20110001319 | DIAGNOSIS OF PITCH AND LOAD DEFECTS - The invention relates to a method, system and computer readable code for diagnosis of pitch and/or load defects of e.g. wind turbines as well as wind turbines using said diagnosis method and/or comprising said diagnosis system. | 01-06-2011 |
20110305568 | PITCH CONTROL OF A WIND TURBINE - A wind turbine control system suitable for minimising actuation of pitch actuators is disclosed. The control system uses an error gain schedule in full load control for reducing pitch actuation when the difference between the rotor speed and the reference rotor speed is not critical for the load of wind turbine components. The error gain schedule may be a nonlinear function which reduces the gain for low rotor speed errors. The use of the error gain schedule may reduce wear of the pitch actuators and may improve reduction of structural oscillations since focus removed from tracking the rotor speed reference when the speed error is low. | 12-15-2011 |

20130144449 | WARNING A WIND TURBINE GENERATOR IN A WIND PARK OF AN EXTREME WIND EVENT - The disclosure is provides for warning a wind turbine generator (WTG) in a wind park of an extreme wind event. According to one embodiment, one or more front line WTGs of the wind park that detect extreme wind events and provide the warning are adaptively selected based on a measured wind direction. Thus, the selection of front line WTGs is adaptive to changing wind conditions. In another embodiment, a wind park includes a group of one or more WTGs of a first type located in an inner region of the wind park and a plurality of WTGs of a second type located in an outer region of the wind park that at least partially surrounds the inner region. The first type of WTG is structurally weaker and/or rated for higher performance than the second type of WTG. | 06-06-2013 |

20140207296 | DISABLEMENT OF WIND TURBINES IN A WIND PARK - Embodiments of the invention generally relate to wind turbine generators, and more specifically to the deactivation of wind turbines in a wind turbine park. A wind park controller may be configured to retrieve data indicating fatigue experienced by each wind turbine of the wind turbine park, and deactivate those turbines determined to be the most fatigued, thereby increasing the lifetime of turbines in the wind turbine park. | 07-24-2014 |
