THE PRACTICAL CYBERATTACK ON THE DATA TRANSMISSION CHANNEL OF THE DIGITAL SUBSTATION

Abstract

The development of information systems in the electric power complex has led to the emergence of problems ensuring cyber security. In order to assess the impact of different types of cyber-attacks on the stability of the digital substation, in this work two experimental attacks were made on the simulated data transmission channel. The features of the operation of electrical substations of the new generation, the technology of testing electrical substations with modern software product EDScout from OMICRON, allowing not only to evaluate data streams from technological devices, but also to emit them are shown. Based on the analysis of the results obtained, solutions to the indicated problem were proposed, with devices supporting the functions of checking the content of GOOSE messages.
