Intelligent pitch angle control scheme for variable speed wind generator systems

The goal of this paper is to design a wind turbine generator operated under variable speed with intelligent pitch angle control capability under variable wind conditions. The control scheme for the variable speed wind turbines has been discussed and analysed using wind turbines driven by the permanent magnet generators connected to the grid. Main strategies of conventional control and intelligent control using fuzzy logic have been explained and compared to each other. Simulated output variables of voltage, current and power are also presented in this paper for various values of wind speed.
