Powertrain Test Bench

Designed and constructed to test the powertrain and optionally the electric equipment of wind turbines of up to 8 MW. The powertrain test bench is designed to perform accelerated lifespan tests on mechanical parts. Functional tests can also be performed on these parts:

  • Accelerated lifespan tests on the low speed shaft bearings.
  • Accelerated lifespan tests on gearbox gears and bearings.
  • Functional and load tests on high speed shaft brakes and brake pads.
  • Functional, load and accelerated lifespan tests on the bearings of the generator and on the coupling of the HSS high speed shaft.

Generator Test Bench

Designed and constructed to perform tests on generators and electronic power equipment integrated into wind turbines (6 MW):

  • Functional and accelerated lifespan tests (mechanical/ electrical/thermal) on the generator and power electronics.
  • Electrical transient simulation. Voltage dips.
  • Generator characterisation measurements: Winding resistance, insulation, wave forms, discharge curve, short circuit curve, rotor inertia.
  • Functional tests: No load testing, vibrations, acoustic noise, heating.
  • Overspeed tests and transient surges.

Nacelle Test Bench

Designed and constructed to perform tests on the cooling system, noise measurements and EMC:

  • Functional test on the complete nacelle.
  • Electrical transient simulation. Voltage dips.

Nacelle Installation Bench

Designed and constructed to perform nacelle assembly tests:

  • Field assembly simulation. Possibility of using auxiliary assembly cranes.
  • Simulation of maintenance operations, including major corrections.
  • Training personnel in the assembly and maintenance of wind turbines.
  • Training in evacuation and safety operations in wind turbines.
