Abstract |
This paper proposes a regeneration inverter system, which can regenerate the excessive power form dc bus line to ac source for traction system. The proposed regeneration inverter system for dc traction can reduce harmonics which are included to ac current source. The regeneration inverter is operated as two modes. In the regeneration inverter mode, it can recycle regenerative energy caused by decelerating tractions and in the active power filter mode, it can compensate harmonic distortion produced by the rectifier substation. In this paper, the regeneration inverter uses PWM DC/AC inverter algorithm and the active power filter uses p-q theory. From the informative simulation and experimental results, which are performed wiith a prototype rated 3.7[kw], it can expected that the proposed system can be effectively applied in the real traction system rated l00[㎾]. |
