Abstract

Abstract:

One of the most workable techniques used in wind turbine blades designs is the Blade Element Momentum (BEM) theory. In this work, BEM technique is used to assess the power and certification of small horizontal axis wind turbines (HAWTs) with 3m blade length and 2 kW power rating. The primary goal to accomplish in the present work is to evaluate the performance of the BEM method in predicting the aerodynamic behavior of small scale turbines through comparison with the experimental measurements. Interest attention is paid to the dependent factors which include lift and drag forces, blade pitch angles, tip speed ratio, and power coefficient. Analysis and modeling of the blade geometry and necessary operation parameters are modeled to improve efficiency using relevant real life software. The findings indicate how the BEM method performs in modeling the aerodynamics of staking axis and tiny turbines and where improvements to blade design in low wind speed zone is feasible. This work also makes a contribution to finding solutions for efficient and affordable small wind turbines to help foster the use of renewable energy solutions in distributed power generation systems.
