Patent number: 12345235Abstract: A method for reducing gear induced noise from a wind turbine is disclosed. A first vibration map and a second vibration map are generated, specifying, for each of a plurality of operating points of the generator, a virtual phase of vibrations originating from gear tooth meshing of the gearbox, relative to a first and second reference phase, at the respective operating points. An overlap between operating points of the first vibration map and operating points of the second vibration map is identified and virtual phases within the overlap are compared, thus deriving a phase offset between the first vibration map and the second vibration map. The virtual phase of vibrations of each of the operating points of the second vibration map are adjusted according to the phase offset, so as to align the first vibration map and the second vibration map, and the first vibration map and the second vibration map are combined into a resultant vibration map.Type: GrantFiled: September 13, 2024Date of Patent: July 1, 2025Assignee: VESTAS WIND SYSTEMS A/SInventors: Peter Mongeau, Kent Tange, Andreas Langbak, Tobias Philipp Roman Duda

Publication number: 20250154931Abstract: A method for controlling operation of a generator for a wind turbine is disclosed. At least one amplitude of a harmonic in the gearbox vibrations is determined. A torque modulating signal for the generator is generated. A phase angle and the amplitude are adjusted during operation of the generator, until a minimum in amplitude of a resultant vibration is reached, thereby obtaining an adjusted torque modulating signal. The adjusted torque modulating signal is injected into the generator, resulting in the resultant vibration of vibrations of the gearbox and vibrations of the generator, corresponding to the harmonic in the gearbox vibrations, being reduced.Type: ApplicationFiled: December 21, 2022Publication date: May 15, 2025Inventors: Peter MONGEAU, Kent TANGE, Nalliboyana DHARMARAJU

Patent number: 12264647Abstract: A method for tracking a gear tooth meshing angle of a gearbox of a wind turbine is disclosed. An initial reference virtual gear tooth meshing angle of the gearbox is selected, and an angular position of a high speed shaft and/or a low speed shaft of the gearbox is monitored. A virtual gear tooth meshing angle relative to the reference virtual gear tooth meshing angle is estimated, based on the monitored angular position of the high speed shaft and/or the low speed shaft and on information regarding topology of the gearbox. A number of full rotations of the high speed shaft and/or the low speed shaft which corresponds to an integer number of full periods of gear meshing of the gearbox is calculated, and the reference virtual gear tooth meshing angle is reset each time the high speed shaft and/or the low speed shaft has performed the calculated number of full rotations. The estimated virtual gear tooth meshing angle is applied to a periodic noise signal of the wind turbine.Type: GrantFiled: September 13, 2024Date of Patent: April 1, 2025Assignee: VESTAS WIND SYSTEMS A/SInventors: Andreas Langbak, Peter Mongeau, Ciprian Biris, Kent Tange
