    Germany’s largest nacelle test rig inaugurated

    Germany’s largest test rig for wind turbine nacelles is now in Bremerhaven. Here, drive trains with up to eight megawatts can be tested. A load transmission system mechanically simulates the wind loads occurring in the field. The Fraunhofer Institute for Wind Energy and Energy System Technology IWES recently commissioned the nacelle test rig.  more...

    Rotor blade, nacelle and foundation put to the test

    Whether on land or in the sea, wind turbines are getting bigger and the towers higher. All components undergo various preliminary tests, in order to ensure that they can withstand the strains that wind and weather place on them. In recent years, large test facilities have become available in Germany, in which complete rotor blades, nacelles, and foundations are tested. On 21 October 2015, centres will present their supply ranges at a workshop for experts.  more...

    Safely navigating jets close to wind farms

    Until now, it has been difficult or even impossible to construct wind turbines near radio range beacons or radar systems used for navigating air traffic. These systems block what would otherwise be suitable locations. The extent to which rotors deflect or change signals has, however, not yet been studied in any scientific detail. Two research teams in Braunschweig are therefore working in separate projects on these basic data.  more...

    Stable grid with 100 per cent green electricity

    In a power grid, the energy provided must always be equal to the power demanded. Only then can frequency and voltage remain stable. Ensuring this is the task of grid operators. But when volatile — meaning not arbitrarily adjustable — energy sources are the main sources of electrical energy, grid operators face a challenge.  more...

    Testing towers and foundations

    Manufacturers are offering ever larger and more powerful wind turbines for utilising wind power. As the wind turbine sizes increase, the wind and weather take an increasing toil on the structures and turbine components. Hanover University’s Test Center Support Structures opened in 2014 to enable the components used for the tower and foundations to be tested and optimised in advance.  more...

    Energy research on course to delivering the energy transition

    The German federal government recently published the National Action Plan on Energy Efficiency. The concept is specifically aimed at winning over all actors in society in achieving greater energy efficiency. A few days later, the German Federal Ministry for Economic Affairs and Energy announced its research funding for the German federal government’s 6th Energy Research Programme. In the BINE interview, Dr Rodoula Tryfonidou from the responsible department in the German Federal Ministry for Economic Affairs and Energy talks about the contribution made by energy research in bringing about the Energiewende – Germany’s energy transition.  more...

    Heating system keeps rotor blades ice-free

    In cold climate zones, the wind is particularly strong meaning best conditions for a wind turbine. However, in the cold temperatures there is the danger of ice that can freeze onto rotor blades. This can lead to imbalances, impairment of the rotor blade’s aerodynamics and a drop in the efficiency of the turbine. The so-called carbon-nanotube coating offers a solution.  more...

    Fast-track testing of nacelles

    In Bremerhaven, a test rig is being developed that can test complete wind turbine nacelles in the multi-megawatt class. Unprecedented: a load transmission system mechanically simulates the wind loads occurring in the field. The researchers are investigating the electrical components using a simulated electricity grid. Laboratory tests are also providing information on how wind turbine concepts can be improved. With these properties, the test rig has the world’s most powerful grid simulation system.  more...

    New coating protects masts from corrosion

    Submerged sections of offshore plants provide the ideal habitat for colonisation by mussels and microorganisms. This can lead to biologically-induced corrosion and premature wear. To inhibit this, new coatings and surface structures are being developed by 14 partners from science and industry in the Foulprotect project. These are intended to protect plant foundations against "biofouling".  more...

    Producing rotor blades more quickly

    Scientists at the University of Bremen have developed a new automated process for the production of rotor blades together with partners from industry. A textile product is first cut to size mechanically, stacked, shaped in accordance with the subsequent blade design and then placed in the negative mould. This is followed by the injection of the resin. The process is intended to shorten production time and improve quality.  more...
