Abstract-India has a vast source of renewable energy sector, in that wind energy contributes a major role. From the source of wind energy we cannot be able to attain maximum generation of power due to the operation wind turbine under European atmospheric condition. So there should be need to optimization of blade profiles which should be suited for low wind condition(India) that leads to increase in coefficient of performance. In this work 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.

The horizontal axis wind turbine (HAWT) blades rotation in the steady wind flow is considered. We discuss the problem of determining the blade twist which could guarantee the maximum value of the power coefficient. We define the blade twist as the technological turn of sections of blade around its axis. This turn changes the effective pitch angle of turbine blade along its length. For description of aerodynamic load upon the blades we used the quasi-steady approach. Air velocities of centers of pressure of blade sections are represented when taking into account components induced by flow and vortex. We reduced the functional maximization problem to find the maximum of non-dimensional function. This function is given by Riemann integral depending on section pitch angle and tip speed ratio. We suggested the algorithm for solving the problem under consideration for a given blade shape.

The present study explores the performance of the small horizontal axis wind turbine. NACA-44 profile for wind Education Kit at different wind velocity range of (3.5 to 5.5 m/s) is used to achieve this study. The effects of changing the pitch angles (10°, 30°, and 45°) of the blade on the power performance of small wind turbine rotor models were investigated experimentally. (3, 4 and 6 blades) have been used to compare the results at each pitch angle for the different wind velocity. A computer program code was built to simulate the mathematical model. The axial induction factor indicates the degree to which the wind velocity at the upstream of the rotor is slowed down by the turbine; the power coefficient and the thrust coefficient for a range of axial induction factor have been evaluated and compared for different blades pitch angles. The maximum power coefficient obtained is about 0.51 occurs at 10° pitch angle for the 3 blades. Furthermore, it has been shown that the increase of wind velocity at a certain point will drop the overall efficiency down.
