고속철도 전철변전소 피크전력 저감을 위한 기술개발 연구

These high-speed railways is increased the peak power due to load fluctuation occurrence in accordance with the operating status of the train, and it causes the energy costs increase. In addition, harmonic generated from the traction motor of high-speed railways, and it will have adverse effects such as communication induction failure of power equipment, over-current and malfunction. In this study, we introduce a research development results of active harmonic filter and peak power reduction device that has been developed for harmonic management and peak power reduction.
