Abstract: The present subject matter is directed to a system and method for sequencing Light Detecting and Ranging (LIDAR) sensor beam signals from a LIDAR sensor mounted on a nacelle of a wind turbine with the rotor position of the wind turbine so as to improve signal availability. More specifically, the method includes generating, via the LIDAR sensor, one or more laser signals towards the rotor of the wind turbine, the rotor having one or more rotor blades. The method also includes receiving, via a controller, a rotor position of the rotor of the wind turbine. Thus, the method further includes coordinating, via a control algorithm programmed within the controller, the rotor position with the one or more laser signals of the laser sensor so as to minimize interference between the laser signal(s) and the rotor blades during rotation of the rotor.

Abstract: The present disclosure is directed to systems and methods for de-icing a rotor blade of a wind turbine. The wind turbine has a nacelle mounted atop a tower. The nacelle has a rotor with a rotatable hub having rotor blade mounted thereto. The method includes shutting down the wind turbine in response to detecting ice on the rotor blade. The method also includes positioning the wind turbine in a de-icing position, the de-icing position including at least one of yawing the nacelle of the wind turbine such that the rotor is in a down-wind location of the tower or pitching the rotor blade such that a leading edge of the rotor blade is facing the tower. Another step includes de-icing the rotor blade while the rotor is in the de-icing position.

Abstract: A method for controlling a wind turbine may generally include operating the wind turbine at an initial power output that is greater than a rated power output associated with the wind turbine. The wind turbine may have an anticipated operational life at the rated power output. In addition, the method may include decreasing a power output of the wind turbine over time in order to maintain an actual operating life of the wind turbine substantially equal to or greater than the anticipated operational life. A final power output of the wind turbine at an end of the anticipated operating life may be less than the rated power output.
