Abstract

In this paper, a maximum output power control of stand-alone cage-type induction generator systems for wind power generation is proposed. The induction generator is operated in a vector-controlled mode, which is excited with d-axis current and of which torque is controlled with q-axis current. The generator speed is controlled by this torque, along which speed the generator produces the maximum output power. The generated power charges the battery bank for energy storage through an ac/dc PWM converter. The proposed scheme has been verified for the wind turbine simulator system which consists of M-G set.

본 논문에서는 농형유도발전기를 이용한 독립형 풍력발전시스템의 최대전력 추종제어기법을 제안한다. 농형 유도발전기는 벡터제어 방식으로 동작되는데 d-축 전류에 의해 여자가 제어되고 q-측 전류에 토크가 제어된다. 이 토크제어에 의해 발전기는 풍속의 변화에 따라 최대전력을 발생하도록 가변속 제어된다. 발전된 전력은 ac/dc PWM 컨버터에 의해 직류 출력단 배터리뱅크로 충전된다. 제안된 기법은 M-G세트로 구성된 터빈시뮬레이터를 이용하여 실험적으로 검증된다.
