Vineet Kumar Tiwari, Satyam Prakash, Abdul Zeeshan

This paper proposes a design of a speed control of three phase induction motor fed from wind turbine using genetic algorithm. The wind turbine acts as a prime-mover for doubly fed induction generator. To make the system stable, proper monitoring is required or sometimes an auxiliary system can also be a good option, which can support the primary system during undesirable conditions. The three phase induction motor has wide applications in industries due to its rugged construction, efficiency and low cost. Genetic algorithm is used for estimation of feedback controller parameters for three phase induction motor fed from wind turbine .Genetic algorithm offers certain advantages such as simple computational steps, derivative free optimization, reduced no. of iteration and assured near global optima. The simulation results show a significant enhancement in shortening development time and improving dynamic performance of the induction machine compared to the conventional speed control of induction motor drive.
