【 摘 要 】

India has a vast source of renewable energy sector, in that wind energy contributes a major role. The required source of wind energy in India cannot be able to attain maximum generation due to the operation wind turbine under European atmospheric condition. There is a need to optimize blade profiles which should be suited for low wind condition (India) that leads to increase in coefficient of performance. The present works varying of blade profiles taken in root, mid and tip section of blades are evaluated. According to properties of blade element momentum theory (BEMT) and computational work are developed for getting power curves for varying parameters such as tip speed ratio, lift and drag coefficient and main parameters like chord and twist distribution.
