description: This work is devoted to the study of emergency situations in direct current supply systems (DCSS), such as secondary switching networks connected to discrete inputs of microprocessor terminals of relay protection and the development of methods and algorithms for their detection. Problems that were solved in the course of work: 1. Physical study of emergency modes and phenomena in secondary switching networks. 2. Determination of methods for identifying emergency situations. 3. Development of an algorithm for determining an abnormal mode. 4. Integration of the algorithm into the model according to the IEC61850 standard. The work was fulfilled on the premises of PARMA LLC, where a significant part of the factual material was collected: the results of physical research, design, implementation, and testing of the operating model. Calculations were carried out describing the behavior of the system at the input of the microprocessor device under various states of the connected circuit. As a result, the main causes of emergencies in the DCSS were analyzed, the physical processes taking place were studied. A technique has been developed and an algorithm for detecting damage has been implemented. A method for inte-grating this algorithm into the IEC61850 data model is proposed.
