It is a constant speed generator with blade pitch controller, power transmission through a multiplier, and final adjustment of the turn rate by means of a hydraulic clutch located at the asynchronous generator admission which delivers the electric power. The equipment that can nowadays be seen in the workshops visited includes the hub, and there only needs to be added the 32 meters long three blades set, which is waiting to be assembled in their final destination, where they have been stored long ago. The aerogenerator design, components manufacturing and assembly have been calculated and verified according Class I + IEC standards. It is the first aerogenerator specifically developed for such wind speed and conditions. It has an integral control system which operates in a way that helps to obtain the best performance for the power delivered, under strict safety standards.
The foundation already made in the mounting site will receive the steel tower which has a total length of 70 meters and will weigh 120 tons, also manufactured in Comodoro Rivadavia. The nacelle, which contains the aforementioned generation set and weighs 70 tons, will be assembled in its upper part.
During the last days, the DEWI, European Institute for the certification of aerogenerators, has verified and tested in workshop the mechanical, electrical and electronic features, and controlled the tasks carried out by NRG personnel and providers. The approval achieved allows NRG Patagonia to perform the final transfer to the mounting site during the next weeks, and after that, to immediately proceed to the assembly and start-up.
The NRG 1500 will be set up in the EL TORDILLO wind farm, located 40 km. west of Comodoro Rivadavia, and it is part of the Vientos de la Patagonia Project I, implemented by ENARSA and Chubut Province.
