Mathematical Model of a Ship Power System with Nonlinear Loads

The power of the energy systems of modern ships and marine offshore platforms is increasing. An increasing part of this power is converted with the help of power electronic converters. This trend is especially evident in ships with electrical propulsion. Converters are a non-linear load that creates problems with power quality and electromagnetic compatibility. The article proposes a mathematical model of a ship power system with a nonlinear load with a power comparable to the power of the generator. Different operating and emergency operating modes are simulated with the help of the model. Some of the obtained experimental results are presented. The obtained experimental results can be used to assess the quality of electricity, as well as the selection and design of tools to improve quality.
