Modeling The Blades And Analyzing The Character In The Running Wind Turbine Generator System

Based on wind turbine aerodynamic characteristics, this paper analyzes two modeling methods for wind energy absorbs of trubine. Compared the methods, the method based on the theory of the blade's chip is choosed and modeled with MATLAB. The model can be used by all kinds of wind turbine, and the torque of wind turbine is obtained when the character's dates of wind turbine were given. Through modeling the wind velocity, the torque when the wind turbine was running is outputted, and this is useful to model the running process of the wind turbine. Through setting the wind velocity, the rotate speed and the blade angle, curves which shows the character of wind turbine is obtained, and is a useful guidance for analyzing the character of wind turbine and making the corresponding control method.
