Estimating the term…
A wind turbine including yaw control comprising a controller receiving an input signal, and providing an output control signal to a yaw actuator. The input signal to the controller is based on: a first feedback signal that is indicative of the relative wind direction determined with respect to the wind turbine, wherein the first feedback signal is filtered with a first low pass filter; and a second feedback signal that is indicative of the activity of the yaw actuator. The control technique of the invention significantly improves the ability of a yaw system to maintain a zero degree yaw error during steady state wind conditions, or in other words to maintain an accurate heading of the nacelle pointing into the wind, as well as reducing the maximum yaw error experienced during yaw system activation.
A wind turbine including a nacelle mounted on a tower, and a yaw control system that is operable to yaw the nacelle with respect to the tower, the yaw control system comprising:
A control method for a wind turbine including a nacelle mounted on a tower, and a yaw system including a yaw actuator that is operable to yaw the nacelle with respect to the tower, the method comprising:
A controller for a wind turbine system including a nacelle mounted on a tower, a yaw system including a yaw actuator that is operable to yaw the nacelle with respect to the tower, a rotor having a plurality of blades, wherein the controller includes a processor, a memory module, and an input/output system, and wherein the memory module includes a set of program code instructions which when executed by the processor, implements an operation, comprising:
