Design and Simulation of Pitch- regulated Mechanism of Wind Turbine Based on Simulink

The theory of blade element momentum is used to determine the pitch angle change under working conditions,rather than empirical formula. The control accuracy was improved in theory,and based on this,pitch- regulated mechanism of wind turbine was designed. Through simulation,the correctness of the design was veryfied and the drive displacement,velocity and acceleration are achieved under the condition of uniform rotation pitch angle.
