Abstract
A wind turbine includes wind turbine blades, a wind turbine rotor coupled to the wind turbine blades, a wind turbine generator coupled to the wind turbine rotor, a wind turbine converter coupled to the wind turbine generator, a controllable brake comprising one or more sources of controllable rotor torque adjustment for providing a first level of torque adjustment, a discrete brake for more coarsely providing a second level of torque adjustment, and a controller programmed for responding to a deceleration event by determining a required torque adjustment for braking, determining a sequence of applying the controllable brake and the discrete brake for driving a combination of the first and second levels of torque adjustment towards the required torque adjustment, and providing control signals for decelerating the wind turbine.
