The Control Algorithm And Simulation In The Design Of Yaw Control-small Wind Turbine

The side-off parameters of the small side-off wind turbine affect the efficiency and safety of the wind turbine.However,the side-off parameters have been lack of more authoritative verification.Bladed software is a relatively authoritative software in the wind power industry,but the software does not set the yaw speed regulation module for small wind turbines.Therefore,to verify the yaw parameters in the Bladed software,external controller should be introduced.This subject is to study the yaw parameters of 10 KW small permanent magnet direct-drive side-deflection wind turbines.The main contents include: first,the determination of the yaw parameters,which are based on the momentum leaf element theory and some important aerodynamic theories;Then,according to the correlation between the yaw parameters,the specific values of the yaw parameters are summarized.The second is to verify the accuracy of parameters based on GH_Bladed.Firstly,a 10 KW wind turbine model is established and programmed on visual c++ 6.0.The program content is to introduce the yaw parameters into the Bladed wind turbine model.The specific action is to add a stern rudder module and give the wind turbine model a yaw instruction.Then,the simulation was carried out according to the parameters to observe the output load of the wind turbine,including the output power and output torque,as well as the value of the wind energy utilization coefficient at different wind speeds.By observing the output of the wind turbine,it can be seen that under different wind speeds,the fan can operate normally after side deviation,which proves that the selected side deviation parameters are accurate and effective from the side.
