Detection of Faults and Fault Tolerant Control Systems for Wind Turbines

 

Wind Energy Conversion (WEC) systems play a major role in the struggle to reduce greenhouse gases emissions and overall dependence on fossil fuels. The deployment of WEC systems started around 1980, and kept an impressive average growth rate of 30% per year since then. By 2050, wind power should cover 12% of the world’s energy needs, constituting the largest renewable energy source. This ambitious goal claims for more efficient on-shore/off-shore wind turbines, but that may require capital-intensive construction and maintenance. Therefore, the inoperative situations should be kept minimal, to ensure economic viability. This triggered the development of Fault Detection and Isolation (FDI) systems, which provide early warnings in presence of malfunctions. Implementing these systems yields several advantages, including the avoidance of premature breakdown and the reduction of maintenance costs. However, wind farm monitoring still relies on decisions of human operators or practical knowledge from experienced staff. Hence, this project pursues novel theoretically sustained FDI and Fault Tolerant Control (FTC) systems, driven towards fully autonomous operation. The foreseen methods build on recent advances in model falsification using set-valued observers and on LPV/BMI controllers for time-varying plants, guaranteeing maximum detection times for the faults, and ensuring closed-loop stability and performance.
