Wind energy: nacelles on the test bench

04.02.2015

In spring 2015, Germany’s first nacelle test rig is opening

The journey taken by wind turbines from their preliminary design to their market launch is long. Particularly in the final phase, prototypes have to undergo arduous and intensive practical testing. To shorten this period, in spring 2015 a test rig for nacelles will commence operation in Bremerhaven, Germany.


A nacelle is driven on a heavy load transporter into the 30-metre high testing hall. The yellow gantry crane can raise loads of up to 420 tonnes.

Here the mechanical and electrical components can be tested under accelerated conditions. The BINE-Projektinfo brochure “Fast-track testing of nacelles” (15/2014) presents the test rig. It is designed for complete nacelles up to eight megawatts in size. The data obtained here is incorporated in the certification process and makes it possible to fine-tune new wind turbines.

“The tests on the test rig help to increase the reliability of the wind turbines – especially offshore. In addition, the loads acting on the drive train can be reduced by new control strategies,” says Martin Pilas, project manager at the Fraunhofer Institute for Wind Energy and Energy System Technology IWES, in summarising the benefits for manufacturers and wind farm operators.

A load transmission system can simulate all the forces and moments that also act on nacelles in the field. An electricity grid is modelled in what is currently the most powerful grid simulation system in the world. Here, the electrical components of the wind turbines are investigated in regards to grid perturbations, short circuits and emergency stops.

In addition to the nacelle test rig, the Dynamic Nacelle Testing Laboratory (DyNaLab), which is the name of the overall facility in Bremerhaven, is equipped with testing equipment for generators, converters, bearings and main shafts. The project is coordinated by Fraunhofer IWES.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
