Abstract: A system for repairing dents in a wind turbine tower section may generally include a dent repair tool having a tool hub and a plurality of arms configured to extend radially outwardly from the tool hub towards an inner surface of the tower section. The tool may also include a linear actuator configured to linearly actuate a plunger of the actuator arm relative to the tool hub such that the plunger applies a radially outward force against the inner surface of the tower section at or adjacent to a location of a dent formed in the tower section. In addition, the system may include a load sensor configured to provide an indication of a load associated with the radially outward force applied against the inner surface of the tower section by the plunger and a controller configured to monitor the load based on signals received from the load sensor.

Abstract: The present disclosure is directed to a method for minimizing energy loss caused by yaw untwist of a nacelle of a wind turbine. The method includes monitoring, via at least on sensor, one or more wind conditions near the wind turbine. The method also includes processing, via a controller, the one or more wind conditions for a given time interval. Further, the method includes monitoring, via the controller, a position of the nacelle. The method also includes triggering, via the controller, a yaw untwist operation when the position of the nacelle has rotated from an original position above a predetermined yaw threshold and the processed wind conditions are below a predetermined wind condition threshold.

Abstract: The present subject matter is directed to a system and method for operating a wind turbine. More specifically, the system and method determines a dynamic cut-in wind speed for the wind turbine based on one or more environmental conditions. In one embodiment, the method includes providing a predetermined cut-in wind speed for the wind turbine based on at least one estimated environmental condition for a wind turbine site; determining one or more actual environmental conditions near the wind turbine for a predetermined time period at the wind turbine site; determining a variance between the at least one estimated environmental condition and the one or more actual environmental conditions; calculating a dynamic cut-in wind speed based on the variance; and, operating the wind turbine based on the dynamic cut-in wind speed so as to increase wind turbine operational efficiency.
