피치제어를 이용한 풍력발전시스템의 출력제어 = Power Control of Wind Turbine System Using Pitch Control

다국어 초록 (Multilingual Abstract)

This paper derives a modeling of a wind turbine and generator, and presents a power control algorithm for a full pitch-controlled wind turbine system. The design of a controller, in general, is Performed by linearizing the torque in the vicinity of a operating point assuming the tip speed ratio is constant. For power control, however, the tip speed ratio is no longer a constant. In this study, a reference pitch model is derived in terms of a wind speed, angular velocity, and pitch angle, which makes it possible to design a controller without linearizing the non-linear torque model of the blade. The validity of the algorithm is demonstrated with the results produced through sets of simulation.
