Abstract:
Traditionally, electric shipboard systems are operated radially and shipboard propulsion are not used to serve vital loads. In order to increase power management flexibility and shipboard system survivability, the US Navy is currently developing Integrated Power Systems (IPS) that integrate the propulsion system as part of the overall electric power generation and distribution system. New control strategies are being developed to allow for fast reconfiguration under emergencies. In order to test new controller designs, it is useful to have a model of these power systems which allows for simulation of salient system modes under multiple operating scenarios.
In this thesis, a Matlab/Simulink-based model of a notional version of the DDG 1000 electrical distribution system was developed. This model allows for simulation of loss of generation, line damage and reconfiguration for all desired control strategies. The proposed mathematical models of components in this system are presented including assumptions and limitations. Simulation models and results are provided that demonstrate that the model performs as designed and that the system is able to accommodate a proposed control design. Simulation results of various fault scenarios demonstrate the effectiveness of the designed controller.
