Modeling of Electromagnetic and Thermal Processes at System with Resistive Grounding of the Transformer Neutral

Abstract

The application of PSCAD (Power Systems Computer Aided Design) and Comsol Multiphysics software complexes for simulation, calculation and visual representation of thermal and electromagnetic processes occurring in a single-phase ground fault with an intermittent arc in medium-voltage networks with resistive grounding of neutral is considered in the article. The simulation was carried out to predict the behavior of a real power supply system and optimize conditions functioning of the developed technical solution.
