The Nordex Group has obtained key Spanish grid approvals for its N149/4.0-4.5 turbines.
The German manufacturer said it has acquired the Equipment Certificate (UGE) as well as the Component Certificate (CAMGE) for its own Wind Farm Controller (CWE).
Both certificates confirm the required standard-compliant grid connection behaviour according to the Norma Técnica de Supervisión 2.1 (NTS) by the FGH certification body, said Nordex.
The certificates have been required for the connection of wind turbines to the grid in Spain since mid-2020 and have to be provided within two years, added the company.
These tests mean that certain technical requirements have to be met, such as the behaviour in the event of voltage dips in the grid, the recovery of active power after a grid fault and the power frequency control of the turbines and the entire wind farm at the grid connection point.
Measurement of the N149/4.0-4.5 was conducted in Germany in the Wennerstorf wind farm to the south of Hamburg.
The Nordex Group is currently supplying ten N149 turbines for the Celada Fusión wind farm in the region of Valles del Cerrato, in the province of Palencia in the north of Spain.
This is the first wind farm in Spain with N149 turbines.
