Development of a Laboratory-Practical Complex for Modeling Power Supply Systems

The article presents an approach to the creation of a laboratory complex for research and practical work using digital substations, and as part of the research, the problem of increasing the reliability of digital substations by redundant control elements is solved equally with the power parts of the system. The equipment was tested and theories were tested regarding the behavior of power supply system's together with the relay protection system in an emergency on the basis of a laboratory complex. Information is given about possible experiments in the developed laboratory environment and the principles of functioning of the laboratory system in the conditions of student learning.
