Problems solved by technology

[0002] The yaw system is a unique control system for wind turbines. The yaw control system is mainly composed of three parts: yaw measurement, yaw drive transmission part, and cable protection device. It mainly realizes two functions. One is to make the nacelle track and change stably The second is that due to the yaw effect, the cables inside the nacelle are automatically unwound due to the entanglement of the cables. Due to the harsh working environment of the wind turbine, this requires a long maintenance cycle for each component, which is convenient for reducing maintenance costs and extending working hours, but the gearbox of the wind turbine has the problem that it is often damaged prematurely by the shock load during braking

Embodiment Construction

[0007] The yaw navigation system includes a wind vane that senses wind direction, a yaw motor, a yaw planetary gear reducer, a large gear of a gyratory body, etc. The wind vane is used as a sensing element to transmit electrical signals of wind direction changes to the processor of the control loop of the yaw motor After comparison, the processor sends a clockwise or counterclockwise yaw command to the yaw motor. In order to reduce the gyro torque during yaw, the motor speed will be decelerated by the coaxially connected reducer, and the yaw torque will be applied to the rotation The large gear on the body drives the wind wheel to yaw against the wind. When the wind is completed, the wind vane loses the electrical signal, the motor stops working, the yaw process is over, the yaw is braked, and the rotation direction of the main engine room is in accordance with the commanded direction. When the yaw motor rotates, the hydraulic brake system is in the released state, and when the...
