Study on Nacelle Cover Shape Improvement of 250 KW Wind Turbine

Nacelle cover is very important at the wind turbine because nacelle includes mechanical and electronical parts. So nacelle cover must be hard shape which can withstand the external force. This study is to determine shape of wind turbine about influence by wind. It has a CFD analysis using analysis software 'ansys workbench' to determine shape of the current nacelle cover of 250KW wind turbine, changed the shape of the nacelle cover, streamlined shape nacelle cover. When wind passes the nacelle cover, because of shape, this study finds out difference to influence of wind so determine shape of nacelle cover Keywords - Wind Turbine , Nacelle Cover, Computational Fluid Dynamics(CFD)
