Abstract
A method of operating a wind turbine having a bearing assembly, a shaft received therein, and at least one sub-system capable of altering a dynamic state of the wind turbine includes monitoring at least one parameter indicative of a load on the shaft; comparing the at least one parameter to a threshold criteria; and when the at least one parameter meets the threshold criteria, altering the dynamic state of the wind turbine to reduce the load on the shaft; and/or altering the state of the bearing assembly to better accommodate the load on the shaft. A control system for the wind turbine includes a controller operatively coupled to the bearing assembly and the at least one sub-system, and at least one sensor for monitoring at least one parameter indicative of a load on the shaft. The controller signals the sub-system or the bearing assembly when the threshold criteria is met.
