  • 7. 2. Higher Reliability and Reduced Drive Train Losses Trend Advantages Eliminates gearbox failures Direct Drive Eliminates gearbox energy losses Less than half the number of components required in the WTG “It was the PMG’s greater efficiency in part load operation that led GH to conclude it was the superior generator for economic wind energy conversion” -Garrad Hassan 8
  • 8. 3. Enhanced grid connectivity and Reduced Losses Trend Advantages Greater control and operational flexibility Full Power Converter Better fault ride through capabilities Enables the ability to satisfy future grid codes and requirements Eliminates slip rings and associated maintenance Eliminates secondary winding losses Permanent Magnet Generator Superior part-load efficiency as there are no requirements for generator excitation Reduction in size and mass of typical direct drive generator High power to weight ratio 9
