A Novel Direct Control Procedure for an Interior Permanent Magnet Synchronous Generator Based Wind Turbine with Variable Speed

This paper proposes a novel direct control policy for an interior permanent magnet synchronous generator-based wind turbine with variable speed. In this system, the condition of the incessant rotor place is eliminated as all the calculation is finished in the stator orientation casing. This method possesses reward such as smaller constraint reliance and abridged digit of controller compare among the conventional indirect vector control method. The direct control design is simpler and can eradicate some of the drawback of established indirect vector control design. The projected control method is implemented in MATLAB Power Systems and the outcome illustrate that the controller be capable of function under stable and changeable wind speed. Lastly a sensor less velocity estimator is in implementation which enables the wind turbine to drive without the perfunctory speed sensor. The simulation and investigational consequences for the sensor less speed estimator are obtainable
