Effect of Wind Speed and Blade Deflection Angle on the Output Power of Horizontal-Axis Wind Turbines

Abstract

This study is aimed to optimize the conversion of kinetic wind energy into electrical energy. Wind energy is a sustainable energy that is preferred to generate electricity for its low generation cost and low CO2 emissions. The considerations of physical principles of a horizontal axis wind turbine were involved in the study. Controlling of the blade angle deviation and the turbine rotation direction was also considered. For this purpose, a complete wind turbine system was setup by using the computerized simulation software (PSCAD). The system was running at five different cases with different wind speeds and different angles of the blade. The system was successfully generating a maximum output power from the wind turbine based on the changing of the deflection angle of the blade. Also the system would shut down if there were no matching between the wind speed and its direction with the angle of the blade.
