Abstract : Among the different renewable energy sources, wind energy is currently making a significant contribution to power generation, and is emerging as a competitive option. Renewable energy is energy which comes from natural resources such as sunlight, wind, rain, tides, and geothermal heat, which are renewable (naturally replenished). About 16% of global final energy consumption comes from renewables. In this project, operational experience of site-specific data of different wind farms located at Muppandal region (Southern part of India) will be collect and interpret in detail. It is a fact that wind energy production shows a wide range of variation due to climatic and technical factors. The stoppage time of the Wind Turbine Generators (WTGs) reduced the real availability for approximately 20%. So it is essential to conduct a performance and reliability interpretation on the wind farms for further improvement. Here for this study we go for use Taguchi method of optimization to get an optimized output for our work.  This project is useful for the Wind Energy Industries for the sustainable development of wind energy in India.
