초록

풍력발전은 넓은 범위의 속도제어를 요구하며, 권선형 유도발전기를 이용한 DFIG시스템을 이러한목적에 잘 부합한다. 동기속도 이상의 영역에서 풍속에 의한 원동기 속도와 증가에 불구하고 회전자 여자 주파수를 슬립주파수와 다르게 인가하여 DFIG의 속도와 출력 제얼르 다루고 있다. 속도제어와 동작점 이동의 해석을 위하여 토크시뮬레이션을 하였고, 회전자 여자주파수와 전압제어에 의해 출력이 정격값 이하의 안정된 영역에서 제어될 수 있음을 고찰하였다.

Wide operating range and speed control is needed for wind power generating and a Doubly Fed Induction Generator(DFlG) has good adaptivity for that purpose. Ths paper investigates speed and output stator power control using a grid connected to a DFlG in super-synchronous speed regions, by control of both magnitude and frequency of the voltage fed to the rotor. For the speed control analysis, torque simulation is perforrred whereby the different slip between qJernting rmtor driving frequency and synchronous frequency of M-G system awlied. To keep the output rating of the generator, the exciting frequency and voltage attenuation are arolied.rolied.
