Up to one third of the Levelized Cost of Energy is related to operations and maintenance (O&M) of wind farms. Failure of wind turbine components causes considerable repair costs and cost due to lost production. Utilizing operational knowledge for reliability and O&M improvement is therefore key for further cost and risk reduction.
Today, there is still uncertainty during the O&M phase due to unquantified reliability of wind turbines and their components. This has a direct effect on modelling O&M processes as field-based and wind turbine technology-specific input is missing, particularly for recent turbine generations. Especially, the increase in wind turbine size and changing platform technologies make projections challenging.
At the same time, these projections are immensely important for future wind farm planning and successful bid preparation for respective auctions. This mini-symposium is aiming for reviewing lastest findings in the field of reliability modelling of current and future wind turbines. We are interested in discussing methods and field-data based results which are crucial input for various applications like O&M modelling, lifetime extension, yield forecasting and optimized control strategies.
