Aerodynamic model of wind turbine considering yaw error

In order to evaluate the influence of the yaw error on wind farm active output, blade element theory is used on aerodynamic characteristics modeling of horizontal axis wind turbine. This paper is based on the analysis of blade element force. Considering the effects of wind direction error, eddy current and gas compressibility, the model is realized in MATLAB/Simulink. The system model of wind turbine is built up by joint other subsystems, using 1.5MW DFIG as an example, the simulation is taken in with or without yaw error and under or above the rated operating condition, the simulation result verified the correctness of model. The study also has reference value on the wind farm simulation and controller design.
