초록

본 논문은 정격속도 이상의 고속 영역에서 운전되는 스위치드 릴럭턴스 발전기의 효율 개선에 대하여 기술한다. 전류 형상은 발전기 손실에 큰 영향을 미치기 때문에 전류 모양을 조정함으로서 시스템 효율이 개선될 수 있다. 풍력 또는 소수력 발전과 같이 속도 범위가 넓은 경우 정격속도 이상에서도 최적의 전류 형상을 얻을 수 있도록 스위칭각 조정 방법이 제시된다. 제시된 방법을 검증하기 위해 실험장치가 구성되고, 이론의 가능성이 시뮬레이션과 실험결과에 의해 검증된다.

This paper describes about the efficiency improvement of switched reluctance generator (SRG) over the rated speed region. Since the current shape has a great influence on the loss of the machine, so the system efficiency can be improved by optimizing the current shape. In case the wide speed range application such as wind power and medium size hydraulic power generation, a method of switching angle control is suggested to obtain the wanted current shapes. In order to verify the method, the experimental platform is set up. The feasibility of the theory is verified by simulation and experimental results.
