The present invention relates to a method for controlling a wind generator, more specifically, to a method for controlling output of a wind generator which comprises an output increasing step of adding output of a wind generator to an effective power value proportional to kinetic energy stored in the wind generator at accident occurrence timing in case of an accident to increase output wherein the output increasing step calculates an output increasing amount by using mechanical input and an electrical output curve at corresponding wind speed of the wind generator. 본 발명은 풍력발전기를 제어하기 위한 방법에 관한 것으로 보다 상세하게는 사고 발생 시, 풍력발전기의 출력을 사고 발생 시점에 풍력발전기에 저장된 운동에너지에 비례하는 유효 전력 값을 더하여 증가시키는 출력 증가 단계를 포함하고, 출력 증가 단계는 풍력발전기의 해당 풍속에서 기계적입력과 전기적출력곡선을 이용하여 출력증가량을 산출하는 것을 특징으로 하는 풍력발전기의 출력 제어 방법 방법에 관한 것이다.
