Wind turbine converters and generators need urgent reliability improvements for offshore turbines.
The study looked at over 6000 wind turbines in Denmark and Germany to see how reliable their parts are. They found that gearboxes in wind turbines are doing well, but generators and converters are not as reliable as in other industries. However, the reliability of generators and converters gets better over time. The researchers suggest that offshore wind turbines need better testing to prevent early failures, especially for converters and generators.
