Abstract:
The main thrust of this paper is to present an efficient method for the pitch control of large scale wind turbines. After an investigation in wind turbine working regions, the “optimum” working levels are determined. A PID controller is designed based on the Ziegler – Nichols method. By appropriately tuning the controller gains, the proposed controller ensures achieving a rapid convergence to the extracted power set point with the minimum of fluctuations even in extreme wind conditions.
