To reduce the blades asymmetric loads of large wind turbines operated in the above-rated wind speed region, this work proposes a model predictive individual pitch controller with the linear interpolation model. Results show a significant reduction of 1P (once-per-revolution), 2P, 4P blade asymmetric loads within the limits of pitch rate. The proposed model of wind turbine can describe the characteristic...
For doubly-fed induction generator (DFIG)-based wind power systems, when crowbar-less control methods are used for low voltage ride through (LVRT), the LVRT capabilities are different depending on the specific method. However, because of the limited voltage output of rotor side converter (RSC), there is a limit for crowbar-less control methods. In order to analyze the limit under asymmetrical voltage...
