The Switch, manufacturer of permanent magnet generators and full-power converters, recently released a technology paper addressing the ongoing industry debate on drivetrain technology selection. With this paper, the Finnish manufacturer tackles the performance misconceptions still surrounding the main two drivetrain technologies that currently dominate the wind energy industry and explains why the permanent magnet generator (PMG) with a full-power converter (FPC) will emerge as the clear drivetrain technology of choice for modern wind turbines.
“In the wind power industry, the debate on which generator and converter option makes for the best modern wind turbine drivetrain is still raging,” says Jukka-Pekka Mäkinen, The Switch CEO. “Numerous technology experts and industry commentators promote the use of the double-fed induction generator technology, while expressing doubts about the advantages of the PMG approach. In this paper, we aim to set the record straight and explain why PMG with a FPC is by far the best technology, regardless of which key decision-making criteria you use.”
“PMG-FPC drivetrains work out to be a cheaper, more cost-effective option over the total life cycle of the turbine,” he continues. “Moreover, PMG-FPC simplicity leads to superior reliability and higher availability. Many turbine manufacturers still rely on outdated generator technology choices. For those businesses choosing to adopt PMG-FPC drivetrain technology, accepting a steep adaptation curve in the short term will enable them to reap the benefits of superior AEP in the medium and long term.”
