Abstract
Loads reduction method in a wind turbine for power-grid disconnection during a wind gust, which uses a control system made up of three loops used to correct the speed at which the wind turbine blades are moved to the feathered position throughout a controlled emergency stop, with a non-linear law that takes into account blade position, tower vibrations and generator rotation speed limits.
