System and method for variable tip-speed-ratio control of a wind turbine

Abstract:

The present subject matter is directed to a system and method for operating a wind turbine so as to increase power production by utilizing variable tip-speed-ratio control. In one embodiment, the method includes defining a first operating region associated with an unsaturated torque range and a second operating region associated with a saturated torque range. Further, the method includes monitoring a torque output of the wind turbine. The method also includes continuously adjusting a tip-speed-ratio set point of the wind turbine so as to operate the wind turbine along a torque constraint boundary of the first and second operating regions.
