Chaos Control of Doubly-Fed Induction Generator via Delayed Feedback Control

With the increasing wind power penetration, farms are directly influencing systems, so need to improve quality of system is an open research topic. A Doubly-Fed Induction Generator (DFIG) often used in systems. However, DFIG has a complex structure and works harsh environments, potential faults may occur. Faults can cause fall into chaotic working state, which harmful phenomenon for DFIG, since it makes operating worse, even leading destruction if not fixed on time. This study presents simulations that occurs under specific conditions based Lyapunov’s exponents. The delay feedback controller designed, along with selection appropriate parameters, quickly eliminated, bringing back stable operation.
