    Abstract: Embodiments herein describe a wind turbine controller that includes a thrust limiter for controlling the thrust of the blades of wind turbine using an estimate of the air density at the wind turbine. In one embodiment, the controller receives the blade flap load indicating the current load on one of the blades which varies linearly to the air density experienced by the wind turbine. In one embodiment, the controller determines the mean of a plurality of the blade flap load values measured during a predefined time period. Using a transfer function, the controller converts the mean of the blade flap loads to an estimate of the air density at the turbine. Generally, higher air density results in greater loads on the blades while lower air density results in lower loads on the blades.

    Abstract: A method of controlling a wind turbine. The wind turbine is controlled during a variable speed period in accordance with a variable speed region of a partial load speed curve so that a power of the wind turbine is below a rated power and a generator speed of the wind turbine is below a rated generator speed. During a boost period the wind turbine is controlled in accordance with a boost region of the partial load speed curve so that the power is below the rated power and the generator speed is above the rated speed. During a full load period the power is at the rated power and the generator speed is at the rated speed.

    Abstract: Aspects of the present invention relate to a method (100) for controlling one or more wind turbine generators (14). The method (100) comprises: receiving (102) a trigger signal, and implementing (104) an active power boost mode during a predetermined time period in response to receiving the trigger signal. The active power boost mode comprises: disregarding (106) further trigger signals; and generating (108) one or more upper active power limits for each of the one or more wind turbine generators (14), wherein, during at least a first portion of the predetermined time period, the one or more upper active power limits are fixed (110) at an active power boost level that is greater than a nominal active power level of the one or more wind turbine generators (14).
