Mechanical design

The power transmission includes the low-speed shaft, the main support for this shaft, the gearbox and the coupling. Its aim is to transmit the mechanical power to the electric generator in the right conditions to generate electricity. The main shaft is supported on a double row of roller bearings at the front and it is connected to the gearbox by compression ring. 

The coupling between the gearbox and the generator is elastic, enabling it to absorb any misalignments arising during any operating situation.

Diseño eléctrico

The generator is fitted with a dual stator winding enabling the selection of which one of the two is connected to the grid depending on the wind speed, thus optimizing power transformation output and aerodynamic characteristics while reducing the noise level at low wind speeds.

Sistema de Orientación

The wind turbine is fitted with an active yaw system that turns the nacelle so that the rotor remains facing the prevailing wind. The control is informed whether the nacelle is facing the prevailing wind or not through wind sensors located on the outside of the nacelle (redundant for safety reasons).

Brake

Primary aerodynamic brake for air brake feathering.  The mechanical brake is mounted on the high-speed shaft of the gearbox. It consists of a disk on which a fail-safe hydraulic calliper operates.

Torre y Góndola

The wind turbine nacelle protects all of its components from the weather and insulates acoustically the outside from the noise emitted by the machinery. The nacelle frame unit is mounted on the top of the tower. Tower is manufactured in three trunk conical steel sections secured together by flanges, this raises the rotor a height of 55 m.
