Thermal Aspects of a Shipboard Integrated Electric Power System

8 pp.

Development and validation of a dynamic model focused on thermal aspects of the integrated propulsion system (IPS) on a notional all-electric ship (AES) is presented. This model serves as a baseline for investigation of thermal management technologies and architectures focused on identifying tradeoffs, improving system-level efficiency, and increasing the performance of an AES. The IPS model includes component models for gas turbine engines, synchronous generators, motor converters, propulsion motors, fixed-pitch propellers, and a ship hull. These component models are integrated into a system-level simulation and dynamic results for a ship-maneuver called a “crash-back” are presented. The resulting thermal-mechanical dynamics are discussed in depth.
