Investigation of Ship's Power System with Powerful Electrical Propulsion Drive

The power of ship's electric systems grows constantly caused by the growing number of electric consumers. Especially powerful are the ship's power stations on ships with electric propulsion. These are the passenger ships, container vessels, gas and marine vessels. The power of propulsion electric motors of this ships reaches several tens of megawatts. The control of propulsion electric motors is done using electronic converters. In this article, it is proposed mathematical model of ship's power system containing 4 diesel generators and azimuttic propulsion electrical system. With the model are investigated the normal and emergency operating modes of propulsion electric system. Conclusions are drawn for the control and protection of ship's power system.
