The relevance of this study is justified by the introduction of digital transformers to modern electrical substations and the need to create relevant digital systems for the automatics relay protection. The article discusses the basic principles of automatics relay protection of the digital electrical substations. The authors examine the problems of its implementation with the use of embedded systems based on domestic computing systems of the Elbrus family with the support of a protected mode of program execution. They suggest an architecture of the user program for managing the automatics relay protection system at a digital substation. Based on the architecture of user tasks and the requirements of the industrial standard, the authors form the restrictions imposed on the software and hardware of the computing systems used in embedded systems in the industry. This paper presents some results of the protected mode in real problems of automatics relay protection at digital substations. The study demonstrates the advantage of using protected mode in creating programs that control industrial facilities. The authors consider the effect of protected mode on the performance and fault tolerance of the target system.
