PMG vs. DFIG – the big generator technology debate

The debate on which generator and converter option makes for the best modern wind turbine drive trains is still raging. When analyzed from either a total life cycle cost efficiency angle or a reliability angle, the PMG with a full-power converter (FPC) is by far the best technology, regardless of which key decision-making criteria is used.

The long-term advantage comes from the extra energy produced with the higher power curve efficiencies of PMG technology. This all leads to the lowest possible Levelized Cost of Energy (LCOE).
