In this paper, a wind turbine model for wind energy conversion system study is presented. The turbine static characteristics are modeled using the relation between the turbine power versus the wind speed and the blade pitch angle. The dynamic characteristics of the wind turbine are modeled through a 2-mass oscillating system, representing the mechanical coupling of the turbine and the generator. The turbine performance is subjected to a real wind speed pattern by modeling the wind speed as a sum of harmonics with wide ranges of frequency. The turbine model includes the effect of the tower shadow and wind shear. A pitch angle controller is designed to protect the coupled generator by limiting the turbine output power to the rated value. Simulation results are provided to verify the wind turbine simulator performance.read more
