전기철도 운행 중 차량 부하 변화에 따른 고조파 발생에 관한 분석

Recently, TTX(Tilting Train eXpress) has operated test. Electric railways, including the TTX, have electric problems(harmonic etc) that could bring about serious accidents.. Thus, TTX's electrical problems also need leading studies because the new Korean TTX will operate earnestly in 2012. In this paper, electrical signals in TTX operation were detected to analyze electrical harmonic. The electrical harmonics considered operation modes triparted(coasting, acceleration, braking) were analysed and evaluated.
