    Abstract

    To meet the power shortage in the country and make it more cost effective with India specific context more emphasis has been given to generate power from wind from low wind to moderate wind speeds. To take advantage of latest technological advancement in this field and to evaluate proper methodologies, design data generation and to put a solid foundation for future utility CWET had taken a lead to sponsor an project to NAL. Presently National Aerospace Laboratory with a wide variety of expertise in the related areas have embarked on providing a reliable, state of art technology and manufacturing support as well as training to their personnel for private companies and NAL have made MOU for the development of wind turbine blades using FRP materials and the same will be evaluated using private wind farm platforms. Geometrical data generation, modeling, design of mechanical and structural systems and its analysis, design of electrical and control systems and its analysis, fabrication of blades, field measurement, data reduction, use of commercially available and in-house developed Computational tools like FLUENT, IMPRANS for aerodynamic analysis and BLADED for Windows for power computations had been carried out by different groups of NAL. This report gives methodologies, assessment of wind turbines and validation of aerodynamic performances for a specific purpose to meet the CWET program.
