description: This work is devoted to the study of abnormal modes of operation of the local area network of a digital substation during the transfer of information between intelligent electronic devices and methods for diagnosing these modes. The paper presents a project of relay protection and automation of a 110/10 kV substation, based on RPA microprocessor terminals manufactured by LLC NPP Â«EKRAÂ». The description of the main circuit and the main electrical equipment of the substation is given. The calculation of short-circuit currents was performed, based on the results of which the settings of the main and backup protections were calculated, and the calculation of traffic in the local area network. The analysis of network distortions that occur during the transmission of information, as well as the "Information Storm" mode, has been carried out. A description of the software and hardware tools for diagnosing the local computer network of a digital substation in accordance with IEC 61850 is given. Methods for testing and simulating abnormal network operation modes are considered. The scheme of connection of relay protection and automation equipment, the block diagram of the LAN are presented.
