Abstract
A braking system for a wind turbine is provided, and the wind turbine includes a rotor having at least one blade. A generator includes a plurality of stator windings having a plurality of phases. The braking system includes a plurality of resistors, and at least one switch connected between the stator windings and the resistors. The switch can be configured to connect the stator windings to each other via the resistors, for the effect of slowing down or stopping the rotor of the wind turbine.
