Although research on the characteristics of distribution systems has taken place, it is necessary to provide an appropriate analysis and to introduce the best system according to the conditions of use on vessels, especially military vessels. The most important point in choosing a three-phase distribution system in boats is how to connect the neutral point (neutral) of generators and transformers to the ground (boat body) and the use or non use of the neutral wire. The issues discussed in this regard are over voltage, stability of the functioning of boat vital systems, Error location detection, equipment safety and personnel safety. In this paper, while analyzing a variety of distribution systems, considering the importance of sustainability of vital systems functioning on boats, especially military vessels, the best system, "Three phase non-grounded power distribution system" is introduced.
