Abstract
This article describes a methodology to quantify the influence of dynamic stall on transient
fault operations of active-stall turbines. The model of the dynamic stall effect is introduced
briefly. The behaviour of the dynamic stall model during a transient fault operation is
described mathematically, and from this its effect quantified. Two quantities are chosen to
describe the influence of the dynamic stall effect: one is active power and the other is time
delay. Subsequently a transient fault scenario is simulated with and without the dynamic
stall effect and the differences discussed. From this comparison, the conclusion is drawn that
the dynamic stall effect has some influence on the post-fault behaviour of the wind turbine,
and it is hence suggested that the dynamic stall effect is considered if an active-stall wind
turbine is to be modelled realistically.
