Abstract

The invention relates to a braking device for a wind power plant. The wind power plant comprises a rotor (12) that converts wind energy into rotational motion. The rotor drives an electric generator (14) whose electrical power can be fed into an electrical power grid. The braking device contains a hydraulically actuated brake (21) for the rotor, a hydraulic valve (40), which controls the supply of pressure medium to the brake, and contains a regulating device (44) that produces a control signal for the hydraulic valve. In order to improve the behavior of the wind power plant during braking, a regulating device (44) is provided that has a control circuit for controlling the pressure of the pressure medium supplied to the brake. The output signal of a pressure sensor (23), which is subjected to the action of the pressure, is fed to the pressure control circuit. A pressure regulator forms the control signal for the hydraulic valve based on the difference of the pressure actual value from a pressure set value. The invention also relates to a method for operating said braking device.
