MATLAB AbstractWind power to get more energy for the purpose, can hope to achieve is eligible forthe maximum economic benefits. The method can achieve the greatest benefit iseligible under varying wind speed to ensure fans can get the maximum power. In thepursuit of maximum power at the same time, a variety of factors damage the fan alsocan not be ignored.Absolute majority of cases the designer wants wind turbines in the case of constanttorque operation work, or change in the torque acting on the rotor is as small aspossible. But as a process of wind energy, wind velocity magnitude, and directionoften changes, wind speed or direction of the mutation will produce a torque on therotor mutation, this mutation causes the moment the wind wheel vibration, increaseblade loading, severe even cause leaf damage. Also, if the power mutation causes amutation torque, long run will harm the fan, affect their life. Thus, the torque controlsystem of the fan blade load optimization, and the protection of the entire windturbine play an important role.In this thesis, the torque of the wind turbine blade loading hazards, permanentmagnet synchronous generator, for example, designed a direct torque control system.First, several main types and technical characteristics of the wind made a briefintroduction, then presents a direct torque control technology, the establishment ofpermanent magnet synchronous generator Direct Torque Control System Based onthis, the last use of MATLAB / Simulink simulation tools to build simulation model ofthe system described above, and no fan control system were compared by analysis andsimulation results prove torque control technology can solve the power instability,large torque ripple and other issues, and then complete the wind turbine loadoptimization.
