Patent number: 11661919Abstract: A method for controlling a wind turbine connected to an electrical grid includes receiving, via a controller, a state estimate of the wind turbine. The method also includes determining, via the controller, a current condition of the wind turbine using, at least, the state estimate, the current condition defining a set of condition parameters of the wind turbine. Further, the method includes receiving, via the controller, a control function from a supervisory controller, the control function defining a relationship of the set of condition parameters with at least one operational parameter of the wind turbine. Moreover, the method includes dynamically controlling, via the controller, the wind turbine based on the current condition and the control function for multiple dynamic control intervals.Type: GrantFiled: January 20, 2021Date of Patent: May 30, 2023Assignee: General Electric CompanyInventors: Frederick Wilson Wheeler, Dayu Huang, George Theodore Dalakos, Ameet Shridhar Deshpande, Su Liu, Dhiraj Arora, Siyun Wang

Patent number: 11649804Abstract: A system and method are provided for controlling a wind turbine of a wind farm. Accordingly, a controller implements a first model to determine a modeled performance parameter for the first wind turbine. The modeled performance parameter is based, at least in part, on an operation of a designated grouping of wind turbines of the plurality of wind turbines, which is exclusive of the first wind turbine. The controller then determines a performance parameter differential for the first wind turbine at multiple sampling intervals. The performance parameter differential is indicative of a difference between the modeled performance parameter and a monitored performance parameter for the first wind turbine. A second model is implemented to determine a predicted performance parameter of the first wind turbine at each of a plurality of setpoint combinations based, at least in part, on the performance parameter differential the first wind turbine.Type: GrantFiled: June 7, 2021Date of Patent: May 16, 2023Assignee: General Electric Renovables Espana, S.L.Inventors: Samuel Bryan Shartzer, Scott Charles Evans, Arunvenkataraman Subramanian, Dhiraj Arora, Samuel Davoust

Patent number: 11231012Abstract: A system and method are provided for controlling a wind turbine of a wind farm. Accordingly, a controller determines a performance differential for the wind turbine at multiple sampling intervals of a yaw event. The controller determines a trendline for the wind turbine correlating the performance differential to a deviation of a wind direction at each of the multiple sampling intervals from an first yaw angle. A difference between an angle associated with the vertex of the trendline and the first yaw angle are utilized by the controller to determine a yaw angle offset. The yaw angle offset is used to adjust a second yaw angle of the wind turbine.Type: GrantFiled: September 22, 2020Date of Patent: January 25, 2022Assignee: General Electric Renovables Espana, S.L.Inventors: Samuel Bryan Shartzer, Scott Charles Evans, Dhiraj Arora, Bernard P.
