“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 -

Trend Advantages

Direct Drive

Eliminates gearbox failures

Eliminates gearbox energy

losses

Less than half the number of

components required in the

WTG

2. Higher Reliability and Reduced Drive Train Losses

3. Enhanced grid connectivity and Reduced Losses

9

Trend Advantages

Full Power Converter

Greater control and operational flexibility

Better fault ride through capabilities

Enables the ability to satisfy future grid

codes and requirements

Permanent Magnet Generator

Eliminates slip rings and associated

maintenance

Eliminates secondary winding losses

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
