Abstract: A method 400 of predicting tonal noise produced by a wind turbine is disclosed. The method comprises acquiring 410 a first set of vibration data, the first set of vibration data being from a plurality of vibration sensors positioned at different locations about a wind turbine drivetrain when the wind turbine drivetrain is undergoing testing in a test rig; acquiring 420 a second set of vibration data, the second set of vibration data being from a plurality of vibration sensors positioned at different locations about the same or a similar wind turbine drivetrain when located in a wind turbine; acquiring 430 noise data including tonal noise produced by the wind turbine; identifying 440 a vibration sensor of interest using vibration data of the second set of vibration data and the noise data; determining 450, for the identified sensor, a first relationship between vibration data of the first set of vibration data and the second set of vibration data; and determining 460, for the identified vibration sensors, a second relationship between the first set of vibration data and tonal noise produced by a wind turbine based on the first relationship.

Abstract: A wind turbine generator includes a gearbox, wherein the gearbox includes a planetary gear system, wherein the planetary gear system includes a carrier assembly, wherein the carrier assembly includes a carrier supporting at least one planetary gear that is rotatably mounted through a bearing on a shaft, wherein the shaft is fixed in a bore defined by the carrier. The carrier assembly includes interlocking means to prevent angular movement of the shaft relative to the bore. This improves the robustness of the coupling between the shaft and the bore of the carrier.

Abstract: A method of starting a wind turbine in a cold climate environment includes providing a wind turbine in the cold climate environment in a stand-still or near stand-still condition; allowing the rotation speed of the rotor to increase during start up of the wind turbine; optimizing heat generation within the gear box; and generating power using the wind turbine, wherein heat generation within the gear box is optimized prior to providing the generated electrical power to an electrical grid. Optimizing heat generation within the gear box may include maximizing internal power losses in the gear box during start up. This may allow the start up to be achieved without using external heaters. Aspects of this method may be used during periods of low wind conditions in cold climate environments so that once sufficient wind conditions are reestablished, the wind turbine is ready for immediate power production.
