Simulação de transitórios de transformadores de corrente utilizando Simscape (Matlab).

Abstract

This work has as objective the study and analysis of the behavior of transformer current transformers (CT). Current transformers are designed and designed to power metering, protection and control instruments in power grids. The most important point in the modeling of CT is a representation of the non-linear behavior of the magnetic core, which presents a saturable and hysteretic behavior. In order to analyze the behavior of the models, simulations were performed in Matlab through Simscape, which allows the construction of physical component models based on physical connections that integrate with the block diagrams and other modeling paradigms.
