Abstract:

Wind power generation has grown at an alarming rate in the past decade and will continue to do so as power electronic technology continues to advance. In this article, this study proposes to ensure an optimal mechanical power generated by a wind turbine in a chain for a wide range of winds. The amount of power output from a wind energy conversion system depends upon the accuracy with which the peak power points are tracked by the maximum power point tracking (MPPT) method searches an optimal operating point from the slope of the power rotational. This can be achieved by implementing a pitch control in order to tap maximum energy at wind speeds lower than rated wind speed, since the proposed method selects the operating mode according to the wind speed. If the wind speed exceeds its rated value, blades are controlled to limit the electrical power to its nominal value. Pitch angle control is the most common means for adjusting the aerodynamic torque of the wind turbine. A fractional pitch angle controller is developed in this paper. The fractional control strategy may reach the potential when the system contains strong non-linearity, especially when the wind turbulence is strong. The controller PI classical and PIα fractional in pitch angle control are compared with the wind gust disturbance. The simulation tests were conducted using MATLAB/Simulink.
