Abstract

The invention relates to the field of brake of wind generating sets, in particular to a wind generating set, and a yawing brake device, a brake system and a brake method for the wind generating set. The yawing brake device comprises a brake disc, a friction plate and a pushing component. After the wind generator set is mounted on a wind generating set base, the surface of the brake disc is parallel to the wind generating set base. The friction end of the brake disc is in contact with the friction surface of the friction plate. A pushing end of the pushing component is propped against the pushing surface of the friction plate. The friction plate is perpendicular to the wind generating set base. Powder generated after the friction plate is in friction with the brake disc can fall automatically under the action of gravity, powder accumulated on the friction plate does not need to be removed manually, the problems of friction coefficient variation, the yawing vibration and the yawing abnormal sound between the friction plate and the brake disc can be avoided, and normal brake of the friction plate and the brake disc is not interfered.

Description

technical field [0001] The invention relates to the field of braking of wind power generating sets, in particular to a wind generating set and its yaw braking device, braking system and braking method. Background technique [0002] At present, the yaw system is one of the essential components of the horizontal axis wind turbine. The yaw system serves two main purposes. One is to cooperate with the control system of the wind turbine so that the wind rotor of the wind turbine is always in the windward state, making full use of wind energy and improving the power generation efficiency of the wind turbine; the other is to provide the necessary locking torque to ensure the wind power safe operation of generator sets. Such as figure 1 , 2 As shown, the axial pressure of the brake is applied to contact the brake disc 101, and the friction powder is not easy to be discharged automatically. The friction powder is easy to adhere to the surface of the friction plate under the actio...
