DYNAMIC CUT-IN WIND SPEED FOR WIND TURBINES

摘要

The present subject matter is directed to a system (30) and method (500) for operating a wind turbine (10). More specifically, the system (30) and method (500) determines a dynamic cut-in wind speed for the wind turbine (10) based on one or more environmental conditions. In one embodiment, the method (500) includes providing (502) a predetermined cut-in wind speed for the wind turbine (10) based on at least one estimated environmental condition for a wind turbine site; determining (504) one or more actual environmental conditions near the wind turbine (10) for a predetermined time period at the wind turbine site; determining (506) a variance between the at least one estimated environmental condition and the one or more actual environmental conditions; calculating (508) a dynamic cut-in wind speed based on the variance; and, operating (510) the wind turbine (10) based on the dynamic cut-in wind speed so as to increase wind turbine operational efficiency.
