摘要： A method of operating a wind turbine having a bearing assembly, a shaft received therein, and at least one sub-system capable of altering a dynamic state of the wind turbine includes monitoring at least one parameter indicative of a load on the shaft; comparing the at least one parameter to a threshold criteria; and when the at least one parameter meets the threshold criteria, altering the dynamic state of the wind turbine to reduce the load on the shaft; and/or altering the state of the bearing assembly to better accommodate the load on the shaft. A control system for the wind turbine includes a controller operatively coupled to the bearing assembly and the at least one sub-system, and at least one sensor for monitoring at least one parameter indicative of a load on the shaft. The controller signals the sub-system or the bearing assembly when the threshold criteria is met.

摘要： A generator for a wind turbine is disclosed. The generator comprises a rotor configured to rotate about a rotational axis, and at least one stator arranged next to the rotor. Each stator comprises at least one flux-generating module facing the rotor but spaced therefrom, thereby forming an air gap between the rotor and each flux-generating module. Each stator also comprises at least one bearing unit, each bearing unit comprising a body defining a cavity with an open end facing the rotor. The generator further comprises a source of pressurized fluid communicating with each bearing unit, and the body of each bearing unit directs the fluid towards the rotor to help maintain the air gap between the rotor and each flux-generating module. Thereby the air gap between the rotor and the flux-generating modules is controlled by means of the fluid bearing units. The invention further provides a wind turbine comprising such a generator.

摘要： A bearing assembly for a wind turbine includes a bearing housing and a bearing surface defining a passageway configured to receive a shaft. The bearing surface includes a stationary portion and a movable portion, the movable portion being defined by a movable member coupled to the bearing housing. The movable member is movable between a first position, wherein the movable portion is flush with the stationary portion such that the bearing surface is smooth, and a second position wherein the movable portion is spaced from the stationary portion to define a fluid cavity in the bearing surface. A method of operating a plain bearing assembly includes operating the plain bearing assembly as a hydrostatic plain bearing during low dynamic conditions and operating the plain bearing assembly as a hydrodynamic plain bearing during high dynamic conditions.
