본문

영구자석형 동기발전기(PMSG)를 이용한 풍력 발전 시스템 의 전력변환장치는 계통과 발전기를 직접 연결하므로 전체 시 스템의 정격을 고려하여 스위치나 필터의 용량을 선정해야한 다. 이러한 스위치나 필터의 용량을 줄이기 위해 전력변환부는 N개의 병렬로 구성하며, 스위칭에 의한 고조파를 효과적으로 줄이기 위해서는 Carrier Phase Shifted 스위칭 기법을 사용한 다. 하지만 병렬운전으로 전력변환부는 적은 기전력의 차이에 도 영상전류에 의한 순환전류가 발생하여 반도체 스위치에 악 영향을 미친다. 본 논문에서는 영구자석형 동기발전기를 이용 한 풍력발전기의 병렬운전 시스템을 구성하고 병렬운전으로 인 해 발생할 수 있는 순환전류를 저감하기위해 중성점 전압을 이 용한 영상전류 보상 기법을 제안한다. 시뮬레이션을 통해 제안 하는 기법의 타당성을 검증한다
