Grid faults and load basis for wind turbines

The project developed a computer method for quantifying wind turbine structural loads caused by fault ride-through (FRT) requirements. Exemplified in the case of an active stall wind turbine this approach can be used by the industry as a wind turbine design tool. It is based on a combination of simulation tools with differing specialised expertise. Dynamic models and FRT control strategies for different wind turbine concepts were developed. Different storm management strategies were proposed and analysed. Statistical analysis for fatigue and extreme structural loads were carried out to analyse the impact of wind turbine structural loads. (Energy 10)
