Abstract:
Based on comprehensive field data covering more than 22,000 operating years of onshore and offshore wind turbines on four different continents, we present failure rates for the main components of the converter system, investigate their failure behavior with respect to trends and identify both design-related and site-specific factors having a significant effect on converter reliability.
