Made AE-61-1320 KW

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.

Electrical Design

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.

Guidance System

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).

Foundation

The wind turbine foundation ensure its stability for all load case conditions and is designed for a wide variety of sites.

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.

Tower and Nacelle

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.

Control system

The MADE AE61 – 1320 kW wind turbine includes a control system that performs all the necessary tasks enabling the wind turbine to operate in automatic mode. This control system is responsible for adjusting all operating sequences and is capable of detecting any defect during operation, triggering the braking devices and keeping the turbine within the pre-established safety margins. The control system is also responsible for supplying the necessary data to a SCADA in order to remotely assess turbine operating status in real time.
