Analysis and Control of Wind Driven Self-Excited Induction Generator for Isolated Applications

For isolated applications, the 3self-excited induction generator driven by wind energy source is more suitable, where the minimum excitation capacitance required for self-excitation of 3induction generator is taken up in this work and the detailed analysis is carried out to determine the range of wind speed variation and consumer demand for the designed capacitance value. An electronic load controller is designed to maintain the load voltage constant for these variations. The excess power resulting as a consequence of rise in load voltage due to variation in load is pumped to dump load along with battery storage. Simulation for battery feeding the consumer load in the absence of wind power has been undergone. Exhaustive simulations have been carried out for such a scheme and the results have been presented in this paper.
