Digital Twins for Process Optimization and Optimal Maintenance

Work package "Digital Twin"

In this project's work package XRG, who is a developer of the succesful ClaRa+ model library, will elaborate general methods to derive numerical efficient digital twins from physically described power plant processes and use cases.


Digital twins for power plant processes


This future workflow is going to enable a data-driven calibration of pysical models and the replacement of model parts through said models. Afterwards the workflow will be integrated into ClaRa+ Library allowing a combination of physical and surrogate models.



The following german institutions are partnering in this joined project:
