Maximum Power Point Tracker of Wind Energy Generation Systems

Abstract

Most variable speed wind turbines have pitch angle control mechanisms and one of their objectives is to extract maximum power from available wind speed. By adjusting pitch angles of wind turbine. In this research the use of pitch angle control for wind turbine equipped with self-exited induction generators (SEIGs) and power electronic converters is presented. To extract the maximum available power from the wind, the wind turbine is controlled using pitch angle control based on power signal feedback (PSF) method. The Maximum Power Point Tracking is achieved using two different approaches: The pitch angle control with PI-controller and the pitch angle control with PID-controller. In order to evaluate their performances, both control approaches were tested. The proposed wind generation system has been developed and tested using MATLAB/SIMULINK.
