ABSTRACT
The use of Cage induction machines in wind generation is widely accepted as a generator of choice. During self-excitation the variation in the value of magnetizing inductance, due to saturation, is the main factor that stabilizes the growing transient of generated voltage and then to continue to oscillate at a particular frequency and voltage in the steady state. The experimental results are proven that the controlled shunt capacitor SEIG maintains a constant terminal voltage over wide variety of loads and changes in speed, and hence is a reliable and cost effective electric generator controlled system. In this paper an attempt has been made to improve the voltage profile of a self-excited induction generator. And, a new methodology based upon GENETIC ALGORITHM (GA) is proposed to compute the design of the wind plant as a efficient one. Further efforts are made to control the terminal voltage under loaded conditions. The inverter will control the exciting current appropriately according to the variation of the wind velocity, and control the output power of induction generator.
