The present invention provides a bearing housing () for accommodating a rotor shaft () of a wind turbine. The bearing housing includes a flange () for connecting the bearing housing to a main frame () of the wind turbine. The flange having a connecting surface () to be attached to the main frame. Thereby, at least parts of the connecting surface, when seen from the top of the bearing housing, would be located below the rotor shaft.

Bearing housing

A damper system for damping vibrations of a wind turbine having a tower, a nacelle, and at least one rotor blade is provided. The damper system includes a mass for damping vibrations of a wind turbine and at least one actuator adapted for actively controlling the mass, wherein the at least one actuator is connected to a portion of the wind turbine and to the mass.

Active tower damper

The hub for the rotor () of a wind energy turbine () comprises a hollow body () rotatable around a rotation axis and provided with at least one flange () for mounting to the hollow body () a bearing for a rotor blade () and at least two stiffening webs () integrally formed with the hollow body () and radially extending within a flange area () of the hollow body () surrounded by the flange () to the center () of the flange area (), wherein at least two openings are provided within the flange area () of the hollow body ().

Reinforced hub for the rotor of a wind energy turbine

A method for operating a wind energy system is provided comprising the steps of setting the value of an operational parameter of the wind energy system, measuring a yield parameter of the wind energy system and measuring a condition parameter. Further, the method comprises the step of calculating an optimized value of the operational parameter based on historical data and the outcome of the measurements. The method further comprises the step of resetting the operational parameter to the optimized value of the operational parameter wherein the resetting is such that the yield parameter is optimized. Further, a wind energy system is provided having a sensor unit for measuring a yield parameter of the wind energy system, a sensor for measuring a condition parameter, an actuator for adjustment of at least one adjustable part of the wind energy system, and a self-learning controller. The self-learning controller is connected to the sensor unit and the actuator and receives measurement data from the sensor unit. The self-learning controller performs optimization calculations based on the measurement data and sends instruction signals to the actuator based on the outcome of the optimization calculations for the adjustment of the adjustable part of the wind energy system. The instruction signals are such that the yield parameter is optimized.

Wind energy system and method of operation thereof

To facilitate transport and assembly during the erecting of wind power plants, a two-part base frame is proposed for the azimuthal adjustment of the gondola on the tower of the wind power plant, the lower part of whichhas the azimuthal drive deviceand the upper partof which has the drive train. Both parts are pre-assembled at the factory, set onto the tower, and screwed tight onto each other at their connection point

Base frame for mounting the shaft of the rotor of a wind power plant onto the plant tower

The invention involves a coupling device for a wind power plant with a rotor shaft that carries at least one rotor blade of the wind power plant, a gear shaft running coaxially to the rotor shaft, and a coupling device coupling the rotor shaft to the gear shaft, whereby the coupling device has at least one connection element that can be detachably affixed on the rotor shaft to an attachment element designed to create a positive locking connection, and one coupling element designed to create a friction-fit connection between the connection element, on the one hand, and an additional connection element and/or the gear shaft, on the other hand.
