New-generation DFIG power converters for 6-8 MW wind turbine
DFIG topology wind turbines have been widely used in the wind energy market during the last years to cover the medium and lower power ranges, between 2 and 4 MW. Nowadays, this fact has changed and the OEMs are developing DFIG wind turbines that could go above power rates of 6 MW.
The wind sector is globally focusing its efforts on reducing the Levelized Cost of Energy (LCoE) of the technology in order to prove itself as a profitable option in the energy mix regarding electrical generation. In response to this market outlook, OEMs are working hard to develop wind turbines with a power range exceeding 6 MW, which potentially enables the reduction of the LCoE of the wind farm.
In addition, the increasing penetration of wind power capacity into the grid creates new challenges for the Transmission System Operators (TSO) in order to keep the stability of the transmission system. As a consequence, grid codes around the world are strengthening their requirements to meet more demanding conditions such as FRT (Fault Ride-Through) behavior or harmonic distortion compliance.
