Sažetak
This paper deals with control algorithms that enable wind turbine operation during very high wind speeds (higher than cut-out wind speed) commonly referred to as soft cut-out strategies. The objective of this work was to find a methodology that will allow for an easy implementation of such algorithms to existing (operational) wind turbines. Therefore it was necessary to develop a design methodology that will assure that design driving loads are not increased with new controller actions. This is done by a dynamic approach in which power or rotor speed setpoint is varied on-line based on the current wind turbine state and wind speed worst case prediction. Firstly a linear optimisation problem is formed for finding the worst-case short-term scenario. The worst-case scenario is defined by the wind turbine loads -- the higher the loads, the scenario is considered to be worse. A fast and efficient way of solving worst-case prediction is found, which enables such algorithm to be implemented online.
