Digital twin technical system for marine power systems

  Objectives  Aiming at application of digital twin technology to marine power system (MPS), this paper investigates technology route being adopted to implement digital twin in the design process of MPS, which it exhibit features of high integration and full life-cycle development.

  Methods  A research of digital twin technical system is done in accordance with the characteristics of MPS development, making use of a set of advantages of digital twin, such as virtual reality fusion and real-time interaction, iterative operation and optimization, and all-element, all-process data-driven,etc.

  Results  The structures of digital twin technology top-level system framework, platform construction system, key technology system and digital twin model construction system are constructed.

  Conclusions  The results of this study can provide quantitative support for the demonstration applications and practices of MPSs based on digital twin technology systems.
