Wind energy is the one of the most abundantly available forms of renewable energy, and has emerged as a viable alternative to conventional non-renewable energy sources. The wind electrical generation system is the most competitive of all the environmentally clean and safe renewable energy sources. Electricity derived from wind power provides an alternative to conventional generation that could be used to achieve substantial reductions in fossil fuel use and industrial effluents like carbon dioxide. Current utilization of renewable energy systems in the form of wind, small hydro and bio-gas has led to the massive use of grid-connected and self-excited induction generators (SEIG). Besides being commonly used as drives in the industry, three-phase induction machines have earned much attention as wind generators because of the qualities such as ruggedness, fault tolerance and constructional simplicity, and constitute the biggest sector in the present wind power industry. This thesis consists of theory and background of self-excited induction generators (SEIGs), their dynamic and mathematical modeling, development of a laboratory experimental set-up, development of a thermal model and computational and experimental results of thermal modeling and aluminum-rotor and copper-rotor SEIGs and comparative analysis between the two kinds of SEIGs.
