Abstract: The present disclosure relates to a control system for a wind turbine comprising more controllers and where at least some of the controllers operate at different sample frequencies. The control system comprises at least two controller units, a first controller (10) for determining an operational value (OV) of a sub-system and a second controller (20) for the sub-system. The second controller operates at a higher sample frequency than the first controller. It is disclosed that a faster reaction to a received demand value (V1), received for controlling the sub-system, can be obtained by setting the operational value (OV) of the sub-system as the sum of an internal operational value (V5) and a difference value (V4).

Abstract: A method and associated control arrangement are disclosed for controlling a de-rated power output of a wind turbine generator, where the wind turbine generator is associated with a predetermined power ramp rate upper limit and operating with a de-rated rotor speed. The method includes ramping the power output from an initial power level to a target power level during a ramping interval. During a first portion of the ramping interval, the power output is ramped at a first power ramp rate less than the power ramp rate upper limit. The method further includes ramping the rotor speed to a predetermined rotor speed value contemporaneously with ramping the power output during the first portion of the ramping interval. The first power ramp rate is determined such that a difference between the power output and the target power level is monotonically decreasing during the entirety of the ramping interval.

Abstract: Embodiments of the invention generally relate to wind turbine generators, and more specifically to improving power production in wind turbine generators. A rotor plane of the wind turbine may be divided into a plurality of sections. A characteristic of wind associated with each section may be determined. An optimal pitch angle may be determined for each section based on the associated wind characteristic. A pitch controller may adjust the pitch angle of a blade to the optimal pitch angle as the blade sweeps through the section.

Abstract: The invention relates to a method for controlling a wind turbine in partial and full load. In order to avoid disadvantages of switching between partial and full load controllers, the wind turbine control system is configured so that both the partial and full load controller provides control action during partial and full load. For that purpose, the partial and full load controllers are configured with variable gains, wherein gain scheduling is performed so that the gain of partial load controller is larger than the gain of the full load controller during partial load and vice verso so that the gain of the full load controller is larger than the gain of the partial load controller during full load.

Abstract: 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. The invention also relates to a wind power plant comprising a power plant controller and at least one wind turbine with a control system according to the above mentioned method.
