description: This work is dedicated to the study of methods for automating the commissioning and diagnosis of differential-phase protection for power lines. The following tasks were addressed during the study: 1. Studying the basic technical solutions and general information on the HPL protection project. 2. Reviewing methods for constructing DPP, industrial protection samples. 3. Developing and testing a digital twin of an HPL with DPP using the Matlab/Simulink software package. 4. Developing automated testing and diagnosis programs for DPP. This work examined differential-phase protection for power lines. Analyses were conducted on the operation, commissioning, and maintenance of DPP. The main errors when using protection were identified, statistics of operation were processed, and a classification of protection errors was collected. Using the Matlab/Simulink software package, a digital twin of the HPL with DPP was developed and tested. As a result of this work, a program based on the use of the digital twin of the Matlab/Simulink software package and calculations of fault waveform was developed. The developed program allows for prompt diagnosis and commissioning of the DPP device, as well as rapid detection of potential problems and emergency situations. It was possible to significantly improve the efficiency and reliability of the DPP device, as well as reduce the time required for diagnosis and commissioning.
