초록

This paper proposed 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 include to ac current source. The regenerative inverter is operated as two modes. As a regeneration inverter mode, it can recycle regenerative energy caused by decelerating tractions and as an active power filter mode, it can compensate for harmonic distortion produced by the rectifier substation. In the paper, a regeneration inverter used PWM DC/AC converter algorism. And an active power filter used p-q theory. The simulation was composed as a prototype model[3kW]. Simulation results show that two algorism can be used to real model[100kW]. Finally, the inverter was successfully operated as regeneration mode."
