Development of a digital twin of the control system test bench for digital instrument transformers

The presented work considers the option of implementing a digital twin of a test bench control system for digital instrument transformers using a universal SCADA system. The basis of the design of the test bench is a hydraulic servo drive using hydrostatic guides. Digital instrument transformers must have a service life of at least 25 years, a verification interval of 8 years or more. To achieve such high performance characteristics, a large number of tests are required for such products. In particular, to check the reliability of operation of this class of devices, it is necessary to conduct tests on a diagnostic vibration stand. The task of creating test benches based on a hydraulic servo drive using hydrostatic guides is an urgent scientific and technical task. The architecture of a digital twin of the test bench control system has been developed. To test the functionality of the application, a simulation of the operation of a digital twin of the control system of a test bench for digital instrument transformers was performed.
