The Senvion 3.2M122 turbine will use the new NES system, which includes a "fully rated" converter, as opposed to a partial converter used in previous models.

There is also an upgraded asynchronous doubly fed induction generator, which the company said would help lower the cost of energy.

Senvion said the new system was designed to help integration with grid networks by providing a more stable supply of electricity.

The 3.2MW, 122-metre diameter rotor turbine can be used for low-wind sites, making it a larger capacity option than Senvion's 3MW turbine with the same rotor size.

Senvion said the NES turbine would comply with German grid requirements for high voltage connections due to come in force from January 2017. 

The company's 3.XM platform also comprises two 3.2M114 turbines, and 3.4M104 and 3.4M114 units.

The German firm, currently owned by Indian manufacturer Suzlon, is in the process of being acquired by Canadian private equity firm Centerbridge Partners.
