본문

본 논문은 모듈형 멀티레벨 컨버터를 이용한 특고압 직류 배전용 지능형 변압기의 운용을 위한 제어 기법을 제안한다. 기존의 저주파 변압기는 부피와 무게가 매우 크며 효율이 낮다는 단점을 갖는다. 이에 반해 다수의 IGBT를 사용하는 지능형 변압기는 시스템의 부피를 저감할 수 있으며 고효율 운영이 가능하다. 또한, 직류 배전 계통의 단락 사고가 발생하였을 때 직류 차단기의 역할이 가능하다. 본 논문에서는 지능형 변압기의 토폴로지, 변조 방법을 제시하고, 스위칭 및 출력 특성을 분석한다. 시뮬레이션을 통해 제안하는 지능형 변압기 운용 제어 기법의 타당성을 확인한다.
