Abstract

This paper proposes a dc power regenerating systems, which can generate the excessive dc power from dc bus line to ac supply in substations for traction system The proposed regeneration inverter system for dc traction can be used as both an inverter and an active power filter(APF). As an 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. From the viewpoint of both power capacity and switching losses, the system is designed on the basis of three phase PWM inverters and composed of parallel inverters, output transformers, and an LCL filter.

본 논문에서는 전철시스템의 변전소에서 직류모선에 발생하는 잉여분의 직류전력을 교류전원 측으로 회생시킬 수 있는 직류전력 회생시스템을 제안한다. 제안된 직류 전철용 회생인버터 시스템은 인버터와 능동전력필터로 사용할 수 있다. 회생인버터 모드에서는 전철의 감속에 의해 회생되는 에너지를 재사용 할 수 있으며, 능동전력필터 모드에서는 변전소의 정류기에 의해 발생되는 고조파 왜곡을 보상하기 위해 사용할 수 있다. 전력용량과 스위칭 손실을 고려하여 시스템은 3상 PWM 인버터를 기반으로 설계되며 병렬인버터, 출력변압기와LCL필터로 구성된다.
