A model has been built to link a shipboard electrical power system, and its consequent heat loads, with an in-house thermal simulation framework specifically created to address issues of shipboard thermal management in a dynamic, system-level sense. An electric power model was created to capture the transient nature of heat dissipation as a function of the dynamic nature of power converter modules in an electrical, power distribution network. The power network was then mated with a thermal resistive network that links the heat loads to the thermal management network. The resulting network is dynamic in nature and captures the essential transient characteristics of heat flow and energy storage while accommodating the greatly disparate time scales inherent to thermal and electrical networks.
