Comparison of fixed speed and doubly-fed induction wind turbines during power system disturbances
TL;DR: In this paper, a reduced order dynamic machine model is derived suitable for modelling both fixed speed and doubly-fed asynchronous generator wind turbines, and the operation of the models during power system disturbances such as network voltage sags and three-phase faults, as well as the possibility of network voltage instability, are investigated.
Journal ArticleDOI
Aeroelastic instability problems for wind turbines
TL;DR: In this article, the authors deal with the aeroelastic instabilities that have occurred and may still occur for modern commercial wind turbines: stall-induced vibrations for stall-turbines, and classical flutter for pitch-regulated turbines.

TL;DR: In this paper, an extensive literature survey over past 25 years on the different aspects of doubly fed induction generators (DFIGs) is presented, which can be used to evaluate the performance of DIGs.
Journal ArticleDOI
Estimation of effective wind speed
TL;DR: In this article, the rotor speed and aerodynamic torque are estimated by a combined state and input observer, and the measured pitch angle is then used to calculate the effective wind speed by an inversion of a static aerodynamic model.

Feedback–feedforward individual pitch control for wind turbine load reduction
TL;DR: In this article, the problem of wind turbine fatigue load reduction by means of individual pitch control (IPC) is addressed by using a two-degree-of-freedom structure consisting of an optimal multivariable LQG controller and a feedforward disturbance rejection controller based on estimated wind speed signals.
