Eletrônica de potência
Tração ferroviária
Abstract in Portuguese
O objetivo deste trabalho é realizar medições de distorção de tensão e corrente na entrada de subestações que alimentam sistemas ferroviários e verificar se estas atendem às normas IEEE - 519:1992 e IEC 61000-3-6:2008. Foram realizadas medições durante uma semana nas subestações retificadoras Tietê e Jaraguá, ambas da CPTM. Os resultados das medições foram comparados com simulações computacionais baseadas em um modelo simplificado do sistema de alimentação.

Abstract in English
This study reports an experimental assessment of current and voltage distortion at the ac side of railway power supply installations and their compliance with the IEEE-519: 1992 and IEC 61000-3-6: 2008 standards. All experimental measurements were conducted using a commercially available power quality analyzer installed during a week at the CPTM rectifier substations of Tietê and Jaraguá. A simplified model was applied to computer simulations in order to calibrate the model through the comparison with experimental results.
