Wind Turbine Test Laboratory (LEA) - Wind Institute

Located in the town of Sangüesa, Navarra, it is comprised of a series of cutting-edge technology wind turbine test infrastructures, of international reference, which include:

Zoom

Blade Plant

To perform tests in agreement with Standard 61400-23 (Test on Characterisation of physical properties, static and fatigue test). It has two test positions for blades of up to 85 m. long.

Powertrain

To perform mechanical durability tests on the powertrain (low speed shaft, multiplier, high speed shaft and generator) of wind turbines of up to 5 MW

Electrical test bench

To perform tests on generators and power electronics equipment.

Nacelle test bench

To perform functional tests on the complete nacelle (electrical tests including performance faced with voltage dips, as well as mechanical and thermal tests), and tooling trials as well as to train personnel in assembly and maintenance.

Aerodynamic tunnel

To characterise the actions of 2D aerodynamic profiles and 3D blade tip aero-acoustics.

Compound material laboratory

To optimise the manufacturing processes of components with compound materials, characterisation of process control variables and characterisation of material physical, chemical and mechanical properties.

Experimental farm

To perform field tests on prototypes and certification. It will have 6 calibrated positions of up to 5 MW each one.

Zoom

Field tests

This group performs Power Curve, Energy Quality, Noise and Mechanical Load tests. These tests are authorised by ENAC (proceedings no. 355 LE/803) and are performed in agreement with the IEC regulation. They also have the MEASNET stamp and recommendations.
