Abstract

Objective It is difficult to carry out effective online monitoring and condition evaluation using traditional modeling and analysis methods. Therefore, it is imperative to research an accurate and effective virtual real mapping method for the whole life cycle of a marine condensate feed water system.
Methods On the basis of multi-domain modeling, this paper combines the mechanism model with multi-source data, uses the multi-domain physical modeling language Modelica/MWorks system simulation platform to build a digital twin model of the condensate feed water system, and integrates online and offline data, numerical calculation, simulation analysis and other methods to evaluate the operating state characteristics of the condensate feed water system.
Result The established model can analyze the dynamic characteristics of the condensate feed water system under all working conditions with a static analysis error lower than 2%. The dynamic response trend is consistent with the actual operation.
Conclusion This study shows that the proposed method can realize virtual real mapping between the physical entity and the digital twin model of the marine condensate feed water system, thereby laying a foundation for the health management of shipborne thermal equipment.
