High rates of oil and gas industry development, their production volumes increase as well as the remoteness of the industry developing facilities inevitably cause an increase of energy consumption and the complexity of energy systems. The main consumer of electricity of these facilities are electric motors of drive devices of compressors, pumps, power outages of which can lead to large economic losses. The authors of the article consider the problem of testing the relay protection of an electric motor. The digital twin is a developed set of digital protection algorithms that complies with IEC 61850 standards and allows identifying problems of electric motors digital protection prior their operation in standard mode, automating the selection of setpoints and evaluating the protection response to various operating modes without extreme testing of a real machine. The study of the proposed digital model of electric motor protection has shown an increase of the sensitivity and reliability of digital relay protection thus minimizing the risks associated with erroneous actions of personnel.
