摘要： A system for load control of a wind turbine is disclosed. The wind turbine comprises a nacelle having a main structure, a rotor, which rotor comprises at least two rotor blades, each mounted to a rotor hub via a root end of the rotor blade. The rotor hub is connected with a rotatable main shaft which is supported in a bearing structure which can be of any bearing configuration. The rotatable main shaft is connected with a generator for producing electricity. The system further comprises displacement sensors arranged for detecting a displacement. One or more sensors to detect axial displacement are arranged at the root end of the rotor blade in order to detect changes in the axial distance between the root end of the rotor blade and a reference surface on a reference part being fixed to the main structure. The changes in axial distance indicate unwanted loads on the rotor. The system comprises a control circuit coupled with the one or more sensors to mitigate load causing the axial displacement.

摘要： The invention relates to a wind turbine comprising a plurality of individual yaw bearing units and a method of replacing a pad of such a yaw bearing unit. The yaw bearing unit comprises a calliper structure divided into an upper portion and a lower portion, wherein the lower portion can be dismounted without also dismounting the upper portion. An upper pad is provided between a flange providing support for a nacelle and a mainframe of the nacelle. A radial pad is arranged on a radial surface of the upper portion and contacts a stop element located at either ends of the upper portion. An adjustable lower pad is arranged in a through hole in the lower portion and can be replaced via a lower opening in the lower portion. The radial pad can be replaced in a sideward direction by removing one of the stop elements or replacing it in an axial direction by removing the lower portion.

摘要： The invention relates to a wind turbine comprising a rotor with a hub, a nacelle with a mainframe, and a moment bearing arranged between the hub and mainframe. The moment bearing comprises an inner ring and an outer ring between which at least one row of rotatable bearing elements is arranged. The individual bearing elements are substantially held in place by a cage located between the inner and outer rings. The outer ring further comprises a first and a second shoulder for transferring axial loads in both directions from the bearing elements to the outer ring. The moment bearing further comprises at least a first seal element configured to close off the chamber de- fined by the inner and outer rings, wherein said first seal element contacts a contact surface on the outer ring. This provides an improved heat transfer where most of the generated heat is transferred to the mainframe.

摘要： The present invention relates to a method of correcting rotor imbalance and a wind turbine thereof. The correction method comprises measuring the vibrations within at least one time window and determining an imbalance factor and an imbalance phase. The values of the parameters in the equation for calculating the correction action are then updated based on the imbalance factor and an imbalance phase. A correction angle for each of the wind turbine blades is calculated using these adjusted parameters. The correction angle is used to aerodynamically balance the rotor, and a model may be used to determine the initial values of the parameters. Another imbalance factor and imbalance phase is determined based on another set of measurements. This imbalance factor is then used to calculate a mass moment for correcting the mass imbalance in the wind turbine blades. The weight and location of a balancing mass is finally calculated based on this mass moment and installed in the respective wind turbine blades.
