The article presents a complex of mathematical models of various classes and types and the results of their application in the description of the ship's electrical power system. The technique for determining the frequency characteristics of the propeller shaft system is shown. The ship electric power system is presented in the form of three levels, which include main engines, generators, control systems, power converters, and an electric propulsion system. It is shown how transient processes take place in the system when the load is turned on and external moments change
