Electromagnetic Transients in Medium Voltage Networks with Realistic Load Modeling and their Impact on Power Quality

This paper presents the impacts of various electromagnetic disturbances on the quality of energy delivered to end consumers through simulations in EMTP software. It utilizes both linear load models and models based on EMT components within a realistic distribution system in Brasilia, Brazil. The obtained results are analyzed from the perspective of the ITIC curve to classify which electromagnetic disturbances are capable of producing overvoltages with sufficient amplitude and duration to potentially cause damage to electronic equipment. This aims to characterize the existence of causality relationship, defined
$as$
the condition for the electric utility's compensation to the end consumer due to equipment damage. Furthermore, it emphasizes the need for realistic load modeling based on EMT components in the study of overvoltages that may cause electrical damage to low-voltage consumer equipment.
