Generators are where wind energy — captured by the blades, coiled through the drivetrain — becomes power. Here, the double-fed induction generators (DFIGs) that have been fundamental to the modern turbine’s development are pitted against permanent-magnet generators (PMGs), whose high-efficiency, light-maintenance regimes have turned many in favour of the technology.
The subject was debated by a panel of experts at Recharge’s Technology roundtable discussion at WindEnergy Hamburg in September.
“When
