Use of Digital Twins for the Technological Equipment Condition Monitoring

The article describes the application of digital technology on the example of an AC electric motor in solving the problem of an electromechanical converter condition monitoring. In the course of creating mathematical and computer models, the existing methods of technological equipment condition monitoring were analyzed. Based on them, the optimal method was chosen for determining the current value of variables that are not easily accessible for direct measurement, followed by the construction of a complete mathematical and informational model. The paper describes the functional scheme of a digital twin of a three-phase electromechanical AC converter, and presents a process control system. The validity of the developed system for monitoring the condition of the equipment and the digital twin of the AC electric motor was confirmed by subsequent analysis of the compliance of the passport and received calculation data.
