Publication number: 20230383730Abstract: A method for detecting a failure condition in one or more components of a wind turbine is provided. The method includes actuating, via a controller, an impact device to generate a vibration having a vibration frequency and a vibration magnitude in the one or more components. The method further includes receiving data indicative of the vibration frequency and the vibration magnitude from a sensor communicatively coupled to the controller. The method further includes determining, via the controller, whether the data indicative of the vibration frequency and/or the vibration magnitude is outside of a predetermined vibration range for the one or more components.Type: ApplicationFiled: May 24, 2022Publication date: November 30, 2023Inventors: Dhanesh Chandrashekar Pathuvoth, Vidyashankar Ramasastry Buravalla

Patent number: 11725698Abstract: The present disclosure is directed to methods for manufacturing a wind turbine slewing ring bearing having an integral stiffener configured to resist deformation of the bearing under a load. More specifically, the present disclosure is directed to methods for manufacturing components of a slewing ring bearing (e.g., an inner, center, and outer race) using near-net-shape (NNS) ring rolling techniques. In particular, the present disclosure is directed to methods for manufacturing slewing ring bearing races, via NNS ring rolling, that are not restricted to conventional (e.g., generally square, rectangular, quadrilateral, trapezoid, quadrilateral) cross-sectional profiles that necessitate attachment of a separate, non-integral stiffener (e.g., a non-integral stiffening plate, stiffening ring, or stiffening assembly).Type: GrantFiled: May 20, 2022Date of Patent: August 15, 2023Assignee: General Electric Renovables Espana, S.L.Inventors: Dhanesh Chandrashekar Pathuvoth, Sujan Kumar Pal

Patent number: 11536247Abstract: A method for reducing extreme loads acting on a component of a wind turbine includes measuring, via one or more sensors, a plurality of operating parameters of the wind turbine. Further, the method includes predicting at least one blade moment of at least one rotor blade of the wind turbine based on the plurality of operating parameters. The method also includes predicting a load and an associated load angle of the at least one rotor blade as a function of the at least one blade moment. Moreover, the method includes predicting a pitch angle of the at least one rotor blade of the wind turbine. In addition, the method includes generating a load envelope for the component that comprises at least one load value for the pitch angle and the load angle. Thus, the method includes implementing a control action when the load is outside of the load envelope.Type: GrantFiled: October 24, 2019Date of Patent: December 27, 2022Assignee: General Electric CompanyInventors: Prashanth Kumar Reddy Vaddi, Dhanesh Chandrashekar Pathuvoth, Venkata Krishna Vadlamudi

Patent number: 10502264Abstract: A bearing assembly for a wind turbine includes a bearing comprising an outer race, an inner race rotatable relative to the outer race, and a plurality of roller elements positioned within at least one raceway defined between the outer and inner races. Further, at least one of the outer race or the inner race defines a radial opening. The bearing assembly also includes at least one ball plug positioned within the radial opening of at least one of the outer race or the inner race. The ball plug(s) is removable such that the plurality of roller elements can be inserted between the outer and inner races. Moreover, at least a portion of the ball plug(s) has a tapered cross-section.Type: GrantFiled: August 22, 2018Date of Patent: December 10, 2019Assignee: General Electric CompanyInventors: Dhanesh Chandrashekar Pathuvoth, Adam Daniel Minadeo, William Max Gobeli

Patent number: 10190571Abstract: The present disclosure is directed to a rotor blade assembly for a wind turbine. The rotor blade assembly includes a rotor blade having a blade root section and a rigid ring insert. The rotor blade has pressure and suction sides extending between leading and trailing edges. The blade root section includes an end face configured to attach the rotor blade assembly to a hub. Further, the blade root section includes a span-wise end portion defined by inner and outer circumferential components separated by a radial gap. The radial gap includes a first laminate material embedded between the inner and outer circumferential components at a first span-wise depth and a second laminate material embedded between the inner and outer circumferential components at a second span-wise depth. Thus, the rigid ring insert is disposed in the radial gap and embedded between the first and second laminate materials.Type: GrantFiled: July 1, 2015Date of Patent: January 29, 2019Assignee: General Electric CompanyInventors: Srikanth Samudrala, Biju Nanukuttan, Dhanesh Chandrashekar Pathuvoth, Willem Jan Bakhuis
