ReGen Powertech leading wind turbine manufacturer of India, is introducing India's largest wind turbine WD 2.8 with a rated power output of 2.8 MW and rotor diameter of 109 meters.

This is the largest capacity turbine with the biggest rotor diameter to be developed in India. Entirely designed and developed by ReGen's own R&D subsidiary in Germany, Wind Direct GmbH, this turbine has many unique design and constructional features.

Primarily developed for the medium and high wind regions, this turbine is mainly intended for export to the emerging markets outside of the Indian subcontinent. It is expected that the introduction of this new turbine, a proto type of which is under testing in ReGen's own test site in Coimbatore district of Tamilnadu, will mark ReGen's foray into the global arena.

Wind Direct GmbH Germany, established in the year 2008, is headed by Dr.-Ing. Stephan Joeckel, who has more than twenty years of experience in the development of direct drive wind turbines. He has a team of twenty five highly qualified and experienced engineers based in Mannheim, Germany and in Chennai.

The team is fully equipped with state of the art software tools required for the design and development of wind turbine and has the competence to carryout load calculations, finite element analysis and detailed engineering and design of electrical systems including frequency converters.

The permanent magnet synchronous generator of this turbine has very unique design and construction features and offers distinct advantage over the generators used in geared turbines as well as gearless turbines. The generator of WD 2.8 offers IP 54 protection compared to IP 23 protection normally available for generators of other gearless wind turbines.

The generator is of segmental design and has two fully independent power systems, each of 1.4 MW capacities.  This allows operation of the turbine at half the rated power in case of any maintenance to some of the segments of the generator.
