Abstract

This paper shows the comparison of operating characteristics between squirrel cage induction generator and DFIG(Double Fed Induction Generator). Because squirrel cage induction generator consume the reactive power due to magnetizing reactance, the capacitor is need to compensate the reactive power. Otherwise, two back-to-back PWM voltage-fed inverters connected between the stator and the rotor allow sub/super synchronous operation with low distortion currents. In this paper, the response characteristics of squirrel cage induction generator and DFIG, were analyzed and investigated using PSCAD/EMTDC.

본 논문은 이중여자권선을 갖는 권선형 유도발전기와 농형유도발전기사이의 운전특성비교를 보여준다. 농형유도발 전기는 자화리액턴스에 의한 무효전력소비 때문에, 역률을 보상하기 위한 콘덴서를 필요로 하나, DFIG는 회전자에 Back-To Back컨버터를 가지고 있기 때문에 저속/고속에서 유도발전기가 운전이 가능하다. 본 논문에서는 PSCAD/TMTDC를 이용하여 농형유도기와 DFIG의 응답특성이 분석되었다.
