Abstract

The neural network pitch controller using changing rate of generator speed has been suggested in this paper to regulate wind turbine power above the rated wind speed. The changing rate of generator speed is used in the suggested pitch controller as well as the difference between the rated and current generator speed. Matlab/simulink has been used for simulations and it has been shown that the suggested pitch controller regulates generator speed as the rated speed of 122.9[rad/s].

본 논문에서는 정격풍속 이상에서 발전량을 일정하게 유지하기 위하여 회전속도의 변화율을 이용한 신경망 피치제어기가 제안되었다. 제안된 신경망 피치제어기는 발전기의 정격 회전속도와 현재 회전속도의 차이를 기본정보로 사용하고 추가적으로 발전기 회전속도의 변화율을 사용하였다. 시뮬레이션은 Matlab/simulink에서 수행되었으며, 시뮬레이션을 통해 제안된 피치제어기를 사용한 풍력발전기는 발전기의 정격 회전속도인 122.9[rad/s]로 잘 유지 되는 것을 확인하였다.
