摘要： The invention relates to a drive unit for a wind turbine, wherein a rotor of the wind turbine is mounted rotatably to a mainframe. The rotor comprises a hub and at least one rotor blade fastened thereto. The drive unit comprises a gear system for converting the rotational speed of the rotor according to a desired gear ratio. The gear system, a planetary gear system, comprises at least one ring gear, a planet carrier, at least two planet wheels, a sun gear, and an output shaft. The wheels of the gear system are preferably designed as gear wheels. Because the sun gear is connected to an output shaft, the rotational energy can be coupled into a generator. It is the aim of the invention to provide a drive unit of a wind turbine that avoids the disadvantages of the prior art. In particular favorable and simple mounting for a rotor of a wind turbine having a robust and cost-reduced drive unit is to be implemented. The aim is achieved by a drive unit having the characteristics of the main claim. One of the characteristics that the invention comprises is that the drive unit has a substantially horizontal rotor axis for rotatably mounting the rotor. Said rotor axis can be indirectly or directly rigidly connected to the mainframe. In such a way, for the first time the advantage is achieved that the forces and loads of the rotor are directly introduced into the mainframe, and the main power flow does not take place in the surroundings of the gear system and cannot lead to harmful deformations there. In addition, the mounting can be done on a central, journal-like rotor axis using smaller and less expensive bearings.

摘要： The invention relates to a method for stopping the rotor of a wind power plant when the blade angles are in the operating position and the tower is inclined to the direction of the wind. According to the invention, in the method, the blade angles of the blades of the rotor are adjusted from the operating position towards the storm position so that at the first step, the blade angles are turned at the first blade angle speed so that the rotor brakes; at the second step, the blade angle speed is reduced so that while in the operating position, the rotor acts to soften the pendulous motion of the tower against the wind; and at the third step, as the pendulous motion of the tower turns to be parallel to the wind, the blade angle speed is increased to enhance the braking.

摘要： A method in connection with a wind turbine installation for damping tower vibrations, in particular a floating wind turbine installation comprising a floating cell, a tower arranged over the floating cell, a generator mounted on the tower that is rotatable in relation to the wind direction and fitted with a wind turbine, and an anchor line arrangement connected to anchors or foundations on the sea bed. The tower's eigenvibrations, ωeig, are damped by, in addition to control with the controller in the constant power or RPM range of the wind turbine, an increment, &Dgr;&bgr;, being added to the blade angle of the turbine blades on the basis of the tower velocities, &Dgr;Z, so that the eigenvibrations are counteracted. The vibrations in &bgr; that have frequency ωeig can expediently be damped by means of a stabiliser with the transfer function Hstab(s) between the tower velocities, &Dgr;Z, and the blade angle, &Dgr;&bgr;, which is such that the loop transfer function H−&bgr;-&Dgr;Z-dot{jωeig)Hstab(jωeig)=−b, which means that: (I) where “b” is a variable depending on the moment and thrust characteristics of the turbine blades.
