The invention relates to a wind turbine comprising a rotor shaft (), a multiplier () with at least one planetary-type stage and a generator inside a frame (). The inventive turbine also comprises a first tubular casing () which is solidly connected to the frame () and which houses the rotor shaft (). According to the invention, one end of the rotor shaft is solidly connected to the hub of the rotor, while the other end thereof is solidly connected to the planet carrier () of the multiplier unit. The aforementioned first casing includes a bearing () for supporting the rotor shaft (). The invention also comprises a second casing () which is equipped with a bearing () for supporting the planet holder (), one end of said second casing being solidly connected to the crown gear of the first planetary stage of the multiplier unit () and the other end thereof being solidly connected to the first casing () and to the structure of the frame ().

Wind turbine

The invention relates to a method of producing large parts based on composite materials, such as the roots of blades for wind generators. The inventive method comprises the following steps consisting in: helically winding a band of fibre- and resin-based composite material around a mould; applying a removable protective sheet to the surface of the body; applying a heat-shrinkable strip to the sheet; compacting the laminate thus formed under a vacuum; curing the resin; aligning the cured body, machining the transverse surface to be applied to the blade and forming axial housings in said surface; and positioning and affixing inserts in the axial housings in order to secure the blade.

Method of producing large hollow parts based on composite materials

Structural beam of a wind turbine blade comprising a body-root and a body-trunk in the form of a box with a section decreasing towards the blade tip, comprising various piles each formed by various layers of carbon fiber impregnated with a synthetic resin, located on the upper and lower areas, intercalated between various layers of fiber glass impregnated with synthetic resin arranged along its perimeter, including between two piles, at least one layer of reinforcing material on each of the side areas enveloped by an adhesive resin film. The invention also comprises a procedure for the manufacture of the structural beam which, amongst other stages, includes the application of the layers mentioned onto a mold and the beam curing process.

Structural beam for a wind generator blade production method thereof

The invention relates to a wind turbine () which is connected to an electrical power grid () and which uses a magnet generator () as the only electrical power generator element both in the normal operation thereof and during periods in which the turbine is disconnected from the electrical power grid. The aforementioned wind turbine can perform operations in order to maintain the wind turbine systems operational, with the continued generation of electrical power, and to adjust the quantity of electrical power produced for power consumption during the periods in which the turbine is disconnected from the electrical power grid.

Method of maintaining wind turbine components operational and a turbine comprising components suitable for operational maintenace

The present invention relates to a method for operating a converter system of a wind turbine, wherein the converter system includes converter modules capable of converting electric power produced by a generator to electric power applicable to a utility grid. The converter modules include generator inverters and grid inverters. The method determines the enabling/disabling of the converter modules in response to a parameter related to the variable amount of electric power being produced by the generator. Advantages of the present invention are optimisation of power efficiency of the converter modules and improved reliability of the converter modules. Another advantage is the capability of fast enabling and disabling of the converter modules.
