The research presented in this thesis have been performed in 2012 at the Center for Advanced Power Systems (CAPS) of the Florida State University (FSU). Topic of research is the concept for the future All Electrical Ship (AES) of the U.S. Navy. Primary focus of this thesis is on a novel approach on modeling and simulation of electrical power supply system components using Scattering parameters ...

All-electric warships will require intelligent control strategies where the behavior of individual electric plant subsystems and devices can be modified to meet the changing needs of the ship to achieve the high level of performance required for survivability. A computational environment for simulating the performance of the electrical system and underlying controls is an essential part of the ...

In this paper, the main goal is to reduce the heave motion between a surface effect ship (SES) and a wind turbine in order to safely transfer equipment and person to SES. For this purpose, an LQR control system is designed to damp the vertical motion of the surface effect ship in critical sea states including high-frequency and high amplitude regular waves as well as high frequency irregular wa...

A large scale Simulink simulation model of the electrical power system of a ship is described. The model includes the major systems onboard, from prime movers to the actual loads, and incorporates several intermittent duty loads along with continuous duty loads. Three types of energy storage systems have been modeled: flywheels, batteries, and capacitors. Therefore, critical issues like stabili...

High-speed permanent magnet synchronous machines are of great interest in the applications where high utilization factor and e ciency are required. Depending on application, power requirements change from kilowatts to megawatts. To investigate power limits of high-speed machines, the present feasibility study focuses on a 20 megawatt (MW) electric drive for marine propulsion. However, in additi...
