Hamburg, Germany [RenewableEnergyWorld.com] REpower Systems AG has received the first unit certificate from Germanischer Lloyd (GL) for new turbines in its turbine portfolio. The certificate is the first ever that has been issued for a wind turbine (generation unit) with a double-fed generator system. It confirms that the technical system implemented by the company meets the high requirements of the grid system in Germany.
The measurements required for the certification were conducted on a REpower MM82 with a rated power of 2.05 megawatts, located at the Dollerup wind farm near Flensburg. Dr. Uwe Jönck from GL’s Department of Engineering and Safety Technology, handed over the certificate yesterday to the head of Development at REpower, Peter Quell.
“The unit certification for the wind turbine REpower MM82 is one of the first which has been issued by us under the new ordinance SDLWindV,” Dr. Jönck said.
In order to obtain the certification, simulation models for the characteristics of the wind turbine on the grid needed to be further developed and then validated by comprehensive tests in real operation.
REpower said that it is important to have a good working relationship with the operators, in order to maintain test locations in Schleswig-Holstein in the future. The operators of the Dollerup wind farm, which consists of two REpower MM82 wind turbines are Dolleruper Burgerwindpark GmbH & Co. KG and Jensen & Falke, Windpark Dollerup GmbH & Co.KG.
The unit certificate is required for new generator systems in conformance with the Renewable Energy Sources Act (EEG) and the System Service Ordinance (SDLWindV) which went into effect last year. Both regulations establish wide- ranging technical and operational requirements for wind turbines
In the coming weeks, REpower is already expecting further unit certificates for the MM series. For the new generation units of the 3.XM series, for which prototype testing will soon be carried out, unit certificates should be available in the fourth quarter of 2010 at the latest. Due to the prototyping regulation, the wind turbines of this series can be connected to the grid through the end of January 2011 without requiring a unit certificate and an expert’s opinion.
