Abstract :
This paper is concerned with the harmonic behavior of variable-speed wind turbines during a control fault. Different topologies for the power-electronic converters are considered, namely two-level and multilevel converters. A three-mass drive train model is considered, and a fractional-order control strategy is proposed for the wind turbines. The performance of disturbance attenuation and system robustness is ascertained. Finally, conclusions are duly drawn.
