Digital Twin Definition and Possible Applications

Certainly! A digital twin is a virtual representation of a real-world object such as an equipment or a more complex system., including multiple equipment These digital models accurately mirror the performance and behaviour of their physical counterparts, by showing the current state of real-world object such as an equipment or a more complex system, based on the collection of data in real time.

Such data collected will trigger the real-world object such as an equipment or a more complex system status based on predefined rules linked to the different running modes predicted her such as normal, faulty, out of order. faulty mode may have various steps before the total stop of a complex equipment.

Different steps to set up Digital twins:

1. Creation: The studied object (e.g., a wind turbine) is equipped with sensors that collect real-time data on various aspects (energy output, temperature, weather conditions, etc.).
2. Processing: The data from sensors is fed into a processing system, which actively updates the digital twin.
3. Simulation and Analysis: Using this digital model, various simulations can be run to analyse performance issues, identify inefficiencies, and explore potential enhancements.
4. Decision-Making: The ultimate goal is to gain valuable insights that can improve the original physical entity¹.
