ADAMOU Under the title:

“Efficiency-Based Digital Twin Implementation For In-Service Induction Motors In Industry 4.0”

 

Abstract 

The thesis is situated within the context of Industry 4.0, where emerging technologies establish standards for decision-making, a critical aspect of industrial sectors. Key innovations, including Digital Twins, are vital to this industrial revolution, with artificial intelligence acting as a powerful catalyst for performance enhancement. Energy efficiency in facilities is one of the foundational pillars of Industry 4.0. Achieving Industry 4.0 involves either constructing or replacing existing industrial equipment to meet these new standards or developing adaptive methods to transform current systems into compliant ones. To address this need, our thesis proposes the creation of an energy efficiency-based Digital Twin specifically designed for in-service Induction Motors, which represent approximately 70% of industrial electrical energy consumption among all electrical machines. This proposed Digital Twin serves as an adaptive platform for these motors, emphasizing the transformative potential of Industry 4.0. It predicts the efficiency and losses associated with the motors and enables fault detection, making it particularly suitable for predictive maintenance which contribute to energy saving. For instance, a mere 1% improvement in the operational efficiency of induction motors could result in saving 105 TWh in the industrial sector. By implementing this solution, we aim to significantly enhance energy efficiency and elevate overall industrial performance.

Keywords:

Induction Motors, Electrical equivalent circuit, Adaptive-Neuro-Fuzzy inference system, Energy efficiency, Losses, Digital twin, Digital Shadow, Industry 4.0.

Abstract:

This thesis is situated within the framework of Industry 4.0, where emerging technologies redefine decision-making standards, which is a crucial aspect of industrial sectors. Among major innovations, digital twins play an essential role in this industrial revolution, while artificial intelligence acts as a powerful catalyst for performance improvement. Energy efficiency in facilities is one of the fundamental pillars of Industry 4.0. To meet the goals of this new era, it is necessary either to build or replace existing industrial equipment to comply with these new standards, or to develop adaptive approaches to transform current systems into compliant systems adapted to this revolution. To meet this need, our thesis proposes the creation of a digital twin focused on energy efficiency, specially designed for in-service induction motors, which represent approximately 70% of the electrical energy consumption of electric machines in the industrial sector. This digital twin serves as an adaptive platform for these motors, thus illustrating the transformative potential of Industry 4.0. It enables the prediction of functional efficiency and the losses associated with the motors, while facilitating the detection of motor faults, making it a tool particularly suited to predictive maintenance, thereby contributing to energy savings. For example, an improvement of only 1% in the operational efficiency of induction motors could generate a saving of 105 TWh in the industrial sector. By implementing this solution, we aim to significantly improve energy efficiency and strengthen the overall performance of industry.
