GE's Power Conversion business (NYSE: GE) has signed a turnkey contract with the Lindoe Offshore Renewables Center (LORC), a Danish center for test of renewable energy technology, for the construction, commissioning and handover of one of the world's most advanced facilities to test wind turbine nacelles with an output power of up to 10 Megawatts (MW). The Lindoe Nacelle Testing project (LNT) will be located in the Lindø Industrial Park on Funen, Denmark's fourth-largest island. It will be ready for first tests in 2014.

The function tester will incorporate GE’s drivetrain, grid simulation, control systems and foundation work. It is comprised of: medium voltage switch gear, transformers, inverter system DDPM (direct drive permanent magnet) motor, HMI (human-machine interface) and foundation. GE will carry out the installation, commissioning, and remote service for the project. The medium voltage inverter system is a further development of GE’s existing MV7000 series, and is one of the most compact medium voltage inverters on the market. The MV7000 is based on tried-and-tested GE technology using dynamic control properties and low grid interference.
“GE is extremely pleased and proud to be a partner for LORC in building an outstanding test bench that will lead the wind industry into the future of a safer supply of renewable power”, says Franz Hubl, Global Business Leader - Test Systems, at GE Power Conversion. “As a world leader in this field, we have significant experience to contribute.”
The new nacelle tester will enable LORC to test the functionality and performance of wind turbine nacelles by using a specially designed adapter that enables the turbine hub and all field operational software and hardware—including pitch control—to be included in the test. It will open up a wide range of opportunities to test wind turbine controllers inside the nacelle, using highly realistic test conditions at 33kV level, which is unique in the test system business.
“We choose to work with GE because of their extensive knowledge in the wind power industry and their worldwide references for test systems,” says Ove Poulsen, Chief Executive Officer at LORC. “GE also provided us with a technical solution that best fits the requirements for this project. Users will be able to carry out a full range of tests on their equipment without having to adapt their turbine software or hardware. Because the test bench can be connected to a “virtual” wind farm (created by separate system), it will be able to operate as HIL – Hardware in the Loop.”
The test bench has a modular design that will enable it to be adapted to future needs. For example, its grid simulator power can be increased at a later date and thereby increase its functionality to carry out extended FRT (Fault Ride Through) tests - simulations of wind turbine systems to remain connected to the supply during grid malfunctions and to help stabilize it.
LNT will be able to meet the demands for testing of tomorrow’s offshore wind turbines in a facility where national grid codes can be tested in combination with loads caused by rapidly changing wind speed conditions. Electrical malfunctions and turbine protection systems have historically led to unforeseen excessive loadings of mechanical components and thereby reduced expected life-time. At LNT it will be possible to verify the stress levels under numerous different load cases, thereby helping to improve long term reliability.
GE was helped in winning the contract by the fact that it already has worldwide references in test systems for the wind power industry, and that it was able to offer LORC a technical solution that best fits its requirement. It is alone in producing direct drive permanent magnet motors in the double-digit megawatt range suitable for wind turbines, it offers a flexible automation and visualization system, and it owns important intellectual property rights on grid simulation.Paul Floren

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
