Analysis of horizontal axis wind turbine generators

Abstract

In India wind power has emerged as the leading green energy newlinetechnology with an average growth rate of 30 India is the worlds fifth newlinelargest producer of wind power with a total installed capacity of 14723 MW newlineas of July 2011 Wind power has been concentrated in few regions especially newlinethe southern state of Tamil Nadu which maintains its position as the state newlinewith the largest wind power installation with 6160 MW till July 2011 newlineAlmost all the Wind Turbine Generators WTG has the axis of rotation in newlinehorizontal direction and hence they are termed as horizontal axis WTG newlineGenerally the Indian power systems are not sufficient to cater to the needs of newlineincrease in wind farms in a few rural areas where the existing transmission newlineand distribution grids are very weak The power quality of the grid influences newlinethe performance and safety of the WTG and the life time of mechanical and newlineelectrical components Hence rather than the technical advancements of newlineWTG the power quality issues are also to be studied newline newline
