Voltage control of self excited induction generator: for varying wind speeds in isolated mode

Today the world is looking towards the efficient energy generation from renewable energy sources because of extinction of fossil fuels.Wind energy is a promising source of green energy.But the problem associated with this kind of energy id due to varying wind speeds the out put is also varying so it is not possible to integrate it to grid.Here Induction generators are dominantly used because of their advantages in variable speed torque characteristics.In this book an attempt is made to discuss different types of generators used in wind energy and different topologies for control of voltage and frequency of Self Excited induction generator are discussed and new promising methods are proposed for low cost power generation.
