Utility
Improved Wind Turbine Safety System
23 Oct 19
The present invention relates to a method, controller, wind turbine and wind farm that advantageously determines an ice throw risk zone (302) for a wind turbine (301), wherein the ice throw risk zone (302) defines an area surrounding the wind turbine (301) within which ice can be thrown from one or more blades of the wind turbine (301); determining whether the determined ice throw risk zone (302) impinges one or more exclusion zones; and if the determined ice throw risk zone (302) impinges one or more exclusion zones, determining an alteration to one or more operating parameters of the wind turbine (301) in order to alter the ice throw risk zone (302) such that the determined ice throw risk zone (302) does not impinge the one or more exclusion zones.

Utility
Increasing active power from a wind turbine
21 Oct 19
The present invention relates to a method for controlling a wind turbine, the wind turbine comprises a rotor connected to a generator, and a rotational speed controller configured to control a speed of the rotor in response to a generator speed reference, and a power controller to control an electric power production, the method comprises the step for receiving a boost command to request a power boost event, so to increase the electrical power production, and imposing a dead band with a dead zone value limit to the rotational speed controller, and wherein the dead band imposes a zero signal to be send to the rotational speed controller, when a speed error is within the dead zone value limit and wherein the dead band imposes an error signal to be send to the rotational speed controller, when a speed error is greater than the dead zone value limit, the error signal being a function of the speed error and the dead zone value limit.
