1. Brake failure: when the wind turbine runs too fast or too fast, the unit needs to brake to slow down, but if the brake fails, the unit is prone to safety accidents. The reason may be the brake system gear damage, brake wheel drum wear and so on. To solve the problem, you need to replace the damaged parts in time, take some preventive maintenance measures, and strengthen the detection and maintenance of the brake system.

2. Generator failure: Wind turbine generator failure can be due to overheating, lack of lubrication, blade damage, and so on. To solve this problem, we can slow down the running speed of the unit, replace the damaged blades, and strengthen the maintenance of the generator.

3. Cable failure: The cable of wind turbine is easy to be damaged by animals, oxidation, extrusion and other reasons, resulting in interference or interruption of signal or power transmission. To fix the problem, replace the damaged cable or repair the damaged part. In addition, it is necessary to strengthen the maintenance of the cable.

4 bearing failure: bearing failure will lead to unstable operation of the unit, noise increase and other adverse effects. The reason may be bearing wear, excessive fatigue and so on. To solve the problem, bearings can be regularly tested and maintained, and damaged bearings can be replaced in time.

5. Blade damage: The blades of wind turbine may be damaged due to wind or other reasons, resulting in the unit can not work normally. To solve the problem, the damaged blade can be replaced in time, and the maintenance and detection frequency of the blade can be strengthened.

6. Control system failure: Failure of the wind turbine control system will cause the unit to fail to operate in the expected manner. The reason may be circuit break, power failure and so on. To solve this problem, it is necessary to check and maintain the control system regularly.
