Mathematical Model of a Ship Power System with DC Power Distribution System

The power of the energy systems of modern ships and marine offshore platforms is increasing. In order to achieve greater reliability and ensure sustainable operation of the ship's power plant, a direct current distribution network is used. Such ship energy systems have a number of advantages, but there are problems with the distribution of power between parallel gener-ators, with the quality of power on the AC and DC side. The article proposes a mathematical model of ship power system with DC power distribution system, containing DC and AC loads. With the help of the model, normal operating modes and transient modes caused by various disturbing disturbances are studied. The quality of AC and DC power is shown.
