Developing a validated real-time system-level thermal simulation for future all-electric ships

Abstract

This paper presents a method to perform real-time system-level shipboard thermal simulations. The modeling approach is described in detail as the method is applied to the cooling facilities of the CAPS 5 MW MV laboratory. The derived simulation is studied using standard model validation tools such as factor screening and uncertainty propagation. Error bounds of system response variables are compared to results from experiments on the CAPS cooling facilities published previously. The goal is to provide a first step in the development of real-time system-level thermal simulations suitable for future HIL simulations employed in the engineering of future all-electric ships. It is envisioned that these simulations will be useful for the development and testing of future system-level controls.
