Analyzing Simulink Modeling Capabilities of Real Technological Disruption in Power System Section

Modern PSP systems can record precise instrument transformer readings during failures. This helps analyze the operation of algorithms and the correct trigger settings for specific protection systems and automations. However, if the settings are incorrect, the equipment can undergo electromechanical and thermal impacts causing its damage and failure. Using the simulation modeling method can help prevent such situations by the better adjustment of settings. In this research, the authors analyzed the applicability of the developed simulation model for a transit 110 kV power line (powered from 220 kV substation buses) with a set of protection systems installed. The applicability was analyzed in comparison with the AURA data at the moment of the emergency shutdown of a 110 kV power line located in the Voronezh Oblast.
