SYSTEM AND METHOD FOR VARIABLE TIP-SPEED-RATIO CONTROL OF A WIND TURBINE

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 309 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 10 along a torque constraint boundary 312 of the first and second operating regions. 本主题针对种用于操作风轮机以便通过使用可变末梢速度比控制增加功率产生的系统及方法。在个实施例中，该方法包括限定与非饱和转矩范围相关联的第操作区域，以及与饱和转矩范围相关联的第二操作区域。此外，该方法包括监测风轮机的转矩输出。该方法还包括连续地调整风轮机的末梢速度比设置点，以便沿第操作区域和第二操作区域的转矩约束边界操作风轮机。
